Why Choose the ABB F204 A-25/0.03 400Hz Residual Current Circuit Breaker?
The ABB F204 A-25/0.03 400Hz is a specialist four-pole residual current circuit breaker (RCCB) engineered for reliable earth fault protection in electrical systems operating at frequencies of up to 400 Hz. As part of the proven ABB F200 RCCB series, it protects both people and electrical installations by rapidly disconnecting the supply when hazardous earth leakage currents are detected.
Designed as a Type A RCCB, this device detects both alternating residual currents and pulsating DC residual currents generated by modern electrical equipment. Its 25 A rated current and 30 mA residual operating current make it ideal for high-sensitivity personnel protection in specialist high-frequency applications.
With a compact four-pole DIN rail mounted design, the ABB F204 A-25/0.03 400Hz is suitable for aerospace, naval, defence, laboratory and specialist industrial power systems where conventional 50/60 Hz protection devices are unsuitable.
Key Advantages
- Designed specifically for 400 Hz electrical systems.

Reliable Earth Fault Protection for High Frequency Power Systems
Residual current circuit breakers continuously compare the current flowing through live conductors and the neutral conductor. When an earth leakage fault occurs, the RCCB disconnects the circuit quickly, helping reduce the risk of electric shock, fire and equipment damage.
The ABB F204 A-25/0.03 400Hz has been specifically developed for electrical systems operating at 400 Hz, making it suitable for specialist installations where conventional residual current devices are not designed to operate reliably.
Typical Applications
- Aerospace ground power systems.
- Aircraft maintenance facilities.
- Naval and marine electrical systems.
- Military and defence installations.
- Laboratory and specialist industrial equipment.
- High-frequency electrical distribution systems.
