Why Choose the ABB S201MT-C40 Miniature Circuit Breaker?

The ABB S201MT-C40 is a compact and dependable single pole miniature circuit breaker (MCB) from the ABB System pro M compact S200MT series. Designed especially for traction, railway and demanding industrial applications, this 40 A C curve MCB provides reliable overload and short circuit protection where robust performance and compact installation are required.

The S201MT-C40 uses ABB’s current limiting technology with a delayed thermal tripping mechanism for overload protection and an electromechanical tripping mechanism for short circuit protection. This helps reduce fault energy during short circuit events while supporting safe, consistent operation in electrical distribution and control systems.

With a 40 A rated current, C tripping characteristic and 10 kA breaking capacity, the ABB S201MT-C40 is ideal for railway electrical systems, distribution boards, control panels, auxiliary circuits and equipment with moderate inrush currents. Its compact DIN rail mounting format enables straightforward installation inside switchboards, electrical enclosures and industrial control cabinets.
