Why Choose the ABB S402M-K16 Miniature Circuit Breaker?
The ABB S402M-K16 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 16 A rated current, Type K tripping characteristic and 10 kA rated short-circuit breaking capacity.
The S402M-K16 uses thermal and electromagnetic tripping mechanisms to protect circuits against sustained overloads and short-circuit faults. Its Type K characteristic is particularly suited to circuits supplying motors and other inductive loads with elevated starting currents, helping accommodate normal switch-on conditions while maintaining dependable overcurrent protection.
Designed specifically for ABB's SMISSLINE TP distribution platform, the S402M-K16 provides efficient plug-in integration into compatible assemblies. With 2 protected poles, a 240 V AC rated voltage, IP20 protection and compact two-module construction, it provides a robust circuit-protection solution for industrial, commercial and machine-building installations.
