Why Choose the ABB FS403MKC160.3 RCBO?
The ABB FS403MKC160.3, type designation FS403MK-C16/0.3, is a 3P+N residual current circuit breaker with overcurrent protection (RCBO) designed for the ABB SMISSLINE TP plug-in system. It combines overload, short-circuit and residual-current protection in a single four-pole protective device for industrial and commercial electrical distribution.
This FS403MK series RCBO has a 16 A rated current, C tripping characteristic and 300 mA rated residual operating current. Its Type F residual-current characteristic is suitable for circuits incorporating modern electronic equipment, while its high-immunity, short-time delayed design helps reduce unwanted tripping caused by transient residual currents.
With a 10 kA rated short-circuit breaking capacity according to EN 61009-1, the FS403MK-C16/0.3 provides dependable protection for three-phase circuits. Its plug-in construction enables direct connection to the SMISSLINE TP socket system, supporting efficient installation, replacement and maintenance in compatible electrical distribution assemblies.

Reliable Circuit Protection for SMISSLINE Distribution Systems
RCBOs combine the protective functions of a miniature circuit breaker and a residual-current protective device. The ABB FS403MK-C16/0.3 therefore protects connected circuits against overload and short-circuit currents while also detecting residual currents, providing coordinated circuit and residual-current protection within one compact device.
The SMISSLINE TP plug-in architecture allows compatible protective devices to connect directly to the socket system, supporting efficient installation and servicing. The Type F characteristic is suitable for circuits containing electronic equipment capable of producing complex residual-current waveforms, while the 300 mA sensitivity and high-immunity design make this model suitable for installations requiring dependable residual-current and preventive fire protection.
Typical Applications
- ABB SMISSLINE TP electrical distribution boards.
- Industrial control and power distribution panels.
- Commercial building electrical distribution.
- Three-phase circuits requiring combined overcurrent and residual-current protection.
- Circuits incorporating electronic equipment suitable for Type F protection.
- Electrical installations requiring 300 mA residual-current protection.
