ABB F204 A-40/0.5 four pole Type A residual current circuit breaker with 40 A rated current and 500 mA residual operating current for three-phase electrical protection.
£245.22
The ABB F204 A-40/0.5 is a dependable four-pole Residual Current Circuit Breaker (RCCB) designed to provide 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, control equipment, power supplies and variable speed drives may be present.
With a 40 A rated current, 500 mA residual operating current and four-pole configuration, the ABB F204 A-40/0.5 is ideal for three-phase distribution boards, industrial control panels and building services applications requiring reliable earth fault protection.
Residual Current Circuit Breakers continuously monitor the balance of current flowing through live conductors and neutral. If an imbalance caused by leakage to earth is detected, the RCCB disconnects the circuit, helping reduce the risk of electric shock, insulation damage and electrical fire.
The ABB F204 A-40/0.5 is designed for dependable protection in modern three-phase installations. Its Type A detection capability makes it suitable for circuits supplying equipment with electronic components, where pulsating DC residual currents may occur.
