ABB S203P-B16 three-pole 16 A B curve miniature circuit breaker from the System pro M compact S200P series, designed for overload and short circuit protection in industrial and commercial electrical installations.
The ABB S203P-B16 is a high performance three-pole miniature circuit breaker (MCB) designed to provide reliable protection against overloads and short circuits in commercial, industrial and OEM electrical installations. As part of the trusted ABB System pro M compact S200P series, it offers dependable circuit protection in a compact DIN rail mounted design.
This miniature circuit breaker features a B trip characteristic, making it suitable for circuits with low inrush currents such as lighting circuits, control circuits and general power distribution applications. Its current limiting design helps reduce fault energy during short circuit conditions, supporting safer operation and helping protect connected equipment and wiring.
With a rated current of 16 A, a three-pole configuration and a high breaking capacity of up to 25 kA, the ABB S203P-B16 is ideal for professional three-phase circuit protection applications. It is engineered for use in distribution boards, switchboards, control panels and machinery where consistent protection and long service life are essential.
Miniature circuit breakers such as the ABB S203P-B16 are designed to automatically disconnect electrical circuits during overload or short circuit conditions. This helps prevent cable damage, equipment failure and potential safety hazards within electrical installations.
The B curve characteristic is suitable for circuits where low inrush currents occur during normal operation. This makes the S203P-B16 a practical choice for lighting, control and general power distribution circuits where dependable protection and reduced nuisance tripping are important.
