IMO IEC (Non UL) Miniature Circuit Breakers

International Electrotechnical Commission (IEC)

Designed for optimum protection against overload and short circuits, IMO’s range of Mini Circuit Breakers (MCBs) help bridge the gap in electrical installations. IMO MCBs are available in 1P, 1P+N, 2P, 3P and 3P+N, with current range from 1A to 63A. These MCBs also ensure breaker tripping safety with 10kA short circuit breaking capacity.

All IMO MCBs are RoHS 2 compliant and a number carry the following approvals: CE; VDE; Kema Keur; GOST; RCM. Available accessories include: auxiliary switches, Shunt Trip, busbars and locking devices.
