Why Choose the ABB F204 A-40/0.3 Residual Current Circuit Breaker?
The ABB F204 A-40/0.3 is a high performance four-pole Residual Current Circuit Breaker (RCCB) designed to provide dependable protection against earth leakage faults in commercial, industrial and large residential electrical installations. As part of the trusted ABB F200 series, it offers reliable protection for people and electrical equipment by disconnecting the supply when dangerous residual currents are detected.
Designed with Type A residual current detection, the F204 A-40/0.3 protects against both sinusoidal alternating and pulsating DC earth fault currents, making it suitable for modern electrical systems containing electronic equipment and power supplies. Its robust DIN rail mounted construction and high mechanical endurance make it ideal for demanding applications requiring long-term reliability.
With a 40 A rated current, 300 mA residual operating current and a four-pole configuration, this RCCB is commonly installed as part of three-phase distribution systems where dependable earth fault protection is essential for electrical safety and system continuity.
