Description

The S201-C20 miniature circuit breaker from ABB’s System pro M compact S200 series provides reliable and precise protection for electrical installations. It uses two tripping mechanisms — a delayed thermal trip for overload protection and an electromechanical trip for short-circuit faults — ensuring fast response and high reliability. With a Type C characteristic curve, the S201-C20 is ideal for general-purpose circuits with moderate inrush currents, such as small motors and lighting systems. The compact, modular design saves space while maintaining consistent performance. For comprehensive electrical safety and optimized control setups, integrate it within our industrial panel fabrication systems.
