Description
The S202-C25 miniature circuit breaker from ABB’s System pro M compact S200 series delivers reliable and precise protection for electrical circuits. With both thermal and electromechanical tripping mechanisms, it ensures dependable protection from overloads and short circuits. The Type C characteristic curve makes it suitable for circuits with moderate inrush currents, such as lighting, HVAC, and small motors. Its compact two-pole design offers enhanced isolation and safety, while bottom-fitting auxiliary contacts can be mounted to reduce installation space by up to 50%. For complete system integration, use it alongside our industrial panel fabrication solutions for professional-grade electrical assemblies.
