Mini Circuit Breakers

We offer several lines of Miniature circuit breakers from Square D, Phoenix Contact, and ABB. MCBs are available as complete units that can be DIN rail mounted, or as plug-in units with bases.

Miniature circuit breakers (MCB) are compact circuit breakers with low current ratings and fixed trip settings used to switch and protect the lowest common distribution voltage in an electrical system. MCBs are available as complete units, or as plug-in units with bases.

Miniature circuit breakers may be simple breakers without a UL listing, or supplementary circuit breakers (UL 489 listed, UL 1077 recognized, or UL 2367 recognized to protect single devices), or branch circuit breakers (UL 489 listed to protect single or multiple devices).
