Why Choose the ABB S202MT-D2 Miniature Circuit Breaker?
The ABB S202MT-D2 is a high-performance 2-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding railway, traction and industrial electrical systems. As part of the specialised ABB S 200 MT series, it combines a 2 A rated current, Type D tripping characteristic and 10 kA breaking capacity in a compact modular format.
Developed specifically for traction applications, the S 200 MT range uses dedicated materials and construction suitable for demanding rolling-stock environments. Its design supports reliable operation where resistance to shock and vibration, stringent fire-safety requirements and dependable electrical protection are important.
With a rated current of 2 A and a 2-pole configuration, the S202MT-D2 is particularly suitable for low-current circuits supplying equipment with comparatively high starting or inrush currents. The Type D characteristic provides increased tolerance of momentary inrush currents, making the breaker useful for inductive and other high-inrush loads while retaining effective overload and short-circuit protection.
Key Advantages
- Specialised 2-pole miniature circuit breaker for traction applications.
- 2 A rated current suitable for low-current auxiliary and control circuits.
- Type D tripping characteristic suitable for equipment with high starting or inrush currents.
- 10 kA breaking capacity for robust short-circuit protection.

Reliable Circuit Protection for Railway and Industrial Systems
Miniature circuit breakers such as the ABB S202MT-D2 automatically disconnect an electrical circuit when an overload or short circuit occurs. This protects conductors and connected equipment against damaging overcurrents while allowing the breaker to be reset once the underlying electrical fault has been identified and corrected.
The Type D characteristic is designed for circuits where comparatively high transient starting currents can occur during normal operation. This makes the S202MT-D2 particularly useful for inductive equipment, transformers, solenoids and other loads where a more tolerant instantaneous trip characteristic helps prevent unwanted operation during normal energisation.
Typical Applications
- Railway and rolling-stock electrical systems.
- Traction auxiliary circuits.
- Low-current circuits with high inrush loads.
- Transformers and inductive electrical equipment.
- Industrial control and automation panels.
- Machine and equipment auxiliary circuits.
