Miniature circuit breakers – MCBs

Uncompromising safety and comfort

Miniature Circuit Breakers protect installations against overload and short-circuit, warranting reliability and safety for operations. System pro compact S 200 series are current limiting overcurrent protective devices. They have two different tripping mechanisms, the delayed thermal tripping mechanism for overload protection and the magnetic tripping mechanism for short circuit protection.

From 6A up to 63A in 1, 2 and 3 Poles

Main benefits
