Why Choose the ABB F204 A-40/0.03 400Hz Residual Current Circuit Breaker?
The ABB F204 A-40/0.03 400Hz is a specialist four-pole residual current circuit breaker (RCCB) designed to provide dependable earth fault protection in electrical systems operating at frequencies of up to 400 Hz. As part of the proven ABB F200 RCCB series, it safeguards both personnel and electrical installations by disconnecting the supply when dangerous earth leakage currents are detected.
This Type A RCCB detects alternating residual currents and pulsating DC residual currents generated by modern electrical equipment. Its 40 A rated current and 30 mA residual operating current make it ideal for high-sensitivity protection in specialist high-frequency electrical systems including aerospace, marine and defence applications.
Featuring a compact four-pole DIN rail mounted design, the ABB F204 A-40/0.03 400Hz is engineered for reliable operation where conventional 50/60 Hz RCCBs are unsuitable, delivering trusted ABB protection for demanding industrial environments.
Key Advantages
Designed specifically for 400 Hz electrical systems.
40 A rated current for specialist low voltage applications.
30 mA residual current sensitivity for personal protection against electric shock.
Type A protection detects AC and pulsating DC residual currents.
Compact 4-pole DIN rail mounted RCCB.
Trusted ABB quality for demanding industrial and specialist installations.
Key Features
ABB F200 residual current circuit breaker series.
Four-pole (4P) RCCB configuration.
40 A rated operational current.
30 mA rated residual operating current.
Type A residual current protection.
Rated frequency: 50 to 400 Hz.
Suitable for 230/400 V AC installations.

Reliable Earth Fault Protection for High Frequency Power Systems
Residual current circuit breakers continuously compare the current flowing through the live conductors and neutral conductor. When an earth leakage fault occurs, the RCCB disconnects the circuit rapidly, helping reduce the risk of electric shock, electrical fires and equipment damage.
The ABB F204 A-40/0.03 400Hz has been developed specifically for installations operating at frequencies up to 400 Hz, ensuring dependable protection in specialist applications where standard RCCBs are not suitable.
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.

Frequently Asked Questions
What is the ABB F204 A-40/0.03 400Hz used for?
This RCCB provides earth fault protection for specialist electrical installations operating at frequencies up to 400 Hz, including aerospace, marine and other high-frequency power systems.
What does the 30 mA rating represent?
The 30 mA residual operating current provides additional protection against electric shock by disconnecting the circuit when earth leakage exceeds the rated threshold.
What does Type A protection mean?
Type A RCCBs detect both alternating residual currents and pulsating DC residual currents generated by many modern electronic loads.
Why is this RCCB suitable for 400 Hz systems?
This model is engineered for operation at frequencies up to 400 Hz, making it suitable for specialist installations where conventional 50/60 Hz devices are unsuitable.
How is the ABB F204 A-40/0.03 400Hz installed?
The RCCB mounts directly onto a standard DIN rail within distribution boards, switchboards and electrical control panels.
