Description
The S203-C10 miniature circuit breaker from ABB’s System pro M compact S200 series offers high-performance protection for three-phase electrical systems. Equipped with a delayed thermal tripping mechanism for overload protection and an electromechanical trip for short-circuit detection, it ensures accurate and dependable circuit interruption. The Type C tripping curve allows it to handle circuits with moderate inrush currents, such as lighting, HVAC, and control panels. The 3-pole design provides full phase isolation, making it ideal for industrial and commercial applications. Compact and modular, the S203-C10 allows for easy DIN-rail installation, with bottom-fitting auxiliary contacts that can save up to 50% of space. For seamless integration, it complements our industrial panel fabrication systems for enhanced safety and efficiency.
