ABB F204 A-25/0.03 400Hz four-pole Type A residual current circuit breaker rated at 25 A with 30 mA sensitivity for specialist 400 Hz electrical installations.
£414.41
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.
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.

This RCCB provides earth fault protection for specialist electrical installations operating at 400 Hz, including aerospace, marine and other high-frequency power systems.
The 30 mA residual operating current provides additional protection against electric shock by disconnecting the circuit when earth leakage exceeds the rated threshold.
Type A RCCBs detect both alternating residual currents and pulsating DC residual currents produced by many modern electrical loads.
This version is engineered specifically for high-frequency electrical systems operating at 400 Hz, ensuring dependable performance where standard 50/60 Hz devices are unsuitable.
The RCCB mounts directly onto a standard DIN rail within switchboards, distribution boards and electrical control panels.
ABB F200 residual current circuit breakers are trusted worldwide for delivering dependable earth fault protection across commercial, industrial and specialist high-frequency electrical installations.
