Build a complete electrical schedule. Protection, control, connectivity and solar.
Source low-voltage circuit protection, transfer switches, contactors, starters, distribution boxes, smart gateways and solar electrical products. Match individual ratings, protection functions, mounting, communication and documents to the installation.
Manufacturing, product documents and order conditions depend on the model and supply route selected for your project.
Start with a product reference, intended use and estimated quantity. We bring product selection, sample questions and quotation details into one conversation.
Email your reference image ↗Choose a focused product or discuss a coordinated assortment. Each direction can be developed into a more specific model and packaging brief.
Build modular protection assortments around rated current, poles, trip characteristic, supply and verified breaking capacity. References cover different ratings and form factors, including compact neutral-pole arrangements. Match busbars, conductor capacity and mounting before treating devices as interchangeable. The short-circuit rating and standard must be stated with the selected version.
Enquire about this range ↗RCCB directions provide residual-current switching without integral overcurrent protection; RCBO directions combine residual-current and overcurrent functions. Specify the sensed waveform type, rated residual current, poles, neutral arrangement and time response. Select upstream protection and coordination for the actual circuit. Different residual-current types are separate options, not simultaneous functions in every unit.
Enquire about this range ↗Thermal-magnetic, electronic-trip and earth-leakage MCCB directions support different protection requirements. State frame size, rated current, operating voltage, poles, trip settings and required Icu/Ics. Ask for the corresponding time-current curves, terminals, accessories and outline. A maximum series rating does not establish every combination of frame and voltage.
Enquire about this range ↗ACB directions address incoming and outgoing distribution feeders and larger equipment circuits. Specify the current rating, trip unit, fixed or draw-out arrangement, control voltage and accessory list. Request the installation drawing, interlocking, protection curves and operating conditions for the exact assembly. The switchboard design must accommodate clearance and thermal requirements.
Enquire about this range ↗PC-class and CB-class transfer-switch directions cover different changeover requirements. Provide the two supply systems, circuit rating, poles, neutral strategy, transfer sequence and controller functions. Agree generator signals, manual operation, electrical/mechanical interlocks and any fire interface. Transfer switching should be assessed with the associated protection and load.
Enquire about this range ↗Load-break switches, switch disconnectors, fuse-combination switches, fuse disconnectors and low-voltage fuses form a separate coordination group. Specify duty, utilization category, fault level, fuse size and access requirements. Request compatible handles, shafts and terminal covers. An isolation function does not automatically provide overload or residual-current protection.
Enquire about this range ↗Type 2 AC surge-protection directions and separate DC devices support different circuits. State the earthing arrangement, operating voltage, protection level, discharge ratings and backup protection. Compare replacement cartridges and status or remote indications where required. Match the actual device to the protection design; a Type 2 description does not establish direct-lightning protection.
Enquire about this range ↗Plastic, metal and metal-base distribution directions support modular equipment installation. Choose surface or flush construction, module count, rows, door style, terminals and cable entry. Review the assembled configuration and destination requirements. An enclosure IP designation is specific to that construction and installation, not a blanket rating for every board.
Enquire about this range ↗The range includes conventional and miniature contactors, modular contactors and capacitor-switching directions. State motor or other load duty, operating voltage, current, coil supply, auxiliary contacts and switching frequency. Capacitor switching needs its own inrush and compensation brief. Select power ratings at the actual voltage and utilization category.
Enquire about this range ↗Thermal overload relays and motor-protection circuit breakers support coordinated motor circuits. Provide motor nameplate data, starting method, full-load current and operating conditions. Select the appropriate adjustment band, trip behaviour, contactor and short-circuit protection rather than assuming a series-wide adjustment range applies to a single device.
Enquire about this range ↗Direct-on-line, enclosed and star-delta starter directions support different motor-starting arrangements. Soft-starter cabinets are also a project enquiry direction. Submit the motor and supply details, starting duty, control sequence, enclosure and protection requirements. Agree the assembly drawing and bill of materials before comparing complete cabinet quotations.
Enquire about this range ↗Smart breaker, residual-current breaker and switching directions connect local circuit operation with monitoring and remote control. Specify the protection function separately from communication features. Establish which electrical quantities are available, control permissions, alarm behaviour and operation after a network interruption. Connected operation requires the correct gateway and compatible system.
Enquire about this range ↗Gateway directions include cellular, Wi-Fi, wired-network and other communication versions. Confirm the regional network, device protocol, compatible circuit count and software arrangement. Define account ownership, data access, remote switching permissions and support. A gateway variant does not automatically include every communication method or every software feature.
Enquire about this range ↗Photovoltaic directions include combiner boxes, DC breakers, isolators, surge devices and fuses. Provide array voltage, string currents, input/output count and prospective fault conditions. Request the actual connection arrangement, polarity instructions, monitoring options and enclosure information. AC switchgear ratings must not be substituted for DC ratings.
