Why Choose the ABB F204 AC-40/0.03APR Residual Current Circuit Breaker?
The ABB F204 AC-40/0.03APR is a high performance 4 pole residual current circuit breaker (RCCB) designed to protect people and electrical installations against earth fault currents. As part of the trusted ABB F200 series, this device provides dependable residual current protection for commercial, industrial and infrastructure electrical installations.
Featuring APR (High Immunity) technology, this RCCB offers increased resistance to unwanted nuisance tripping caused by transient voltages and electrical disturbances while maintaining fast protection against dangerous earth leakage currents. This improves system availability without compromising electrical safety.
With a 40 A rated current, 30 mA residual operating current and support for 230/400 V AC three phase systems with neutral, the ABB F204 AC-40/0.03APR is ideal for protecting distribution boards, machinery, commercial buildings and industrial electrical installations where continuity of service is essential.

Reliable Earth Leakage Protection
Residual current circuit breakers continuously monitor the balance between live conductors and disconnect the electrical supply immediately when earth leakage is detected. This helps minimise the risk of electric shock while protecting electrical installations from faults caused by insulation failure.
The ABB F200 APR range has been developed for installations where electrical disturbances could otherwise lead to unnecessary interruptions. High immunity technology provides improved operational continuity while maintaining compliance with international safety standards.
Typical Applications
- Commercial electrical distribution boards.
- Industrial control panels.
- Manufacturing facilities.
- Infrastructure and public buildings.
- Machine installations requiring residual current protection.
- Three phase electrical distribution systems.
