Why Choose the ABB S201MTR-C50 Miniature Circuit Breaker?
The ABB S201MTR-C50 is a specialised miniature circuit breaker (MCB) designed for reliable overload and short-circuit protection in demanding railway, traction and rolling-stock electrical systems. Part of the ABB S200 MTR series, this single-pole circuit breaker combines a 50 A rated current, Type C tripping characteristic and 10 kA breaking capacity.
The S200 MTR range is engineered for the protection and control of circuits against overloads and short circuits, including long-cable AC systems. The range features a special ring-tongue connection and complies with IEC/EN 60947-2, with an ultimate short-circuit breaking capacity of 15 kA for AC applications and 10 kA for DC applications.
With its 50 A current rating and Type C characteristic, the S201MTR-C50 is suitable for higher-current distribution and auxiliary circuits where moderate temporary starting or inrush currents may occur. Railway-specific qualifications include R26/HL3 according to EN 45545 and Category 1 – Class A/B body-mounted classification according to IEC 61373.
