2CDS271565R0024 ABB S201MTR-C2 DC 2 A 1P Type C Miniature Circuit Breaker 10 kA

Why Choose the ABB S201MTR-C2 DC Miniature Circuit Breaker?

The ABB S201MTR-C2 DC is a specialised single-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection in DC and traction-related electrical systems. Part of ABB's S200 MTR family, this model combines a 2 A rated current, Type C tripping characteristic and 10 kA short-circuit breaking capacity in a compact modular device.

Its Type C characteristic provides a practical balance between sensitive circuit protection and tolerance of moderate switching or starting currents. With its 2 A rating, the S201MTR-C2 DC is well suited to auxiliary, control, signalling and other low-current DC circuits where reliable protection of conductors and connected equipment is required.

The S201MTR-C2 DC uses thermal-magnetic protection to respond to both sustained overloads and short-circuit faults. Its single-pole configuration and modular construction make it a practical choice for industrial control equipment, transportation systems and traction-related electrical assemblies requiring compact and dependable circuit protection.

Reliable Protection for Low-Current DC and Traction Circuits

The ABB S201MTR-C2 DC automatically disconnects a protected circuit when excessive current results from an overload or short circuit. Its thermal release responds to sustained overload conditions, while its magnetic release provides rapid operation under short-circuit conditions, helping protect conductors and connected equipment from damaging electrical and thermal stress.

The combination of a 2 A rating and Type C characteristic makes this breaker particularly useful for low-current circuits that may experience moderate transient currents during normal switching. Its 10 kA breaking capacity and S200 MTR construction make it a practical solution for auxiliary, control and signalling circuits in industrial and transportation electrical systems.
