ABB F204 A-100/0.03 L four pole Type A residual current circuit breaker with 100 A rated current, 30 mA residual operating current and left-side neutral arrangement for commercial and industrial electrical protection.
£457.36
The ABB F204 A-100/0.03 L is a high quality four-pole Residual Current Circuit Breaker (RCCB) designed to provide reliable 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-100/0.03 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 100 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.
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-100/0.03 L combines sensitive 30 mA residual current protection with ABB's proven engineering, making it suitable for higher-load installations where dependable safety, long service life and compatibility with left-neutral panel arrangements are important.
