The ABB F204A-40/0.3 is a robust, 4-pole Type A Residual Current Circuit Breaker (RCCB) engineered to provide comprehensive electrical safety in complex three-phase systems. This high-performance RCCB delivers crucial protection against dangerous earth fault currents, dramatically minimising the risk of electric shock and preventing electrical fires. Rated at 40A with a 300mA trip sensitivity, it is perfectly suited for installation in commercial and light industrial applications where high levels of safety and strict regulatory compliance (IEC/EN 61008) are paramount.
Implementing this RCCB is vital for safeguarding personnel and expensive electrical equipment from dangerous earth-leakage currents. It provides dedicated earth-fault protection, ensuring rapid power disconnection when an imbalance is detected. The advanced Type A tripping characteristic is specifically designed to reliably detect both alternating current (AC) and pulsating direct current (DC) residual currents, providing enhanced safety for circuits with modern electronic loads.
