Description

The S202-C20 miniature circuit breaker from ABB’s System pro M compact S200 range provides precise protection for two-pole electrical systems in residential, commercial, and industrial installations. Featuring a dual tripping mechanism—thermal for overload protection and electromechanical for short-circuit protection—it ensures safe and efficient operation under all conditions. The Type C characteristic makes it ideal for circuits with moderate inrush currents such as lighting, motors, and power outlets. Compact, modular, and easy to install, the S202-C20 offers current-limiting performance and can be enhanced with bottom-mounted auxiliary contacts that save up to 50% space. For professional-grade integration, it can be used within our industrial panel fabrication systems.
