2CDS271565R0277 ABB S201MTR-K2 DC 2 A 1P Type K Miniature Circuit Breaker 10 kA

Why Choose the ABB S201MTR-K2 DC Miniature Circuit Breaker?

The ABB S201MTR-K2 DC is a specialised single-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection in DC and traction-related electrical systems. Part of ABB's S200 MTR family, this model combines a 2 A rated current, Type K tripping characteristic and 10 kA short-circuit breaking capacity in a compact modular device.

Its Type K characteristic is particularly suited to circuits containing loads with elevated starting or energisation currents, including motors, transformers, solenoids and other inductive equipment. This characteristic helps accommodate appropriate functional current peaks while maintaining effective protection against genuine overload and short-circuit conditions.

The S201MTR-K2 DC uses thermal-magnetic protection to respond to sustained overloads and short-circuit faults. Its 2 A rating, single-pole configuration and specialised K characteristic make it a practical protective device for low-current auxiliary, control and inductive-load circuits in industrial, transportation and traction-related electrical systems.

Reliable Protection for Inductive DC and Traction Circuits

The ABB S201MTR-K2 DC automatically disconnects the protected circuit when excessive current results from an overload or short circuit. Its thermal release responds to sustained overload conditions, while its magnetic release provides rapid interruption during short-circuit faults, helping protect conductors and connected equipment against damaging electrical and thermal stress.

The combination of a 2 A rating and Type K characteristic makes this breaker particularly useful for low-current circuits containing inductive loads or equipment that produces legitimate current peaks during energisation. Its 10 kA breaking capacity and S200 MTR construction provide a dependable solution for motor, transformer, solenoid, auxiliary and control circuits in industrial and transportation electrical systems.
