Why Choose the ABB S201MTR-C0.5 Miniature Circuit Breaker?

The ABB S201MTR-C0.5 is a specialised miniature circuit breaker (MCB) designed for protection and control of electrical circuits against overloads and short circuits in demanding railway, rolling stock and traction applications. As part of the ABB S200 MTR series, it combines dependable circuit protection with a compact single-pole design and a special ring-tongue connection system.

The S201MTR-C0.5 features a Type C tripping characteristic and a rated current of 0.5 A. The S200 MTR C-characteristic range provides an ultimate short-circuit breaking capacity (Icu) of 15 kA for AC applications and 10 kA for DC applications according to IEC/EN 60947-2, providing robust fault protection for low-current circuits in demanding rolling stock electrical systems.

With its single-pole configuration, railway-focused construction and secure ring-tongue connection, the S201MTR-C0.5 is particularly suited to auxiliary, control and signalling circuits requiring a low current rating. The S200 MTR range is also suitable for the protection of long cables in AC systems and is designed to meet demanding railway requirements for fire behaviour, shock and vibration resistance.

Reliable Circuit Protection for Rolling Stock Systems

Miniature circuit breakers such as the ABB S201MTR-C0.5 automatically interrupt a circuit when excessive current results from an overload or short circuit. This helps protect cables, conductors and connected electrical equipment while allowing the circuit breaker to be reset after the electrical fault has been identified and corrected.

The ABB S200 MTR C-characteristic range is developed for demanding rolling stock installations. Its combination of high short-circuit performance, Type C tripping behaviour, specialised ring-tongue connections and railway-specific fire, shock and vibration classifications makes the S201MTR-C0.5 particularly suitable for dependable protection of low-current circuits within rail vehicle electrical systems.

Typical Applications

• Railway and rolling stock electrical systems.
• Low-current traction auxiliary circuits.
• Control, monitoring and signalling circuits.
• Protection of long cables in AC systems.
• Rolling stock distribution and control assemblies.
• Electrical circuits requiring Type C overload and short-circuit protection.
