2CDS271565R0984 ABB S201MTR-C0.5 DC 0.5A 1P Type C 10kA DC Miniature Circuit Breaker

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

The ABB S201MTR-C0.5 DC is a compact single-pole DC miniature circuit breaker (MCB) designed to protect electrical circuits against overload and short-circuit conditions. With ABB order code 2CDS271565R0984, this device forms part of ABB's specialist DC / traction miniature circuit breaker portfolio for demanding industrial and transportation electrical systems.

Featuring a 0.5 A rated current, Type C tripping characteristic and 10 kA short-circuit rating, the S201MTR-C0.5 DC provides dependable protection for sensitive low-current DC circuits. The Type C characteristic accommodates moderate transient and inrush currents while maintaining effective protection against sustained overloads and short circuits.

Its compact 1-pole modular configuration makes the S201MTR-C0.5 DC suitable for installation in distribution assemblies and control panels where space-efficient DC circuit protection is required. The low 0.5 A rating makes it particularly useful for auxiliary, signalling, instrumentation and control circuits within industrial and traction-related electrical systems.

Reliable Protection for DC Electrical Circuits

Miniature circuit breakers such as the ABB S201MTR-C0.5 DC automatically interrupt excessive current caused by overload or short-circuit conditions. This helps protect conductors and connected electrical equipment from damaging overcurrents while providing resettable circuit protection once the cause of a fault has been identified and corrected.

The Type C characteristic provides a practical balance between sensitivity and tolerance of normal transient currents. This makes the S201MTR-C0.5 DC suitable for industrial control, auxiliary, instrumentation and equipment circuits where moderate switch-on or inrush currents may occur during normal operation.
