Why Choose the ABB F204 A-25/0.03 Residual Current Circuit Breaker?
The ABB F204 A-25/0.03 is a high-quality 4 pole residual current circuit breaker (RCCB) designed to provide dependable protection against earth leakage faults in commercial, industrial and infrastructure electrical installations. As part of the trusted ABB F200 Series, it helps protect people and electrical systems by disconnecting the supply when residual fault current is detected.
Featuring a 25 A rated current and a 30 mA rated residual operating current, this RCCB is suitable for three-phase distribution systems where personnel protection and reliable earth fault detection are required. The Type A tripping characteristic detects alternating sinusoidal residual currents and pulsating DC residual currents, making it suitable for many modern electrical installations.
The F204 A-25/0.03 is designed for DIN rail mounting inside distribution boards, switchgear assemblies and control panels. Its compact modular design, screw terminal connections and ABB engineering quality make it a dependable choice for professional electrical installations.
