Why Choose the ABB F204 A-125/0.3 Residual Current Circuit Breaker?
The ABB F204 A-125/0.3 is a robust four-pole Residual Current Circuit Breaker (RCCB) designed to provide dependable protection against earth leakage faults in commercial, industrial and three-phase electrical installations. As part of the trusted ABB F200 series, it helps protect people, equipment and electrical systems by disconnecting the supply when residual fault currents are detected.
This RCCB features Type A residual current detection, allowing it to detect both sinusoidal AC and pulsating DC residual currents. This makes it suitable for modern electrical installations where electronic loads, power supplies, control equipment and variable speed drives may be present.
With a 125 A rated current, 300 mA residual operating current and four-pole configuration, the ABB F204 A-125/0.3 is ideal for higher-load three-phase distribution boards, industrial panels and building services applications requiring reliable earth fault protection.
