Description

The S201-C25 miniature circuit breaker from ABB’s System pro M compact S200 range provides precise and reliable circuit protection. Featuring both a delayed thermal tripping mechanism for overload protection and an electromechanical trip for short-circuit conditions, it ensures safe, consistent performance under all operating conditions. Its Type C characteristic makes it ideal for circuits with moderate inrush currents such as lighting, socket outlets, and small motor loads. Compact and modular, the S201-C25 allows bottom-mounted auxiliary contacts to save space while enhancing flexibility. For full system integration, it can be easily incorporated into our industrial panel fabrication systems.
