Specify protection around the circuit. Coordinate the enclosure and connections.
Source circuit breakers, residual-current and arc-fault protection, surge devices, DC protection, distribution boxes, cabinets and connection accessories. Compare model-specific ratings, installation, control functions and private-label requirements for your market.
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.
MCB directions support modular overcurrent protection across different current ratings, poles and breaking-capacity levels. Specify the supply, load, trip curve, prospective fault level and reference standard. Match terminals, busbar arrangement and module space before replacing or combining devices. Family maxima and different form factors should remain separate in the order schedule.
Enquire about this range ↗RCCB directions use different waveform responses, sensitivities and time characteristics. Specify the current, pole arrangement, residual-current rating and coordination with upstream overcurrent protection. Electromagnetic and different residual-current types should be selected for the actual installation. A conditional short-circuit figure is not an unconditional standalone interruption rating.
Enquire about this range ↗RCBO directions combine residual-current and overcurrent functions in one device. Options span different pole layouts, currents, sensitivities and trip curves. Provide the neutral arrangement, circuit duty and required waveform response. Confirm the actual operating technology, installation width and supporting documents for the selected version.
Enquire about this range ↗Arc-fault directions combine detection with other circuit-protection functions on selected devices. Define the required residual-current type, overcurrent characteristic, poles and supply. Request the exact arc-fault and RCBO technical evidence. Arc-fault detection supports a protection design but should not be promoted as preventing every fire or detecting every possible fault.
Enquire about this range ↗DIN-rail surge devices provide a separate transient-overvoltage protection direction. State the network, operating voltage, earthing system, discharge ratings, protection level and backup device. Confirm the actual SPD type, replaceable parts and indication. Keep AC and photovoltaic DC applications distinct and request the applicable documentation for the chosen construction.
Enquire about this range ↗DC MCB and DC surge-protection directions support photovoltaic and other DC-distribution enquiries. Define maximum circuit voltage, current, pole connection, polarity and fault conditions. Request DC-specific curves, wiring and coordination. A family reference to a high DC voltage cannot be applied to every pole count or every variant.
Enquire about this range ↗Isolator and main-switch directions support local switching and isolation in low-voltage distribution. Specify poles, current, utilization duty, operating voltage and required indication or locking. Confirm the selected terminals and mounting arrangement. Isolation should be coordinated with separate protective devices where those functions are required.
Enquire about this range ↗MCCB directions address feeder circuits and industrial or commercial distribution. A connected reference combines protection with measurement and communication functions. Define rated current, fault performance, trip behaviour, measurement requirements and interface. Network support and software integration must be agreed for the actual product; communication features do not establish billing-meter approval.
Enquire about this range ↗Plastic boxes include different module counts, rail layouts and mounting arrangements. Select the actual enclosure, door, cable entry, seals and terminal accessories for the environment. Enclosure protection depends on the supplied construction and installation. Approve dimensions and pack contents from the selected drawing rather than a similar-size catalogue image.
Enquire about this range ↗Metal directions include indoor and outdoor distribution formats, galvanized-steel and stainless-steel constructions, and different mounting arrangements. State module count, rows, cable entry, door and locking requirements. Review whether the quotation is for an empty enclosure or an equipped assembly and confirm the actual ingress-protection requirement.
Enquire about this range ↗Roll-formed and welded modular steel cabinet directions provide removable or screw-fixed panels, doors and mounting plates for equipment integration. Define the equipment layout, mounting loads, cable routes, finish and access requirements. Ask for the actual dimensioned drawing, plate thicknesses, hardware and protection evidence for the configuration.
Enquire about this range ↗PV grid-connection and energy-storage enclosure directions address the housing and integration brief. Define the AC/DC boundaries, equipment layout, thermal management, cable entries and environment. Cooling or insulation options require engineering review. A cabinet offering does not establish supply of a complete battery system, inverter package or grid-approved energy-storage installation.
Enquire about this range ↗Wall-mounted and floor-standing steel power-cabinet directions can be discussed for commercial or industrial projects. Top/bottom cable access, removable service panels and handling fittings need to match the installation. Provide the single-line diagram and component schedule, then agree whether scope includes an enclosure, fitted board or complete tested assembly.
