ABB S203P-C16 three-pole 16 A C 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-C16 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 C trip characteristic, making it suitable for circuits with moderate inrush currents such as small motors, lighting groups, transformers and general industrial loads. Its current limiting design helps reduce fault energy during short circuit conditions, supporting safer operation and helping protect connected equipment from excessive electrical stress.
With a rated current of 16 A, a three-pole configuration and a high breaking capacity of up to 25 kA, the ABB S203P-C16 is ideal for demanding three-phase circuit protection applications. It is engineered for use in distribution boards, control panels and machinery where consistent protection and long service life are essential.
Miniature circuit breakers such as the ABB S203P-C16 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 C curve characteristic is suitable for circuits where moderate inrush currents occur during normal operation. This makes the S203P-C16 a practical choice for industrial and commercial loads where nuisance tripping must be reduced while maintaining dependable protection against genuine fault conditions.
