What is the minimum order quantity for your circuit breakers?

Standard MCB, MCCB and SPD models start from 5 pieces per model, and air circuit breakers start from 1 piece, so buyers can test samples before scaling up to container orders.

Do you offer OEM and ODM services?

Yes. We support private labelling, laser-marked logos, customised ratings, packaging and multilingual manuals. Send your drawings or specification sheet to info@graybarelectrics.com for a technical review.

Which standards are your products designed to?

Products are designed with reference to IEC standards: IEC 60898-1 for MCBs, IEC 60947-2 for MCCBs and ACBs, IEC 61643-11 for surge protective devices, IEC 60947-6-1 for transfer switching equipment and IEC 60947-4-1 for contactors. Available certificates and test reports can be requested per model.

What is the difference between a draw-out and a fixed type air circuit breaker?

A draw-out ACB sits in a cradle and can be racked out for inspection or replacement without disconnecting busbars, reducing downtime in critical switchboards. A fixed type ACB is bolted directly to the busbars, which is more compact and economical where maintenance windows are acceptable.

Should I choose a single phase or 3 phase surge protection device?

Match the SPD to the supply system: single phase (1P+N) units protect residential and light commercial 230V boards, while 3 phase (3P or 3P+N) units protect 400V distribution and industrial panels. Earthing system (TN-C, TN-S, TT) also determines the pole configuration.
