ABB S403P-B8NP 3P+NP 8 A Type B miniature circuit breaker with 40 kA Icu breaking capacity, designed for the SMISSLINE TP plug-in distribution system.
£129.02
The ABB S403P-B8NP is a high-performance three-pole plus protected neutral miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in industrial and commercial electrical distribution systems. As part of the ABB S400P range for the SMISSLINE TP plug-in system, it combines high fault-current interruption capability with ABB's practical plug-in distribution architecture.
Featuring a Type B tripping characteristic and a rated current of 8 A, the S403P-B8NP is designed for compatible three-phase plus neutral circuits requiring dependable overcurrent protection. Its 3P+NP configuration provides three phase poles together with a protected neutral pole, offering coordinated circuit protection within a compact four-module device.
With a rated ultimate short-circuit breaking capacity of 40 kA according to IEC/EN 60947-2, the S403P-B8NP is suitable for demanding installations where high prospective fault currents may occur. Its SMISSLINE TP plug-in format enables efficient integration with compatible socket-base assemblies, supporting straightforward installation, replacement and maintenance.
Miniature circuit breakers such as the ABB S403P-B8NP automatically interrupt an electrical circuit when excessive current caused by an overload or short circuit occurs. This helps protect cables, conductors, connected equipment and distribution infrastructure against thermal and electrical damage associated with overcurrent conditions.
The ABB SMISSLINE TP system uses a plug-in architecture that enables compatible protective devices to connect efficiently to its socket-base system. Combined with the S403P-B8NP's 3P+NP configuration and high short-circuit breaking capacity, this provides an effective circuit-protection solution for professional industrial and commercial electrical distribution.
