Molded case circuit breakers are ideally suited for coordinated solutions in infrastructure and industrial applications.

Miniature circuit breakers offer effective protection through safe disconnection in the event of an overload and short-circuit.

The motor starter protectors/circuit breakers are used for switching and protecting three-phase motors up to 37 kW at 400 V AC and for other loads with rated currents of up to 80 A.

SIRIUS overload relays with screw-type, spring-loaded or ring cable lug connections reliably protect loads as well as other switching and protective devices in the respective load feeder against overload, phase asymmetry and phase failure.

RCCB SIGRES has built-in condensation protection to ensure maximum safety and durability even under harsh conditions, such as gas or moisture in the ambient air.
