ABB F204 A-63/0.3 16.7Hz four-pole Type A residual current circuit breaker rated at 63 A with 300 mA sensitivity for specialist 16.7 Hz electrical installations.
£434.71
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.
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.

This RCCB provides earth fault protection for specialist electrical systems operating at 16.7 Hz, including railway infrastructure and other low frequency installations.
The 300 mA residual operating current determines the earth leakage level at which the RCCB disconnects the electrical supply.
Type A RCCBs detect both alternating residual currents and pulsating DC residual currents produced by many modern electrical loads.
This version is specifically engineered for electrical systems operating at 16 2/3 Hz, commonly found within railway power networks.
The RCCB mounts directly onto a standard DIN rail within electrical distribution boards and control panels.
ABB F200 residual current circuit breakers are trusted by electrical contractors, panel builders and infrastructure engineers worldwide for dependable earth fault protection and long-term reliability in demanding installations.
