Match protection to the circuit. Coordinate the controls and enclosure.
Source fixed, adjustable and electronic circuit protection, motor switching, distribution boxes and matched accessories. Compare voltage-specific fault ratings, trip settings, mounting, packaging and technical-document requirements for each product.
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.
Feeder protection options include different frames, pole layouts and short-circuit performance levels. Select the actual operating voltage, rated current and trip arrangement for the circuit. Fixed thermal-magnetic protection can be coordinated with terminals, phase separators, panel mounting and optional operating accessories. Frame size and rated current should be recorded separately in the purchasing schedule.
Enquire about this range ↗Adjustable MCCB directions allow overload and instantaneous settings to be selected for the load and protection study. Thermal-only and thermal-plus-magnetic arrangements are separate options. Specify the adjustment range, rating plug or current reference, required fault performance and upstream/downstream coordination. Approval should use the exact trip-unit curve and setting instructions.
Enquire about this range ↗Electronic releases provide another protection direction for industrial feeders. Define the required overload, short-circuit and any additional protection functions, then compare the actual trip unit and adjustable settings. The available settings differ from thermal-magnetic products. Submit the load schedule, selectivity requirements and control or indication needs for technical matching.
Enquire about this range ↗Modular MCB directions cover different module widths, current selections, B/C/D characteristics and breaking-capacity versions. Confirm the voltage, poles, terminal arrangement and DIN-rail layout. Compare the actual Icn or other declared interruption rating at the relevant voltage. A high-capacity version should remain a distinct line item from a lower-capacity device in the same family.
Enquire about this range ↗Compact MCB and RCBO directions support distribution boards with limited module space. Specify whether neutral switching is required and confirm the actual internal pole arrangement, width and terminals. For RCBO enquiries, include residual-current sensitivity, waveform response and operating technology as well as the overcurrent specification.
Enquire about this range ↗DC breaker enquiries require the maximum circuit voltage, current, polarity and pole connection. Submit the source and load characteristics, including photovoltaic or battery conditions where relevant. Request the selected DC wiring diagram and interruption evidence. AC voltage or AC breaking figures should not be used to establish a DC rating.
Enquire about this range ↗RCCB directions include two-pole and four-pole arrangements across several constructions. Confirm rated current, residual-current response, sensitivity, delay and compatibility with separate overcurrent protection. Electronic and electromagnetic operating directions need individual selection. The waveform type and required operation under supply conditions should be part of the technical brief.
Enquire about this range ↗RCBO products combine circuit overload/short-circuit protection with a residual-current function. Compact and other modular constructions can be reviewed for the board layout. State poles, supply, curve, current and sensitivity. Confirm the specific residual-current type and supporting test evidence instead of treating every RCBO as having the same leakage response.
Enquire about this range ↗Residual-current MCCB directions suit feeder-level enquiries where overcurrent and earth-leakage functions are required together. Sensitivity and delay selections are tied to the actual frame and release. Provide the protection study and the required coordination with downstream devices. Different delay or threshold options must be confirmed in the selected order code.
Enquire about this range ↗Low-voltage ACB directions address main incomers and larger distribution circuits with electronic protection. Specify current, poles, fault performance, fixed or withdrawable arrangement and required controller functions. Enclosure protection depends on the mounting compartment, door frame and cover. The bare device and the completed switchboard should have separate scope and documentation.
Enquire about this range ↗Contactor enquiries can be matched to motor power, utilization category, operating voltage and coil supply. Include auxiliary contacts, duty cycle and coordination with the protective device. Motor power ratings are voltage- and duty-dependent. Additional thermal-overload relay requirements can be submitted with the starter brief for technical and availability review.
Enquire about this range ↗Adjustable motor-protection devices support matching overload settings to the motor current. Supply the nameplate current, motor voltage, starting method and coordination requirements. A motor power example at one voltage should not be used at another voltage. Confirm the specific operating mechanism, accessories and short-circuit coordination for the starter.
Enquire about this range ↗Single-pole isolator directions can be considered alongside the protection schedule. Specify the current, voltage, isolation function, utilization duty and mounting. A switching or isolation device needs separate overcurrent and residual-current protection where required by the installation design. Locking and indication requirements should be agreed for the selected construction.
Enquire about this range ↗Empty modular boxes include surface and flush mounting, plastic-base and iron-base directions, and several way counts. Select the rail, terminals, cover, door and cable-entry requirements. Indoor IP40 and smaller IP30 constructions are different products. Confirm whether the quotation is for the empty box, accessories or an equipped distribution board.
