ABB S401P-B63NP is a 63 A Type B 1P+NP miniature circuit breaker with protected neutral and 20 kA ultimate short-circuit breaking capacity for the SMISSLINE TP plug-in system.
£109.46
The ABB S401P-B63NP is a high-performance miniature circuit breaker (MCB) with protected neutral designed for reliable overload and short-circuit protection in low-voltage electrical distribution systems. As part of the ABB S400P range for the SMISSLINE TP plug-in system, it combines dependable circuit protection with a flexible plug-in architecture for commercial, industrial and critical-power installations.
This MCB features a Type B tripping characteristic and a rated current of 63 A. The S400P design provides thermal protection against sustained overloads together with electromagnetic protection against short-circuit faults, helping protect cables, conductors and connected electrical circuits.
With an ultimate short-circuit breaking capacity of 20 kA and a 1P+NP configuration, the S401P-B63NP provides high-current circuit protection in a compact two-module format. Its SMISSLINE TP plug-in connection enables straightforward installation and replacement within compatible electrical distribution assemblies.
Miniature circuit breakers such as the ABB S401P-B63NP protect electrical cables and circuits against overload and short-circuit currents. Thermal tripping responds to sustained overload conditions, while electromagnetic tripping provides rapid disconnection when a short-circuit fault occurs.
The ABB SMISSLINE TP system uses a plug-in distribution architecture that allows compatible protective devices to connect directly to the socket system. This approach supports flexible electrical distribution designs while helping simplify installation, servicing and future modifications within commercial and industrial distribution assemblies.
