Description
The S202-C63 miniature circuit breaker from ABB’s System pro M compact S200 range delivers reliable circuit protection for residential, commercial, and industrial installations. It features both a delayed thermal tripping mechanism for overload protection and an electromechanical trip for short-circuit events, ensuring fast and precise fault detection. The Type C tripping curve makes it suitable for circuits with moderate inrush currents, including lighting, HVAC systems, and small machinery. Its compact two-pole modular design supports DIN-rail installation and optional bottom-fitting auxiliary contacts that save up to 50% space, offering flexibility and efficiency in modern electrical panels. For enhanced protection and system optimization, it integrates seamlessly into our industrial panel fabrication solutions.
