Why Choose the ABB FS403MK-C6/0.3 RCBO?
The ABB FS403MK-C6/0.3 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 FS403M-K Type F RCBO series, this device provides enhanced residual current detection for circuits containing modern electronic equipment. Its Type F residual current characteristic supports detection of mixed-frequency residual currents, while the short-time delayed design improves resistance to unwanted tripping and helps maintain continuity of service.
The FS403MK-C6/0.3 features a 6 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 3P+N configuration and SMISSLINE TP plug-in format make it suitable for efficient installation in compatible ABB distribution systems.
