Why Choose the ABB S402M-D32 Miniature Circuit Breaker?
The ABB S402M-D32 is a high-performance 2-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in electrical distribution systems. Part of the ABB S400M range for the SMISSLINE TP plug-in system, it combines a 32 A rated current, Type D tripping characteristic and 10 kA rated short-circuit breaking capacity.
The S402M-D32 incorporates two protective tripping mechanisms: a delayed thermal release for overload protection and an electromagnetic release for rapid short-circuit protection. Its Type D characteristic is particularly suitable for circuits supplying equipment with relatively high starting or inrush currents, helping prevent unnecessary tripping during normal equipment start-up.
Designed specifically for ABB's SMISSLINE plug-in distribution platform, the S402M-D32 provides efficient integration into compatible assemblies. With two protected poles, a 400 V AC rated voltage, compact two-module construction and IP20 protection, it is a practical choice for industrial, commercial and machine-building electrical distribution.
