£218.73
The ABB F204 A-25/0.5 is a dependable four-pole Residual Current Circuit Breaker (RCCB) designed to protect people and electrical installations against earth leakage faults. As part of the trusted ABB F200 series, it provides reliable residual current protection for commercial, industrial and three-phase electrical systems where dependable safety is essential.
Featuring Type A residual current detection, the F204 A-25/0.5 detects both sinusoidal AC and pulsating DC residual currents, making it suitable for modern installations containing electronic equipment, power supplies, automation systems and variable speed drives.
With a 25 A rated current, 500 mA residual operating current and a four-pole configuration, this RCCB is ideal for three-phase distribution boards, industrial machinery and commercial electrical installations requiring reliable earth fault protection.
Residual Current Circuit Breakers continuously monitor the balance of current flowing through live conductors and neutral. If an earth leakage fault occurs, the RCCB disconnects the circuit rapidly, helping reduce the risk of electric shock, equipment damage and electrical fire.
The ABB F204 A-25/0.5 combines dependable residual current protection with proven ABB engineering, making it suitable for modern electrical installations where long-term reliability and compliance are essential.
