£22.42
The ABB S201-D2 is a premium single-pole miniature circuit breaker (MCB) engineered to provide dependable protection against overloads and short circuits in residential, commercial and industrial electrical installations. As part of the trusted ABB System pro M Compact S200 series, it combines reliable circuit protection with compact installation and long service life.
Featuring advanced thermal and electromagnetic tripping mechanisms, the S201-D2 protects electrical circuits by responding accurately to overload and fault conditions. Its compact modular design enables fast installation on standard DIN rails, while compatibility with ABB auxiliary accessories provides added flexibility for modern electrical systems.
With a 2 A rated current, D curve tripping characteristic and 6 kA breaking capacity, the ABB S201-D2 is particularly suited to protecting circuits supplying transformers, motors, control equipment and other devices with high inrush currents.
The ABB S201-D2 automatically disconnects electrical circuits when overload or short-circuit conditions occur, helping to protect wiring, equipment and connected devices from damage. Its dual thermal and magnetic tripping mechanisms provide dependable fault protection and reliable long-term performance.
The D curve characteristic is specifically intended for applications where equipment draws higher temporary starting currents. This makes the S201-D2 well suited to transformers, motors, magnetic coils and specialised industrial control equipment.
