Description

The S202-C50 miniature circuit breaker from ABB’s System pro M compact S200 series ensures precise and dependable circuit protection in demanding environments. It integrates two tripping mechanisms — a delayed thermal trip for overload protection and an electromechanical trip for short-circuit faults — to deliver comprehensive safety. With a Type C tripping curve, the S202-C50 is ideal for circuits with moderate inrush currents such as motors, HVAC systems, and lighting networks. The compact two-pole design allows complete isolation, while optional bottom-fitting auxiliary contacts save up to 50% space within enclosures. For complete integration and optimized performance, it can be used as part of our industrial panel fabrication solutions.