Enquire about this range ↗PV modules, solar inverter directions, microinverters and AC vehicle-charging equipment can be included in a renewable-energy enquiry. Select them by the intended system architecture and local connection requirements. Confirm voltage windows, operating power, communication, protection and documentation. A product family does not establish a complete compatible solar or charging system.
Enquire about this range ↗Single- and three-phase stabilizer directions include different orientations and display formats. Adjustable voltage regulators, control transformers, switching power supplies and sine-wave inverter directions broaden the power-conversion range. Define input, output, frequency, load, waveform and duty separately for each item. A stabilizer and an adjustable regulator perform different tasks.
Enquire about this range ↗Analogue and digital panel meters, electronic energy meters and current transformers support monitoring and panel design. Specify the quantity measured, input arrangement, CT ratio, panel cut-out and accuracy requirement. Confirm communication, wiring and calibration evidence where needed. Do not assume a monitoring display is approved for revenue billing.
Enquire about this range ↗Pushbuttons, indicators, control stations, toggle, pedal, micro, limit, rotary and float-switch directions address different control functions. Time relays, power relays and relay sockets complete control-panel enquiries. Provide contact function, actuator, mounting, electrical duty, environmental exposure and label requirements for the selected item.
Enquire about this range ↗Industrial plugs and sockets, modular sockets, breaker auxiliaries, busbar-related accessories and distribution-box fittings can be specified with the protection schedule. Confirm pin arrangement, current, voltage, pole configuration, mounting and compatibility. Auxiliary contacts, alarms, undervoltage releases and shunt releases require a matching host device and control supply.
Enquire about this range ↗Low-voltage distribution cabinets, soft-starter cabinets, street-lighting control boxes and outdoor electrical control boxes are project directions. Submit a single-line diagram, enclosure environment, fault level, control philosophy and installation constraints. Request the assembly-specific documentation, acceptance tests, labelling and service scope before order approval.
Enquire about this range ↗Cable trunking, H-form terminal blocks, medium-voltage vacuum switching and dropout-fuse requirements can be submitted as separate project briefs. Confirm the current article and supply scope, system ratings, drawings and required evidence before including these items in an order.
Enquire about this range ↗Use these options to describe what you are buying. The public references identify your enquiry; the final model and specification are confirmed before an order.
An AC modular protection reference with selectable poles, current and trip curve. Select the actual combination and confirm coordination with the circuit fault level and busbar.
A combined residual-current and overcurrent reference. Keep the two breaking-capacity figures tied to their cited standards rather than presenting them as one interchangeable rating.
A residual-current switching direction requiring coordinated overcurrent protection. Select the exact waveform response and residual-current rating for the installation.
An automatic transfer direction for two AC supplies. The upper current value is a series limit; select the frame, poles and controller for the actual load and changeover design.
A moulded-case reference covering different frame sizes. The short-circuit rating must be confirmed for the selected frame, voltage and variant from a clear schedule.
A Type 2 direction for a coordinated protection design. Request the actual voltage, discharge ratings, protection level and backup-device requirements.
A plastic enclosure range with different capacities and door materials. Confirm the mounting version and completed assembly before selecting the enclosure.
An overload-relay direction offering multiple adjustment bands across the catalogue range. Choose a band around the actual motor current and confirm the mating contactor.
A motor protection direction with overload and short-circuit functions. Select a specific adjustment band, enclosure and accessories for the circuit.
A gateway direction for compatible smart switching devices. Network versions are alternatives; confirm regional support and software arrangements.
A smart AC protection direction supporting local operation and gateway-based remote operation. Match the system, measured quantities and protective functions to the actual model.
A PV-array connection direction between modules and the inverter. Define string inputs, current, voltage, isolation, surge protection and monitoring for the required configuration.
A DC-specific protection reference. Voltage ratings are linked to pole configuration; request the exact series connection, polarity and circuit instructions.
Auxiliary contacts, alarms and releases should be selected for the exact host series and control function. Confirm wiring, coil voltage and mechanical compatibility.
All figures are catalogue references for the individual product direction. Current ranges span different variants; breaking ratings, residual-current types, voltage/pole mapping and standard references must remain attached to the selected device. Request the final schedule, drawings and supporting product documents before approval.
Focus the sourcing conversation on the features, materials and production details that make a difference to your product range.
Combine modular protection, industrial switching, motor control, smart monitoring and solar DC items in one schedule. Review interfaces, enclosure space and accessory compatibility while comparing the bill of materials, rather than selecting unrelated components only by price.
Smart breaker and gateway directions allow a brief that covers protection, local operation, remote permissions and circuit data. Define the actual software, communication version and behaviour under loss of connectivity so the selected system meets the project requirements.
Discuss catalogue components, selected customization and project cabinet configurations separately. Prepare the operating conditions and drawings early, then align samples, labelling, technical files and pack data with the actual configuration.
Bring artwork, reference samples and a target cost. The available process, minimum quantity, sample charges and development scope are reviewed for the chosen option.
