ABB S401M-K63 is a 63 A single-pole Type K miniature circuit breaker for the SMISSLINE plug-in system, providing overload and short-circuit protection with a 10 kA rated breaking capacity.
£45.36
The ABB S401M-K63 is a high-performance single-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overload and short-circuit conditions. As part of the ABB SMISSLINE plug-in system, it combines dependable circuit protection with a compact modular format for professional industrial and commercial power distribution.
Featuring a 63 A rated current and Type K tripping characteristic, the S401M-K63 is particularly suited to circuits supplying motors, transformers and other inductive equipment with elevated starting currents. Its plug-in construction simplifies installation, replacement and expansion within compatible ABB SMISSLINE distribution assemblies.
The S401M-K63 provides a 10 kA rated short-circuit breaking capacity according to EN 60898-1 and an ultimate short-circuit breaking capacity of 15 kA according to IEC/EN 60947-2. With a rated voltage of 240 V AC, compact one-module width and IP20 protection, it is engineered for reliable circuit protection in demanding electrical installations.
Miniature circuit breakers such as the ABB S401M-K63 automatically interrupt the electrical supply when excessive current is caused by an overload or short circuit. This helps protect cables, connected equipment and electrical installations against potentially damaging fault currents.
The ABB SMISSLINE system uses a modular plug-in distribution architecture designed to simplify installation and replacement of protective devices. Combined with its Type K characteristic, the S401M-K63 provides effective protection for circuits supplying motors, transformers and other equipment that can experience elevated starting currents during normal operation.
