OEM MCB ordering questions.
Confirm the exact series, rating and destination whenever requirements differ by model or market.
Does VIOX support OEM and private-label MCB orders?
VIOX can discuss logo, product marking, label content and packaging requirements for an OEM order. The available scope, quantity and approval path must be confirmed for the selected series during quotation.
Which information should I send for an MCB quotation?
Send the destination market, application, preferred series, rated current, voltage, pole configuration, trip curve, breaking-capacity requirement, quantity, branding needs and required documents.
Are certificates and standards the same for every MCB series?
No. Standards, declarations, certificates and reports must be checked against the exact product series, rating and destination market.
Can a sample be reviewed before a bulk order?
Include the sample requirement in the RFQ so the selected model, marking, packaging and required review documents can be aligned before production release.
How should a repeat MCB order be identified?
Reference the approved series, model, rating, artwork and packaging version. This keeps later replenishment tied to the same reviewed order scope.
Select the MCB. Approve the order. Keep repeat supply consistent.
Send your ratings, quantity, destination and OEM requirements for review.
