Qualify the supplier through the work itself.
A credible factory review connects each stage to a buyer decision: product consistency, functional verification and repeat-order identification.
Assembly follows a defined product family.
Confirm the selected MCB series, configuration and order marking before production. This keeps the quoted model, physical product and repeat order aligned.
Testing belongs to the model—not to a slogan.
Required checks and supporting documents should be reviewed against the exact series, rating and target-market requirement during quotation and sample confirmation.
Labels, packaging and model identity close the loop.
Model verification and approved artwork help distributors and OEM brands maintain consistent product identity across the first shipment and later replenishment.
OEM MCB supply with a controlled approval path.
The useful question is not simply whether private label is available. Buyers need to know what gets confirmed before production and what stays controlled for repeat orders.
Define the target market and MCB family
Share destination, application, pole configuration, rated current, trip curve, breaking-capacity expectation and quantity.
Align model, marking and packaging
Review the selected series together with logo placement, product marking, label content, inner box and carton requirements.
Confirm samples and documents
Check the physical sample, artwork and the model-specific technical documents required for the buyer’s review.
Release production against the approved scope
Keep the approved model, rating, artwork, packaging and commercial scope connected to the production order.
Control the repeat order
Reference the approved series and version so later replenishment does not restart with an ambiguous product description.
Ask for documents by series and order.
The correct document package depends on the product family, configuration and target market. Define what your technical team needs to review.
Product datasheet
Model ratings, dimensions and applicable technical information for the selected series.
Series document scope
Standards, declarations, certificates or reports should be checked against the exact model.
Label artwork approval
Confirm model name, ratings, brand marking and other approved label content before production.
Packaging approval
Align inner packaging, carton presentation and identification for standard or branded supply.
Confirmação de amostra
Record the model and configuration reviewed before a larger order is released.
Repeat-order reference
Preserve the approved series, artwork and packaging version for replenishment discussions.
Turn your requirement into a quote-ready MCB brief.
A complete RFQ reduces model ambiguity and helps VIOX return a more relevant series recommendation.

Prepare the information above, then open the VIOX inquiry form. Your message will reach the existing support workflow.
Request an MCB quote Final model, document and commercial scope are confirmed during quotation.Questions buyers ask before an MCB order.
Exact technical and certification details remain series-specific.
Does VIOX support OEM and private-label MCB orders?
VIOX can discuss logo, marking, packaging and related document requirements for OEM supply. The available scope, quantity and approval process should be confirmed for the selected series during quotation.
Which information should I send for an MCB quotation?
Send the target country, application, pole configuration, rated current, voltage, trip curve, breaking-capacity expectation, required standards or documents, branding needs and estimated quantity.
Are certificates and standards the same for every MCB series?
No blanket assumption should be made. Standards, declarations, certificates and reports must be checked against the exact product series, model and target market.
Can I review a sample before a bulk order?
Include the sample requirement in the RFQ so the model, marking, packaging and required review documents can be aligned before a larger order.
How should a repeat order be identified?
Reference the approved product series, model, rating, artwork and packaging version. This reduces the risk of repeating an order from an incomplete description.
