Why Choose the ABB F204 A-63/0.3 16.7Hz Residual Current Circuit Breaker?
The ABB F204 A-63/0.3 16.7Hz is a specialist four-pole residual current circuit breaker (RCCB) designed to provide reliable earth fault protection in low voltage electrical installations operating at 16.7 Hz. As part of the proven ABB F200 RCCB series, it protects people and electrical installations by monitoring residual current and disconnecting the supply when an earth leakage fault is detected.
This Type A RCCB detects both alternating residual currents and pulsating DC residual currents. With a 63 A rated current and 300 mA residual operating current, it is ideal for installation-level earth fault protection in specialist low frequency power systems, including railway infrastructure operating at 16 2/3 Hz.
Its four-pole design, DIN rail mounting and compact modular construction make the F204 A-63/0.3 16.7Hz suitable for professional switchboards, control panels and distribution systems where dependable protection and long service life are essential.

Reliable Earth Fault Protection for Specialist Power Systems
Residual current circuit breakers continuously monitor the balance between live conductors and neutral. When an earth leakage fault is detected, the RCCB disconnects the circuit rapidly, helping reduce the risk of electric shock, electrical fires and equipment damage.
The ABB F204 A-63/0.3 16.7Hz has been developed specifically for low frequency electrical networks operating at 16 2/3 Hz, making it particularly suitable for railway infrastructure and other specialist applications where conventional 50/60 Hz devices are not appropriate.
Typical Applications
- Railway electrical distribution systems.
- Traction power infrastructure.
- Industrial switchboards.
- Commercial distribution boards.
- Control panels and electrical assemblies.
- Special frequency low voltage power installations.
