Why Choose the ABB F204 A-125/0.03 L Residual Current Circuit Breaker?
The ABB F204 A-125/0.03 L is a high quality 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 proven ABB F200 series, it helps protect people, equipment and electrical systems by disconnecting the supply when residual fault currents are detected.
Featuring Type A residual current detection, the F204 A-125/0.03 L detects both sinusoidal AC and pulsating DC residual currents, making it suitable for modern electrical systems containing electronic equipment, power supplies, automation controls and variable speed drives.
With a 125 A rated current, 30 mA residual operating current, four-pole configuration and left-side neutral arrangement, this RCCB is ideal for higher-load three-phase distribution boards, industrial control panels and installations requiring sensitive residual current protection.
