Why Choose the ABB S201MT-D10NA Miniature Circuit Breaker?
The ABB S201MT-D10NA is a specialist 1P+N miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short-circuits. Part of the ABB S200 MT series, it is developed for demanding railway, rolling-stock and traction electrical installations where dependable circuit protection and phase-and-neutral switching are required.
Featuring a 10 A rated current, Type D tripping characteristic and 10 kA breaking capacity, the S201MT-D10NA provides robust protection for circuits supplying equipment with comparatively high starting or inrush currents. The Type D characteristic helps prevent unwanted magnetic tripping during normal energisation of suitable inductive and high-inrush loads while retaining overload and short-circuit protection.
The 1P+N configuration combines overcurrent protection of the phase conductor with switching of the neutral conductor, allowing both conductors to be disconnected together. Its compact DIN-rail format makes the S201MT-D10NA well suited to auxiliary distribution, control equipment and other electrical circuits within railway, transportation and industrial systems.

Reliable Protection for High-Inrush Traction and Control Circuits
Miniature circuit breakers such as the ABB S201MT-D10NA 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 against damage while providing a resettable protective device that can be returned to service after the fault has been safely cleared.
The S201MT-D10NA combines a 10 A rating with a Type D characteristic, making it particularly appropriate for suitable circuits where high short-duration starting currents are expected. Its switched neutral and railway-oriented S200 MT construction provide a practical protection solution for auxiliary, control and equipment circuits in rolling-stock and other demanding electrical systems.
Typical Applications
- Railway and rolling-stock electrical systems.
- Traction auxiliary and control circuits.
- Circuits supplying loads with high short-duration inrush currents.
- Industrial control and automation panels.
- Phase-and-neutral circuit protection and isolation.
- Transportation equipment electrical distribution systems.
