Why Choose the ABB S204MT-C50UC Miniature Circuit Breaker?

The ABB S204MT-C50UC is a four-pole miniature circuit breaker (MCB) designed for reliable overload and short-circuit protection in AC and DC electrical systems, with particular suitability for traction and railway applications. As part of the ABB System pro M compact S200MT series, it combines a C tripping characteristic with universal-current capability for demanding rolling-stock and industrial electrical installations.

This circuit breaker provides dependable protection and switching of electrical circuits while supporting both alternating-current and direct-current applications. The UC version is designed for universal-current operation, making it suitable for electrical systems where AC and DC circuit protection requirements need to be accommodated within the same product family.

With a rated current of 50 A, a 10 kA rated breaking capacity and four poles, the S204MT-C50UC is suitable for protecting and controlling electrical circuits in railway, traction and associated distribution and control equipment. Its DIN-rail mounting format enables straightforward installation within compatible electrical assemblies.
