Why Choose the ABB S201MT-D3 Miniature Circuit Breaker?
The ABB S201MT-D3 is a specialised single-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overload and short-circuit conditions. Part of the ABB S200 MT series, it is engineered for demanding electrical installations, including industrial, railway and traction applications where reliable circuit protection is essential.
Featuring a Type D tripping characteristic, the S201MT-D3 is particularly suitable for circuits supplying equipment with high starting or inrush currents. Its 3 A rated current and 10 kA short-circuit breaking capacity provide dependable protection for low-current circuits while accommodating the transient currents associated with suitable inductive and high-inrush loads.
The compact single-pole construction enables efficient integration into control panels, distribution assemblies and transportation electrical systems. DIN rail mounting and the robust S200 MT platform make the S201MT-D3 a practical solution for protecting auxiliary, control and equipment circuits in demanding industrial and traction environments.

Reliable Circuit Protection for Industrial and Traction Systems
Miniature circuit breakers such as the ABB S201MT-D3 automatically disconnect an electrical circuit when excessive current occurs because of an overload or short circuit. The thermal element provides overload protection, while the magnetic mechanism responds rapidly to severe fault currents, helping protect conductors and connected equipment from electrical damage.
The Type D characteristic provides increased tolerance of short-duration inrush currents compared with more sensitive trip curves. This makes the S201MT-D3 particularly useful for suitable circuits containing transformers, solenoids, motors and other equipment that can produce significant current peaks during energisation or starting.
Typical Applications
- Railway and rolling-stock electrical systems.
- Traction and transportation equipment.
- Industrial control panels and switchboards.
- Transformer and solenoid circuits.
- Motor and other high-inrush-load circuits.
- Auxiliary and machine control systems.
