Description

The S202-C40 miniature circuit breaker from ABB’s System pro M compact S200 range offers superior circuit protection through its dual tripping mechanism — a delayed thermal trip for overload conditions and an electromechanical trip for short-circuit events. Designed for circuits with moderate inrush currents, its Type C tripping curve makes it suitable for general power distribution, HVAC, and lighting systems. The 2-pole modular design ensures full isolation and reliability in both residential and industrial environments. Bottom-fitting auxiliary contacts can be added to optimize space usage, reducing panel size by up to 50%. For advanced integration, the S202-C40 can be incorporated into our industrial panel fabrication solutions for complete system protection.