Enquire about this range ↗IP65 catalogue directions include different plastic constructions and module capacities. Provide the installation environment, number of ways, cable glands, terminal needs and mounting layout. Review the actual enclosure drawing and sealing arrangement. The rating must be supported for the supplied construction and cable-entry configuration; it is not a promise of performance in every outdoor condition.
Enquire about this range ↗Steel-base boxes with plastic cover options provide another surface or flush mounting direction. Define module arrangement, opaque or transparent cover, incoming cable details and finish requirements. Approve the actual dimensions and supplied hardware. Quotation and packing should identify the exact enclosure variant rather than relying on a family photograph.
Enquire about this range ↗L-, T- and straight-joint cover directions are listed in different voltage classes. Submit the busbar dimensions, joint form, phase spacing, installation conditions and required electrical evidence. Select the actual cover and shrink procedure. A catalogue voltage-class label does not by itself approve a completed busbar assembly or establish compliance for every application.
Enquire about this range ↗Accessories include plug-in and draw-out arrangements, rotary handles, motor operating mechanisms, shunt and undervoltage releases, auxiliary contacts and alarm contacts. State the host breaker, frame, contact function, control voltage and installation arrangement. Mechanical fit and electrical compatibility require confirmation for the exact combination. Specialist vacuum-breaker enquiries can be reviewed separately with the required voltage class and technical brief.
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.
Two interruption versions are listed for the same modular family. Select the actual current, poles and trip curve, with the required version recorded explicitly.
A wider modular construction with separate normal and higher interruption versions. Confirm the selected rating at the actual supply voltage.
A compact combined-protection direction. The residual-current sensitivity and waveform response must be specified with the quotation.
This S-version example keeps ultimate and service short-circuit ratings separate. Select the required current within the frame and confirm terminals and mounting.
An adjustable thermal-plus-magnetic direction for protection coordination. Settings apply to this construction rather than electronic releases.
The electronic family lists its own adjustment references. Request the selected frame, trip-unit functions and complete curve before approval.
A four-pole feeder-protection example with selectable residual-current thresholds and delays. Coordination must use the selected settings.
A main-distribution reference with separate voltage-dependent interruption figures. Enclosure ratings require the specified compartment and additional parts.
Motor switching capacity is specified at a particular voltage and utilization category. Select the actual contactor and coil for the motor.
This setting range is tied to a specific motor-protection reference. The motor-power example is conditional on the stated supply.
An empty plastic-base box direction. The listed carton is a packing reference for this exact surface-mount variant, subject to the agreed order pack.
A sealed empty-box direction with its own pack schedule. Specify entries, seals, terminals and installation before confirming the enclosure configuration.
Select the voltage class and joint geometry for the actual busbar installation. Request the corresponding dimensions and electrical documentation.
An accessory direction requiring an exact host-breaker match. The listed control supplies are alternatives rather than one universal coil.
References describe separate catalogue constructions and selected versions. Current, poles, interruption performance, residual-current response and enclosure protection must be confirmed together for the quoted item. Illustrations show product directions; equipped boards and empty enclosures require separate scope.
Focus the sourcing conversation on the features, materials and production details that make a difference to your product range.
A combined enquiry can cover modular and moulded-case protection, main air breakers and motor switching. Recording the intended load, fault level, trip requirements and installation keeps alternatives comparable. Accessories and boxes can be reviewed with the device schedule rather than added without a compatibility check.
Fixed, adjustable and electronic releases serve different selection needs. Include settings, control voltages, contact functions and operating mechanisms in the brief. This supports a clearer quotation and sample review, especially when the device must fit an existing panel or control arrangement.
Private-label or specification-development requirements can be submitted with artwork, drawings and the expected documentation. Agree sample acceptance, unit labels, language, pack contents and carton handling before production commitments. Model-specific packing references help plan consolidation without applying one carton schedule to every item.
Bring artwork, reference samples and a target cost. The available process, minimum quantity, sample charges and development scope are reviewed for the chosen option.
Submit your product specification, desired presentation and permitted artwork. Label layout, colour or construction changes need feasibility review for the selected device. Any technical change requires assessment of markings, test evidence and certification scope. Minimum quantities, development charges and tooling ownership are quoted for the actual project.
State the precise electrical version, accessories, mounting space and terminal needs when requesting samples. Review operation, dimensions, labels and supplied documents against the approved specification. Sample availability, charges and timing depend on the selected product and changes; agree them before relying on a programme date.
