Why Choose the ABB S401M-K13NP Miniature Circuit Breaker?
The ABB S401M-K13NP is a pluggable 1P+NP miniature circuit breaker (MCB) with protected neutral designed to protect electrical circuits against overload and short-circuit currents. Part of the ABB S400M SMISSLINE TP plug-in series, it combines dependable circuit protection with a modular format designed for efficient professional low-voltage distribution.
This circuit breaker has a rated current of 13 A, a Type K tripping characteristic and a rated short-circuit breaking capacity of 10 kA. Its rated operational voltage is 240 V AC, while the S400M-K protected-neutral design provides an ultimate short-circuit breaking capacity of 25 kA at 240 V AC for this 13 A model.
The S401M-K13NP incorporates a protected neutral, with the neutral protected at 100% of the nominal value of the pole conductor. Its 2-module SMISSLINE TP format and plug-in mounting simplify integration into compatible ABB distribution systems while supporting efficient installation, maintenance and future circuit modifications.
