Why Choose the ABB F204 A S-63/1 Residual Current Circuit Breaker?
The ABB F204 A S-63/1 is a premium four-pole selective residual current circuit breaker (RCCB) designed to provide dependable earth fault protection in commercial, industrial and infrastructure electrical installations. As part of the trusted ABB F200 RCCB series, it protects people, equipment and installations by detecting residual current faults and disconnecting the circuit when leakage current exceeds the rated threshold.
This Type A selective RCCB detects alternating residual currents and pulsating DC residual currents generated by modern electrical equipment. Its 63 A rated current and 1000 mA residual operating current make it suitable for upstream protection in three-phase distribution systems where selective coordination with downstream residual current devices is required.
With its four-pole DIN rail mounted design, screw terminal connections and compact modular housing, the F204 A S-63/1 is ideal for professional switchboards, distribution boards and control panels requiring reliable residual current protection with delayed selective tripping behaviour.

Selective Earth Fault Protection for Reliable Distribution
Residual current circuit breakers continuously monitor the balance between live conductors and the neutral conductor. If earth leakage is detected, the RCCB disconnects the circuit to help reduce the risk of electric shock, electrical fires and damage to connected equipment.
The selective operating characteristic of the ABB F204 A S-63/1 provides delayed tripping compared with downstream RCCBs, improving discrimination and helping maintain continuity of service by isolating only the affected section of an installation.
Typical Applications
- Commercial electrical distribution boards.
- Industrial switchboards and control panels.
- Three-phase power distribution systems.
- Building services and infrastructure installations.
- Machinery and automation systems.
- Upstream selective residual current protection.
