What matters for this category
A better brief.
A clearer comparison.
Focus the sourcing conversation on the features, materials and production details that make a difference to your product range.
Broader electrical procurement
Prepare a connected bill of materials across protective devices, control components, distribution enclosures and wiring hardware rather than collecting unrelated product names.
Specific technical comparisons
Keep trip curve, residual-current function, poles, duty category, coil and connector arrangement visible so quotations can be assessed against the application.
Useful supporting items
Include terminals, busbars, glands, ducts, tools and cabinet parts alongside the principal devices, with their own dimensional and inspection requirements.
Branding, configuration & packaging
Make the product
fit your programme.
Bring artwork, reference samples and a target cost. The available process, minimum quantity, sample charges and development scope are reviewed for the chosen option.
Device selection and interfaces
Provide the electrical schedule, contact chart, coil voltage, poles, curves, sensitivity, terminals and mounting. Request a current exact-item sheet and approved drawing.
Assembly and project scope
Submit enclosure layout, busbar arrangement, protection coordination, inlets/outlets and wiring diagrams. PV, medium-voltage or transfer-system requirements need separate engineering schedules.
Markings, samples and packing
Request artwork, labels, sample quantities, cartons and protective packing against the selected item. Tooling, minimum quantities, sample charges and production timing are confirmed in writing.
Quality & product evidence
Turn requirements
into checks.
Agree which product characteristics need testing and how the approved sample relates to the bulk order.
Confirm offered-model evidence
Request current reports and declarations matching the actual configuration, producer and destination. Historical catalogue standard references or corporate certificates do not establish current approval.
Agree inspection by family
Define breaker/protection tests, contactor or switch functions, timer settings, dimensional checks, terminal connections and enclosure inspection as applicable.
Check the complete installation
Review protection coordination, mating interfaces, conductor sizes, mounting and circuit drawings. Individual component ratings do not establish approval of the finished distribution assembly.
Test capability is a starting point for the inspection plan. Request the method, applicable model and results needed for your order.
Documents matched to the order
Ask for evidence
that fits the product.
Request a current product-specific technical and acceptance file. Specifications and reports must identify the exact offered configuration, with particular care for residual-current devices, DC switching and medium-voltage equipment.
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 ↗- Technical selection file
- Current device data sheets, electrical schedule, trip/contact diagrams, mounting dimensions, enclosure drawings and connection details.
- Testing and conformity file
- Applicable exact-model reports, declarations, agreed inspection criteria and destination-specific approval evidence with its current validity and scope.
- Commercial and logistics file
- Itemised quotation, sample/tooling terms, confirmed minimum quantities and timing, packing, marking, weights and shipment documents.

Buyer questions
Before you send
your first enquiry.
Practical answers about this sourcing direction, customization and the reference options. Your agreed specification and written quotation determine the actual order.
Which protection devices can be included?
Miniature, moulded-case and air breakers, residual-current devices, combined protection, fuses and surge-protection directions can be assessed against the required duty. State the exact voltage, current, poles and protection functions.
Are an RCCB and an RCBO interchangeable?
Identify whether overcurrent protection is required in addition to residual-current operation. Waveform type, sensitivity, neutral arrangement and breaking or conditional duty must match the offered device.
Can contactors and starters be supplied as a coordinated brief?
Provide the motor/load, utilisation duty, control voltage, overload range, reset and enclosure. The contactor, relay and short-circuit device need appropriate coordination.
Can I include terminals, busbars and boxes?
Include conductor sizes, device layout, interfaces, dimensions and environmental duty. Specify wiring, connection and inspection requirements for the complete assembly.
Are catalogue certifications current for every item?
Request current documents matching the exact article, ratings, producer and destination. Company certificates, old catalogue standards and printed approval marks do not replace model-specific evidence.
Can you review special transfer or high-voltage requirements?
Provide the complete engineering schedule for load/knife switching, automatic transfer, vacuum breakers or current-limiting fuses. Current model availability, duty and documentation require separate confirmation.
Can I request private marking, samples and a mixed range?
Send the item list, artwork, quantities, sample tests and packing needs. Feasibility, minimum quantities, charges, tooling and current production timing are confirmed for the selected products.
What should I send to obtain comparable quotations?
Send the itemised circuit schedule, voltage/current and protection duties, drawings or contact charts, standards and documents required, quantities, packing and shipment destination.
Who handles my enquiry?
Factory Sourcing Hub handles this enquiry as an independent sourcing and trading service. The product route, supplier suitability, sample scope and order responsibilities are agreed for the actual project.
How do I get a price and order minimum?
Send the product reference, quantities per variation, customization and packaging. Prices, minimums, sample charges and delivery dates are confirmed in a current quotation; the page is not a live inventory or price feed.
Can I discuss samples and inspection before ordering?
Yes. State whether you need a reference sample, a customized sample or development work. Agree the sample cost and shipping, approval specification, inspection plan and remedy for non-conforming goods before the bulk order.
What should I attach to my email?
Reference images, drawings, logo artwork and a product list are useful. Include quantities, the intended users and sales market, packaging, required documents and timing. After submitting the form, email attachments to kunhuow@gmail.com with your enquiry reference.
