Description

The S201-C40 miniature circuit breaker from ABB’s System pro M compact S200 series offers high-performance circuit protection in a space-saving design. It features a delayed thermal tripping mechanism for overload protection and an electromechanical tripping mechanism for short-circuit conditions, ensuring fast and reliable fault clearance. With its Type C characteristic, the S201-C40 is ideal for circuits with moderate inrush currents such as lighting, HVAC, and control systems. Its modular structure allows easy DIN-rail installation, and optional bottom-mounted auxiliary contacts help reduce panel space by up to 50%. For optimized safety and system efficiency, integrate it within our industrial panel fabrication solutions.
