Why Choose the ABB S202MT-B6UC Miniature Circuit Breaker?
The ABB S202MT-B6UC is a high-performance 2-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in demanding AC and DC installations. Part of the ABB System pro M compact S200 MT UC series, it is specifically suited to industrial and rolling-stock applications requiring dependable universal-current circuit protection.
Featuring a 6 A rated current, Type B tripping characteristic and 10 kA ultimate short-circuit breaking capacity, the S202MT-B6UC provides responsive protection for circuits with comparatively low inrush currents. This makes it well suited to auxiliary, control, resistive-load and distribution circuits where rapid magnetic fault protection is required.
The two-pole configuration supports DC installations up to 440 V DC when connected with the specified polarity. The S200 MT UC range is also engineered for transportation environments, with ABB specifying R26/HL3 according to EN 45545 and Category 1, Class A/B according to IEC 61373, making it particularly suitable for railway and rolling-stock electrical systems.

Reliable Protection for Industrial and Rolling-Stock Circuits
Miniature circuit breakers such as the ABB S202MT-B6UC protect conductors and connected electrical equipment against excessive current caused by overload and short-circuit conditions. The Type B characteristic provides responsive magnetic fault protection for circuits that do not normally experience high starting currents, making it suitable for many auxiliary, control and resistive-load applications.
The S200 MT UC platform extends this protection to demanding transportation installations. Its capability for DC circuits up to 440 V DC in a two-pole arrangement, together with railway-specific fire, shock and vibration classifications, makes the S202MT-B6UC particularly suitable for rolling stock, traction auxiliaries and industrial systems requiring robust universal-current protection.
Typical Applications
- Railway and rolling-stock electrical systems.
- Traction auxiliary and control circuits.
- Industrial automation and control systems.
- AC and DC electrical distribution circuits.
- Long cable circuits in TN and IT systems.
- Industrial control and distribution panels.
- Low-inrush circuits requiring Type B protection.
