Why Choose the ABB FS401EC200.03 RCBO?
The ABB FS401EC200.03, type code FS401E-C20/0.03, is a compact 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase final circuits against overloads, short circuits and residual earth fault currents. As part of the ABB FS401E series for the SMISSLINE TP plug-in system, it combines overcurrent and residual current protection in one modular device for residential, commercial and industrial electrical installations.
This RCBO has a 20 A rated current, C tripping characteristic and 30 mA Type A residual current sensitivity. Type A residual current protection responds to sinusoidal AC and pulsating DC earth fault currents, while the 30 mA sensitivity provides protection against indirect contact and additional protection against direct contact.
With a rated operational voltage of 240 V AC and a 6 kA rated short-circuit breaking capacity according to EN 61009-1, the FS401E-C20/0.03 delivers dependable combined circuit protection in a compact two-module format. Its SMISSLINE TP plug-in design supports efficient installation, replacement and circuit configuration within compatible ABB distribution assemblies.
