Why Choose the ABB S401MC2 Miniature Circuit Breaker?
The ABB S401MC2, type designation S401M-C2, is a single-pole miniature circuit breaker (MCB) designed for the ABB SMISSLINE TP plug-in system. Rated at 2 A with a Type C tripping characteristic, it provides overload and short-circuit protection for low-current electrical circuits in commercial, industrial and critical-power applications.
The S401M-C2 has a rated short-circuit capacity of 10 kA according to EN 60898-1 and an ultimate short-circuit breaking capacity of 25 kA according to IEC/EN 60947-2. Its current-limiting design combines a delayed thermal tripping mechanism for overload protection with an electromagnetic tripping mechanism for short-circuit protection.
Purpose-designed for the SMISSLINE TP system, the S401M-C2 uses ABB's plug-in architecture for efficient installation within compatible distribution assemblies. The breaker occupies 1 module, weighs approximately 110 g and is supplied by ABB in packaging units of 10 pieces.
Key Advantages

Reliable Current-Limiting Circuit Protection
The ABB S401M-C2 uses two complementary tripping mechanisms to protect connected circuits. A delayed thermal mechanism responds to sustained overload conditions, while an electromagnetic mechanism provides rapid operation during short circuits. This current-limiting construction helps reduce the electrical stress associated with high fault currents.
With a 2 A Type C rating, 10 kA Icn according to EN 60898-1 and 25 kA Icu according to IEC/EN 60947-2, the S401M-C2 provides robust protection for low-current circuits. Its SMISSLINE TP plug-in format supports efficient installation and replacement within compatible modular distribution systems.