Specify individual-box contents, accessory bags, instructions, barcode placement and destination labels. Confirm carton quantity, gross weight and dimensions for each variant. Packing schedules differ between surface/flush boxes and between breaker frames. Agree any protective inserts, pallet plan or mixed-order consolidation in the quotation.
Agree which product characteristics need testing and how the approved sample relates to the bulk order.
Request product-specific evidence for trip limits, overload response, short-circuit performance and temperature rise as appropriate. For electronic products, define electromagnetic-compatibility and controller checks. Confirm the current, voltage, poles, settings and test conditions in the evidence; a general laboratory list is not an approval for every product.
Review enclosure moulding, metal parts, riveting or welding, terminal fastening and assembly against the agreed specification. Approve mechanical operation, mounting dimensions, accessory fit and cable-entry arrangements. For boxes and busbar covers, confirm the supplied construction and installation conditions supporting the requested protection.
Agree incoming-material records where needed, sampling, visual inspection, functional checks and label verification. Record the approved version and accessory combination so substitutions require review. Set the required batch identification, inspection report and acceptance criteria before order confirmation rather than assuming a universal testing or warranty package.
Test capability is a starting point for the inspection plan. Request the method, applicable model and results needed for your order.
Technical evidence should identify the exact item, rating and configuration. Tell us the destination and required approvals so document availability and scope can be reviewed before purchase.
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.
Submit the single-line diagram, incoming and outgoing circuits, fault levels and panel layout. Compare main and feeder protection with device width, terminals and mounting. Confirm whether your scope requires components, empty enclosures or an assembled board with separate assembly evidence.
Provide motor nameplates, supply, starting duty and control-circuit requirements. Match contactor duty, motor-protection settings, auxiliaries and release voltages. Existing-panel replacements require dimensions and wiring review rather than an assumption of cross-brand interchangeability.
Create a clear product matrix by current, poles, curve, sensitivity and performance version. Review pack sizes, language, barcode and technical-document needs for your market. Keep different construction and rating variants identifiable through samples, labels and ordering codes.
Samples, commercial terms and responsibilities are agreed for the project. Use the same product and packing specification when comparing quotations.

Practical answers about this sourcing direction, customization and the reference options. Your agreed specification and written quotation determine the actual order.
Send the supply voltage and frequency, AC or DC, current, poles, required trip characteristic and prospective fault level. Add residual-current requirements, installation space, terminals and destination. A drawing, load schedule or single-line diagram makes it easier to compare suitable options.
They describe different short-circuit performance references. Provide the value and standard required by the design. Each figure must be matched to the selected device and operating voltage; a family maximum or a figure at another voltage should not replace the required rating.
Fixed protection and adjustable releases have different selection and coordination requirements. Thermal-plus-magnetic and electronic versions also list different adjustment ranges. Request the exact trip-unit data and curves, then agree the rated current and settings with the project designer.
State RCCB, RCBO or residual-current MCCB, along with poles, current, sensitivity, time delay and waveform response. Include any requirement for supply-independent operation and coordination with upstream or downstream devices. The actual selected product and supporting evidence determine suitability.
Provide the complete DC voltage, current, source, polarity and wiring arrangement for a DC-specific review. Request the selected product’s DC rating and connection diagram. AC ratings alone do not establish a suitable DC interruption capability.
No. Motor power depends on supply voltage and utilization duty. Submit the motor current, voltage, starting method, operating frequency and coil supply. The contactor and motor-protection device should be selected and coordinated for that actual duty.
The listed enclosure directions are empty-box references unless the quotation explicitly includes devices and accessories. Specify the rail, terminal bars, cover, cable entries and component schedule. An equipped or tested board requires its own defined supply scope.
The completed installation must use the appropriate entries, glands, seals and mounting arrangement. Confirm the selected enclosure’s supporting evidence and instructions. The enclosure rating should not be assumed for an altered or differently assembled box.
Send the technical specification, presentation requirements and artwork for feasibility review. Agree samples, approval criteria, quantities and any development work. Technical changes can affect documentation and approval scope, so final arrangements are confirmed for the actual selected construction.
Provide the exact host, frame, mounting details and circuit diagram. Mechanical and electrical compatibility must be established for the specific combination. A similar outline or familiar family description does not establish interchangeability or authorization.
These are quoted for the selected product, quantity, current availability and customization. Provide your required delivery window and destination. Confirm sample charges, approval steps, packing and production timing in the order rather than applying one schedule to every range.
List the destination requirements, applicable standard, technical data, drawings and test or conformity evidence needed. Agree batch inspection, traceability, label review and packing checks. Document availability and any certification scope must be verified for the actual model and rating.
