Why Choose the ABB S203MTR-C1.6 Miniature Circuit Breaker?

The ABB S203MTR-C1.6 is a specialised three-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overload and short-circuit conditions in demanding railway, rolling-stock and traction applications. As part of ABB's traction circuit-protection range, it combines dependable protection with a compact modular format for transport electrical systems.

The S203MTR-C1.6 is intended for applications where reliable low-current circuit protection is required within railway electrical distribution, auxiliary power and control equipment. Its three-pole configuration provides coordinated circuit protection across three conductors, making it suitable for three-phase installations and other appropriate traction electrical circuits.

With a rated current of 1.6 A, a Type C tripping characteristic, 3P configuration and 10 kA short-circuit breaking capacity, the S203MTR-C1.6 provides effective protection for low-current circuits. The Type C characteristic is suitable for circuits with moderate starting and inrush currents while maintaining reliable overload and short-circuit protection.

Reliable Circuit Protection for Railway and Traction Systems

Miniature circuit breakers such as the ABB S203MTR-C1.6 automatically interrupt an electrical circuit when excessive current occurs because of an overload or short circuit. This helps protect cables, conductors and connected electrical equipment against potentially damaging fault currents while allowing the breaker to be reset after the cause of the fault has been identified and corrected.

The three-pole configuration makes the S203MTR-C1.6 suitable for coordinated protection across three conductors. Combined with its 1.6 A rating, Type C characteristic and traction-focused design, it provides a practical circuit-protection solution for low-current railway auxiliary, control and electrical distribution applications where moderate starting or inrush currents can occur.

Typical Applications

• Railway and rolling-stock electrical systems.
• Traction auxiliary electrical circuits.
• Low-current three-phase circuits.
• Train control and equipment cabinets.
• Railway distribution and protection panels.
• Auxiliary power and control circuits.
• Electrical loads with moderate starting or inrush currents.
