2CDS271565R0218 ABB S201MTR-Z1 DC 1A 1P Type Z 10kA DC Miniature Circuit Breaker

Why Choose the ABB S201MTR-Z1 DC Miniature Circuit Breaker?

The ABB S201MTR-Z1 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 2CDS271565R0218, this device forms part of ABB's specialist DC / traction miniature circuit breaker portfolio for demanding industrial and transportation electrical systems.

Featuring a 1 A rated current, Type Z tripping characteristic and 10 kA short-circuit rating, the S201MTR-Z1 DC provides sensitive overcurrent protection for low-current DC circuits. The Type Z characteristic offers rapid magnetic response, making it particularly suitable for electronic, semiconductor, control and instrumentation circuits where relatively low fault currents require prompt interruption.

Its compact 1-pole modular configuration makes the S201MTR-Z1 DC suitable for installation in distribution assemblies and control panels where space-efficient DC circuit protection is required. The 1 A rating and sensitive Z characteristic make it particularly useful for auxiliary, signalling, control and electronic circuits within industrial and traction-related electrical systems.

Sensitive Protection for Low-Current DC Circuits

Miniature circuit breakers such as the ABB S201MTR-Z1 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 Z characteristic provides sensitive instantaneous tripping and is particularly appropriate for circuits containing electronic and semiconductor components with limited tolerance for overcurrent. This makes the S201MTR-Z1 DC well suited to control, instrumentation and auxiliary systems requiring rapid response to electrical faults.
