Description
The S203-C25 miniature circuit breaker from ABB’s System pro M compact S200 range provides reliable and precise protection for three-phase electrical systems. It features a dual tripping mechanism — a thermal trip for overload conditions and an electromechanical trip for short-circuit faults — ensuring comprehensive safety and efficiency. With its Type C characteristic curve, the S203-C25 is well-suited for circuits with moderate inrush currents such as lighting systems, HVAC units, and small motor loads. The 3-pole configuration guarantees full phase isolation, while the compact modular design supports DIN-rail installation and bottom-fitting auxiliary contacts to save up to 50% panel space. For full system integration and professional-grade installations, it complements our industrial panel fabrication solutions.