Enquire about this range ↗Copper busbar directions include different pole arrangements, pitches, terminal shapes and current references. Distribution blocks provide another connection direction. Submit the device layout, conductor details, feed position and enclosure conditions. Confirm mating dimensions, insulation, end protection and temperature-rise evidence for the actual connection system.
Enquire about this range ↗Accessories include auxiliary contacts, alarm combinations and shunt-release directions. State the host breaker series, contact function, control supply and wiring requirements. Mechanical fit and electrical compatibility should be confirmed for the exact host/accessory combination. A release or indication module does not add every protective function to the base device.
Enquire about this range ↗Connected protection and the broader smart-electrical/industrial-control directions can be included in a project brief. Specify the intended monitoring, switching, communications and software arrangement. Contactor or additional specialist-control requirements should be submitted for availability review with their exact ratings; component and enclosure supply scopes should be kept clear.
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.
A single-pole AC direction with a C-curve selection table. Request the exact rated-current version and verify the markings and current technical sheet before sample approval.
A three-pole reference for a higher-current schedule. The listed current choices are separate versions, and ultimate/service breaking figures retain their individual labels.
A residual-current family reference covering multiple current and pole versions. Select the actual waveform/time response and coordinate its conditional short-circuit rating with the required upstream device.
A compact combined residual-current/overcurrent reference for a single-phase schedule. Confirm the current technical file, neutral connection and breaking-capacity test basis for the selected version.
An integrated arc-fault direction with a B-curve technical table. Select the actual rated-current version and residual sensitivity, and request both arc-fault and combined-protection documentation.
A DC-specific reference for PV and battery-distribution matching. Approve the actual pole wiring and product instructions for the system.
A modular AC surge-protection direction for a coordinated installation. Specify the exact model and ratings before selecting backup protection or preparing a listing.
A feeder-protection reference with monitoring and communication directions. Define the actual interface configuration and protection settings before comparing the integration scope.
A plastic enclosure reference with a stated ingress-protection designation. Request a version-specific drawing; do not use a neighbouring size’s dimensions for the selected box.
A metal-board direction for choosing the module layout, material and installation. Range limits cover different products and do not define one interchangeable enclosure.
A modular enclosure direction with roll-formed/welded construction and screw-fixed panels. Confirm the specific series and drawing before comparing protection, loads or fit.
A cabinet direction for solar grid connection and storage-related integration. Specify the actual enclosure and thermal-management design; electrical equipment and battery supply are separate scope items.
A steel cabinet direction with service access and cable-entry options. Provide the layout and installation conditions so the enclosure or fitted assembly can be quoted accurately.
A specific connection direction for a compatible breaker layout. Confirm pole sequence, insulation, end caps, feed arrangement and mating terminals before approval.
Values refer to the individual catalogue direction and selected variants. Conditional RCCB short-circuit current, breaker Icu/Ics, DC voltage/pole arrangements and enclosure IP designations must retain their stated basis. Confirm the current drawings, markings, technical file and quotation before using a number in a project or listing.
Focus the sourcing conversation on the features, materials and production details that make a difference to your product range.
Compare breakers, residual-current and arc-fault devices, surge protection, boxes, cabinets and connections in one technical schedule. Confirm the component fit and actual supplied scope while developing the bill of materials, pack data and market-document list.
Separate overcurrent, residual-current, arc-fault, surge and isolation requirements before selecting ratings. This supports a clearer comparison of basic, combined and connected product directions, including AC and DC circuits with different technical requirements.
OEM/ODM directions support discussion of product appearance, markings, handle colours, technical requirements and packaging. Feasibility and any additional testing must be reviewed for the selected product so the approved sample, artwork and technical file describe the same version.
Bring artwork, reference samples and a target cost. The available process, minimum quantity, sample charges and development scope are reviewed for the chosen option.
Provide destination, voltage, frequency, poles, rated current, trip curve, residual-current type/sensitivity and desired functions. Add installation constraints, drawings and quantities. Technical changes require an agreed development and validation plan rather than assuming every series can be modified in the same way.
Sample enquiries can be evaluated with the selected ratings and construction. For development projects, agree drawings, modelling/prototype steps and any market testing before bulk approval. Confirm sample availability, charges, preparation time and acceptance criteria in the quotation.
