Why Choose the ABB F204 A-63/0.03 16.7Hz Residual Current Circuit Breaker?
The ABB F204 A-63/0.03 16.7Hz is a specialist four-pole residual current circuit breaker (RCCB) designed to provide dependable earth fault protection in low voltage electrical installations operating at 16.7 Hz. As part of the trusted ABB F200 RCCB series, it helps protect people and installations by detecting residual current faults and disconnecting the circuit when leakage current exceeds the rated threshold.
This Type A RCCB is suitable for applications where protection against alternating residual currents and pulsating DC residual currents is required. Its 63 A rated current and 30 mA residual current sensitivity make it suitable for installations requiring high-sensitivity residual current protection in specialist power systems.
With a four-pole configuration, 400 V AC rated voltage and DIN rail mounting design, the F204 A-63/0.03 16.7Hz is suited to professional electrical panels, distribution boards and railway-related electrical systems where 16.7 Hz operation is required.

Reliable Earth Fault Protection for 16.7 Hz Systems
Residual current circuit breakers monitor the difference between live and neutral conductors. If leakage current to earth is detected, the RCCB disconnects the circuit to help reduce the risk of electric shock, electrical fire and equipment damage.
The ABB F204 A-63/0.03 16.7Hz is designed for specialist applications where standard 50/60 Hz RCCBs are not appropriate. Its 16.7 Hz operating capability makes it suitable for railway-related and special frequency power systems requiring reliable residual current protection.
Typical Applications
- Railway electrical installations using 16.7 Hz supply systems.
- Special frequency low voltage distribution systems.
- Commercial and industrial distribution boards.
- Electrical control panels and switchgear assemblies.
- Machinery and infrastructure power systems.
- High-sensitivity earth leakage protection applications.
