Why Choose the ABB S202MT-K63UC Miniature Circuit Breaker?
The ABB S202MT-K63UC is a high-performance 2-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in demanding industrial, DC and traction applications. As part of the specialised ABB S 200 MT UC series, it combines a 63 A rated current, Type K tripping characteristic and AC/DC capability for dependable circuit protection.
Developed for demanding electrical installations, the S202MT-K63UC is particularly suited to railway rolling stock, traction equipment, industrial machinery and control systems. The S 200 MT UC range provides high short-circuit breaking capacity and flexible use in AC and DC circuits, while its compact modular construction enables straightforward integration into distribution boards and electrical control panels.
With a rated current of 63 A, 2 protected poles and a short-circuit breaking capacity of 10 kA, the S202MT-K63UC provides robust protection for higher-current circuits and equipment with elevated starting currents. Its Type K characteristic makes it particularly suitable for inductive loads such as motors and transformers where normal inrush currents must be accommodated without unnecessary tripping.

Reliable Circuit Protection for Industrial and Traction Systems
Miniature circuit breakers such as the ABB S202MT-K63UC automatically disconnect an electrical circuit when excessive current occurs because of an overload or short circuit. This protects cables, conductors and connected equipment against damaging fault currents while allowing the breaker to be reset once the underlying electrical fault has been identified and corrected.
The Type K characteristic is particularly useful for circuits supplying inductive equipment with elevated starting currents. Combined with the AC/DC capability and robust S 200 MT UC platform, this makes the S202MT-K63UC well suited to motors, transformers, industrial control equipment, railway rolling stock and traction auxiliary systems.
Typical Applications
- Railway and rolling-stock electrical systems.
- DC traction auxiliary circuits.
- Industrial AC and DC distribution systems.
- Motor and transformer protection circuits.
- Industrial control and automation panels.
- Electrical distribution boards and machine control systems.
