Why Choose the ABB S202MTR-K8 Miniature Circuit Breaker?
The ABB S202MTR-K8 is a specialised two-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection in railway, rolling stock and traction electrical systems. Part of the ABB S200 MTR series, this model combines an 8 A rated current, Type K tripping characteristic and 10 kA rated short-circuit capacity.
The S200 MTR range is engineered for demanding railway electrical installations and provides protection for conductors and connected equipment against excessive current. The S202MTR-K8 uses thermal-magnetic protection and a two-pole configuration, allowing both poles to be disconnected when an overload or short-circuit condition requires circuit interruption.
Its Type K characteristic is particularly suitable for circuits supplying inductive loads and equipment that can produce increased starting currents, including motors, transformers and control equipment. Railway-oriented construction and secure ring-tongue connections make the S202MTR-K8 a practical choice for onboard auxiliary and equipment circuits, with ABB order code 2CDS272447R0407 identifying this exact model.

Reliable Protection for Railway and Inductive Loads
The ABB S202MTR-K8 protects electrical conductors and connected equipment against excessive current caused by overloads and short circuits. Its thermal protection responds to sustained overload conditions, while the magnetic mechanism provides rapid interruption when a high short-circuit current occurs.
The Type K characteristic allows the breaker to accommodate the increased starting currents associated with many inductive loads while maintaining effective fault protection. Combined with the railway-oriented S200 MTR construction and ring-tongue connection system, this makes the S202MTR-K8 well suited to demanding rolling stock control, auxiliary and equipment circuits.
