Why Choose the ABB S202MTR-K63 Miniature Circuit Breaker?
The ABB S202MTR-K63 is a high-performance 2-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in demanding rolling stock, traction and industrial electrical applications. As part of the specialised ABB S 200 MTR series, it combines robust circuit protection with ring-tongue connections developed for secure electrical installations in railway environments.
This miniature circuit breaker features a Type K tripping characteristic, making it particularly suitable for circuits supplying equipment with relatively high starting or inrush currents. Its two-pole configuration provides simultaneous circuit protection across two conductors, while the S 200 MTR construction is engineered to withstand demanding vibration, shock and environmental conditions encountered in rolling stock.
With a rated current of 63 A and a 10 kA DC ultimate short-circuit breaking capacity, the S202MTR-K63 provides dependable protection for higher-current distribution and auxiliary circuits. For ratings above 25 A, the S 200 MTR range also provides an AC ultimate short-circuit breaking capacity of 15 kA according to IEC/EN 60947-2.

Reliable Circuit Protection for Rolling Stock and Traction Systems
Miniature circuit breakers such as the ABB S202MTR-K63 automatically interrupt a circuit when excessive current caused by an overload or short circuit occurs. This helps protect cables, connected equipment and electrical distribution systems from damaging fault currents while allowing the circuit breaker to be reset after the cause of the fault has been corrected.
The ABB S 200 MTR range is specifically developed for railway applications and combines high short-circuit performance with resistance to vibration, shock and extreme temperatures. Its Type K characteristic and secure ring-tongue connections make the S202MTR-K63 particularly suitable for demanding electrical circuits in rolling stock and traction equipment.
Typical Applications
- Railway rolling stock electrical systems.
- Traction electrical distribution equipment.
- Train auxiliary power circuits.
- Higher-current equipment protection.
- Circuits supplying loads with elevated starting currents.
- Protection of long-cable AC systems.
- DC electrical circuits with appropriate polarity configuration.
- Industrial transportation and automation equipment.
