£21.48
The ABB S201-D20 is a premium single-pole miniature circuit breaker (MCB) designed 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 delivers reliable current limiting performance, compact installation and long service life for modern electrical distribution systems.
Engineered with advanced thermal and electromagnetic tripping mechanisms, the S201-D20 helps safeguard electrical circuits by responding accurately to overloads and fault currents. Its modular DIN rail design enables quick installation inside distribution boards and control panels, while compatibility with ABB auxiliary accessories provides additional flexibility for professional electrical installations.
Featuring a 20 A rated current, D curve tripping characteristic and 6 kA breaking capacity, the ABB S201-D20 is particularly suited to protecting circuits supplying motors, transformers, power supplies and other equipment with high inrush currents.
The ABB S201-D20 automatically disconnects electrical circuits when overload or short-circuit conditions occur, helping protect wiring, equipment and electrical systems from damage. Its combined thermal and magnetic tripping mechanisms provide dependable protection while maintaining reliable everyday operation.
The D curve characteristic allows the breaker to tolerate high temporary inrush currents before magnetic tripping occurs, making it particularly suitable for circuits supplying transformers, motors, solenoids and industrial machinery with demanding start-up characteristics.
