ABB S203P-K13 three-pole 13 A miniature circuit breaker with K tripping characteristic for industrial and commercial electrical circuit protection.
The ABB S203P-K13 is a high performance three-pole miniature circuit breaker (MCB) from the trusted ABB System pro M compact S200P series. Designed for reliable overload and short circuit protection, it is ideal for industrial control panels, machinery, automation systems and commercial electrical distribution applications.
Featuring a K tripping characteristic, the S203P-K13 is particularly suitable for circuits with moderate inrush currents, such as motors, transformers and inductive loads. Its current limiting design helps reduce fault energy, while the delayed thermal and electromechanical trip mechanisms provide dependable protection against overloads and short circuits.
With a 13 A rated current, three-pole configuration and compact DIN rail mounted format, the ABB S203P-K13 delivers robust circuit protection for demanding industrial and commercial installations. It is part of ABB’s professional S200P range, offering high breaking capacity and compatibility with ABB modular accessories.
Miniature circuit breakers such as the ABB S203P-K13 protect electrical circuits by automatically disconnecting the supply when an overload or short circuit occurs. This helps protect cables, connected equipment and control systems from damage caused by excessive current.
The K curve characteristic makes this breaker well suited to inductive loads where starting currents are higher than normal operating current. Its compact size, high quality construction and accessory compatibility make it a practical choice for panel builders, OEM machine builders and electrical engineers working with industrial control systems.
