ABB S203P-D0.5 three-pole miniature circuit breaker with 0.5 A rated current and D curve tripping characteristic for reliable overload and short-circuit protection in industrial and commercial installations.
The ABB S203P-D0.5 is a premium three-pole miniature circuit breaker from the ABB System pro M compact S200P series, designed to provide reliable overload and short-circuit protection in commercial and industrial electrical installations. Featuring a 0.5 A rated current and a D-curve tripping characteristic, it is ideal for specialised low-current circuits with high inrush currents, including control transformers, instrumentation and inductive loads.
The S200P range incorporates advanced current-limiting technology to minimise fault energy and help protect downstream equipment. Separate thermal and electromechanical tripping mechanisms provide dependable overload and short-circuit protection while ensuring long service life and reliable operation.
With its three-pole configuration, compact modular construction and DIN rail mounting, the S203P-D0.5 is well suited for industrial control panels, machinery and automation systems requiring precise low-current protection.
The ABB S203P-D0.5 automatically disconnects electrical circuits during overload or short-circuit conditions, helping to protect sensitive equipment, wiring and electrical installations. Its D-curve characteristic allows higher short-duration starting currents without unnecessary tripping, making it suitable for specialised inductive applications.
Designed to comply with recognised international standards, the S200P series delivers dependable performance across industrial automation, OEM machinery and commercial electrical installations. Its modular construction also supports easy integration with ABB signalling and auxiliary accessories.
