Description
The S201-C50 miniature circuit breaker from ABB’s System pro M compact S200 series provides precise and dependable protection against overloads and short circuits. It combines a thermal tripping mechanism for overload protection with an electromechanical trip for short-circuit detection, ensuring safe, fast fault interruption. The Type C tripping curve makes it suitable for circuits with moderate inrush currents such as HVAC systems, lighting networks, and general distribution panels. Compact and modular, the S201-C50 allows for bottom-mounted auxiliary contacts that reduce panel space by up to 50%. For enhanced system integration and performance, it can be incorporated within our industrial panel fabrication assemblies.