Discuss logo placement, pad/laser marking where suitable, handle/casing colours, retail boxes, cartons and manual language. Prepare artwork without unsupported conformity or performance claims. Obtain version-specific unit/carton dimensions, weights, accessories and identification for freight and order planning.
Agree which product characteristics need testing and how the approved sample relates to the bulk order.
Request the applicable verification for trip operation, temperature rise, short-circuit performance, residual-current operation, insulation and endurance. Arc-fault devices, surge protection and enclosures require their own test scopes. Agree sampling, acceptance records and the exact technical standard with the selected configuration.
Check poles, terminals, rail space, busbar pitch, contact/release compatibility and the actual supply. For enclosures, verify drawings, doors, plates, seals, cable entry and installation. For connected protection, agree communication, account/software scope and behaviour without connectivity.
Keep the approved sample, rating sheet, drawings, artwork, inspection records and packing specification together. Agree batch identification, service evidence and any spare parts. Warranty duration, exclusions and replacement arrangements need order-specific confirmation for components and assemblies.
Test capability is a starting point for the inspection plan. Request the method, applicable model and results needed for your order.
Request documents for the actual model, rating, construction and destination. Range-level marketing, a certificate label or a group-level manufacturing statement does not establish current approval for every product or assembly.
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.
Develop modular protection and consumer-unit assortments around the supply, circuit schedule and local requirements. Define residual-current and arc-fault functions, box capacity, connection system and instructions for each version.
Coordinate feeder protection, connected functions, cabinet/enclosure construction and accessories with the project drawing. Review fault levels, terminals, clearances, heat and access before comparing an equipped assembly.
Specify DC protection and surge coordination alongside the AC-side distribution and enclosure brief. For a branded retail programme, align individual ratings, approved samples, artwork and market-specific documentation.
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.
Include MCBs, RCCBs, RCBOs, arc-fault protection, surge devices, DC breakers, isolation, MCCBs, distribution boxes, cabinets, busbars, blocks and compatible auxiliaries. List the function, rating and quantity separately so the actual configuration and supplied scope can be reviewed.
Specify current, poles, supply, frequency, trip curve, fault level, reference standard and installation. Add terminal/busbar requirements and any auxiliaries. Similar current ratings do not establish equal breaking capacity or fit.
An RCCB is a residual-current device without integral overcurrent protection. Coordinate it with the necessary upstream device and fault conditions. An RCBO combines those functions, but still requires selection for the actual circuit.
Keep the figure tied to its specified protective-device conditions and supporting documentation. Request the coordination information for the selected version rather than treating a conditional value as an unrestricted standalone breaker rating.
Arc-fault detection is one part of a coordinated protection system. Specify the exact device functions and request the relevant arc-fault and RCBO documentation. Installation, wiring condition and other protection requirements remain part of the project design.
No assumption should be made. The DC reference links operating voltage to pole configuration and wiring. Confirm the actual series connection, polarity, voltage and current for the selected product from the current technical file.
Protection ratings depend on the enclosure and installation. Select the actual product, cable entries, seals and door arrangement, then request the supporting rating information. Indoor metal boards, plastic boxes and industrial cabinets use different constructions.
Provide dimensions, installation, equipment schedule, single-line drawing, environment, cable entry, thermal needs and access requirements. State whether you need an empty enclosure or an equipped assembly, then agree documentation and acceptance tests for that scope.
Supply the breaker layout, pole sequence, terminal type, pitch, length, feed arrangement and current. Confirm end caps, insulation and enclosure conditions. A busbar described as compatible with various breakers still needs exact mechanical and electrical matching.
Submit the selected model and artwork, handle/casing colours, pack design and any technical changes for evaluation. Feasibility, testing, tooling and quantities should be agreed for that product. Approve the actual sample and final label content before bulk production.
Yes, include them in the enquiry with the required rating and destination. Confirm sample cost and timing in the quote, and request documents by actual model and scope. Standard names and generic certificate listings do not establish all-market product approval.
Send a SKU schedule with function, rating, poles, supply, quantities and destination; add drawings, packaging, artwork, required reports, inspection and service expectations. MOQ, production timing, freight and warranty conditions are confirmed for the selected order.
