Import Circuit Breakers — Buy in Bulk from Supplier in China

These circuit breakers are rated for continuous current between 5A and 20A, with operational voltage compatibility from 12V to 250V AC or DC. They are designed for single-pole and double-pole configurations, suitable for low-voltage distribution panels in residential and light commercial settings. The trip mechanism is thermal-magnetic, providing protection against both sustained overloads and sudden short circuits.

The housing is constructed from flame-retardant thermoplastic, meeting UL 94 V-0 standards for fire resistance. Internal contacts are made of silver alloy, offering low contact resistance and extended cycle life. These are standard miniature circuit breakers, commonly referred to as MCBs, and align with IEC 60898-1 for household and similar installations. Typical breaking capacity is 6kA, which is standard for this current range in non-industrial applications.

Buyers include electrical contractors, building material distributors, and small-scale panel manufacturers sourcing for local markets. Packaging is in bulk cartons of 50 to 100 units, with each breaker individually wrapped in anti-static foam. Trade terms typically include FOB Ningbo or EXW from Cixi, with lead times of 15 to 25 days after order confirmation. MOQ is generally 100 units, but smaller trial orders may be accommodated upon request.
