Why Choose the ABB S401M-C2NP Miniature Circuit Breaker?
The ABB S401M-C2NP is a compact 1P+NP miniature circuit breaker (MCB) designed to protect both the phase and neutral conductors against overload and short-circuit currents. As part of the ABB SMISSLINE TP S400M series, it combines current-limiting circuit protection with the installation flexibility of ABB's pluggable SMISSLINE TP distribution system.
Unlike a conventional single-pole breaker with an unprotected switched neutral, the S401M-C2NP incorporates a protected neutral pole, providing overcurrent protection for both conductors while disconnecting them together. Its plug-in construction enables direct integration with compatible SMISSLINE TP socket-base assemblies, supporting efficient installation, replacement and system expansion.
With a rated current of 2 A, a Type C tripping characteristic, a rated short-circuit capacity of 10 kA Icn and a rated ultimate short-circuit breaking capacity of 25 kA Icu, the S401M-C2NP is suited to low-current circuits with moderate starting or inrush currents. It complies with EN 60898-1 and IEC/EN 60947-2 and carries ABB order code 2CCS571103R8024.
