ABB S203P-D1.6 miniature circuit breaker from the S200P series, a three-pole 1.6 A D-curve MCB designed for reliable overload and short-circuit protection in industrial and commercial electrical installations.
The ABB S203P-D1.6 is a high-performance three-pole miniature circuit breaker from the ABB System pro M compact S200P series, designed to provide dependable overload and short-circuit protection in industrial and commercial electrical installations. With a 1.6 A rated current and D-curve tripping characteristic, it is suitable for circuits with high short-duration inrush currents.
The S200P range uses current-limiting technology to help reduce fault energy and improve protection for downstream electrical equipment. It combines delayed thermal overload protection with electromechanical short-circuit protection, supporting safe and reliable operation in low voltage distribution and control systems.
With a three-pole configuration, compact modular construction and DIN rail mounting, the S203P-D1.6 is well suited for control panels, machinery circuits and specialist three-phase installations requiring low-current protection with a D-curve response.
Miniature circuit breakers such as the ABB S203P-D1.6 automatically disconnect electrical circuits when overload or short-circuit faults occur. The D-curve characteristic allows the device to tolerate higher instantaneous inrush currents, making it suitable for selected inductive and control applications where nuisance tripping must be avoided.
The S200P series is widely used by electrical engineers and panel builders where compact installation, dependable protection and recognised international standards are required. Its DIN rail format allows straightforward integration alongside other ABB low voltage protection and control devices.
