Why Choose the ABB FS403MK-C10/0.3 RCBO?
The ABB FS403MK-C10/0.3 is a high-performance 3P+N residual current circuit breaker with overcurrent protection (RCBO) designed for the ABB SMISSLINE TP plug-in distribution system. Combining overload, short-circuit and residual current protection in a single compact device, it provides dependable circuit protection for commercial and industrial electrical distribution applications.
As part of the ABB FS403MK Type F RCBO range, this device combines short-time delayed operation with Type F residual current protection. This enables detection of mixed-frequency residual currents up to 1 kHz while providing increased resistance to unwanted tripping, helping maintain continuity of service in installations containing modern electronic equipment.
The FS403MK-C10/0.3 features a 10 A rated current, C tripping characteristic, 300 mA rated residual operating current and 10 kA rated breaking capacity according to IEC/EN 61009-1. Its four-pole 3P+N configuration and SMISSLINE TP plug-in format enable efficient integration into compatible ABB electrical distribution systems.
