Gewiss Magnetothermal Circuit Breaker 25A 4P 6KA C 4 Modules GW92089

Curve C can tolerate short-term overcurrents of up to five to ten times the rated current and is widely used in domestic systems.

A circuit breaker is a safety device that can automatically (i.e., without external intervention) interrupt the flow of electric current in an electrical circuit in the event of an overcurrent.

The MCB Series 90 meets any requirement for overload and short-circuit protection, for all civil, tertiary and industrial applications. The range consists of MTC, compact circuit breakers (2 to 32A, curves B and C up to 10kA) MT traditional circuit breakers (1 to 63A, curves B, C and D up to 25kA) MTHP high performance circuit breakers (20 to 125A, curves C and D up to 25kA).
