Why Choose the ABB S203MTR-C8 Miniature Circuit Breaker?
The ABB S203MTR-C8 is a high-performance three-pole miniature circuit breaker (MCB) designed to provide reliable overcurrent protection for electrical circuits in demanding traction, rolling-stock and industrial applications. As part of the specialised ABB S200 MTR series, it combines a compact modular design with a Type C tripping characteristic and a rated current of 8 A.
Designed for circuits requiring dependable protection against overloads and short circuits, the S203MTR-C8 provides simultaneous three-pole protection in a compact DIN-rail format. Its Type C characteristic makes it suitable for circuits where moderate inrush currents may occur while maintaining effective protection of conductors and connected electrical equipment.
With a rated current of 8 A, three-pole configuration and 10 kA short-circuit breaking capacity, the S203MTR-C8 is suited to control, auxiliary and distribution circuits where robust circuit protection is required. ABB order code 2CDS273447R0084 uniquely identifies this configuration within the S200 MTR range.

Reliable Circuit Protection for Traction and Industrial Systems
Miniature circuit breakers such as the ABB S203MTR-C8 automatically interrupt a circuit when excessive current is caused by an overload or short circuit. This helps protect conductors, equipment and electrical installations from damage while allowing the circuit breaker to be reset after the fault has been identified and corrected.
The ABB S200 MTR family is developed for demanding electrical installations, particularly traction and rolling-stock systems. Its construction is designed to support the requirements of railway environments, while the S203MTR-C8 combines three-pole switching with a Type C characteristic for circuits that may experience moderate transient or starting currents during normal operation.
Typical Applications
- Rolling-stock and railway electrical systems.
- Traction auxiliary electrical circuits.
- Industrial control panels and distribution boards.
- Three-pole control and auxiliary circuits.
- Machine and automation electrical systems.
- Equipment protection and auxiliary power distribution.