Send model direction, current, poles, voltage, trip type, quantities and destination. Add artwork, colour or pack requirements and any design changes. OEM/ODM enquiries can be evaluated against the selected line; feasibility, tooling, testing and MOQ require a written quotation.
Request the specific current and pole version with its accessories. Agree sample charges, preparation time and inspection criteria. Record the approved datasheet, product markings, curves and drawings; a sample of another variant should not approve the whole series.
For boards or cabinets, provide a single-line diagram, device schedule, control sequence and enclosure requirements. For components, define unit boxes, carton quantities, labels, instructions and traceability. Confirm packing dimensions and weights for the actual order before estimating freight.
Agree which product characteristics need testing and how the approved sample relates to the bulk order.
Request the product-specific verification plan for operating characteristics, temperature rise, electrical/mechanical endurance, residual-current operation, insulation and relevant environmental or EMC requirements. Agree applicable standards, sampling, acceptance criteria and records for the selected device.
Check actual current/poles, trip unit, coil/control voltage, accessory fit, busbar compatibility and terminal requirements. Review smart communication and gateway pairing, and DC polarity/series wiring for PV components. Confirm that markings and instructions match the supplied version.
Agree incoming/process/final inspection records and batch identification. Keep the order reference, product trace number and evidence needed for a service claim. Warranty duration, exclusions, replacement arrangements and spare-parts scope belong in the quotation for the specific products.
Test capability is a starting point for the inspection plan. Request the method, applicable model and results needed for your order.
Prepare model-specific electrical documentation and an installation schedule. Published laboratory history or a certificate title does not establish current approval for an entire product range; confirm scope, status and the actual supplied version.
State the sales market, intended users and required files in your first enquiry. Current validity and scope are checked for the selected supplier and product; a category description does not certify every item.
Share your document requirements ↗Your sales channel changes the assortment, packaging and quality priorities. Tell us the intended use as well as the product name.
Prepare a coordinated component schedule for residential, commercial or industrial distribution. Match protection, switching, enclosure space, terminals and control supplies to the installation drawing and destination.
Combine feeder protection, motor-control and transfer-switching directions with the project duty and fault levels. Add cabinet requirements, control sequences, interlocks and an assembly acceptance plan.
Define circuit monitoring, remote-control permissions and software integration alongside protection. For solar or charging projects, provide the actual system architecture, DC/AC ratings and required market documents.
Samples, commercial terms and responsibilities are agreed for the project. Use the same product and packing specification when comparing quotations.
Product, reference image, quantity, sales market and timing.
Review configuration, materials, sample scope and relevant documents.
Agree artwork, packaging, sample, testing and inspection criteria.
Set price, payment, production, delivery and defect remedies in writing.
Practical answers about this sourcing direction, customization and the reference options. Your agreed specification and written quotation determine the actual order.
Yes. Include transfer switches, isolation, fuses, contactors, starters, enclosures, metering, controls, power conversion, smart devices and solar electrical directions. Separate the schedule by item, rating and quantity so compatibility and availability can be checked.
An RCCB provides residual-current switching without integral overcurrent protection. An RCBO combines residual-current and overcurrent protection. Specify the required waveform type, current, residual sensitivity, poles and time response for the circuit.
Provide current, poles, voltage, frequency, trip characteristic, breaking capacity, reference standard and mounting/busbar requirements. Add destination, quantities and accessories. Equal current ratings do not establish equal fault performance or compatibility.
The reference lists Icn under IEC 61009-1 and Icu under IEC 60947-2. They should remain identified with their standard and test basis. Ask for the exact rating and supporting evidence required by your design.
Use a device selected for the actual DC voltage, current, pole connection and polarity conditions. Request the applicable DC documentation and wiring instructions. An AC catalogue rating is not a substitute for a DC rating.
No. The 3,200 A figure is the upper catalogue limit for a PC-class direction. Confirm the selected current/frame, poles, control supply and transfer functions, together with upstream protection and installation details.
The gateway has different communication versions. Select the actual 4G, Wi-Fi, wired LAN or other supported version and verify regional network support, compatible devices, software, accounts and permissions.
That is family coverage across different variants. Select a particular relay adjustment band around the motor current and confirm trip characteristics, reset and contactor compatibility. The same principle applies to the motor-protection breaker range.
Provide the single-line diagram, device schedule, fault level, enclosure environment, control sequence and installation constraints. Cabinet configuration, acceptance tests, documentation and support need to be agreed for the actual assembly.
Send the selected product, artwork, packing and any technical changes for review. Sample availability, charges, timing, customization feasibility and minimum quantities are product-specific quotation items. Approval should refer to the actual configuration.
Each claim must be checked against the model, rating, report scope and current status. Request the underlying documents needed for your market. A general certificate catalogue or laboratory history does not approve every device or complete assembly.
These depend on model, rating, quantity, raw materials, customization and packing. Request a written schedule and commercial terms for the order. Agree warranty conditions, traceability and any spare-parts support rather than applying one generic policy to all products.
