Why Choose the ABB F204ACS-63/1 Residual Current Circuit Breaker?
The ABB F204ACS-63/1, also known as F204 AC S-63/1, is a professional 4 pole residual current circuit breaker (RCCB) designed to protect electrical installations against earth fault currents. As part of the trusted ABB F200 selective RCCB series, it provides reliable upstream residual current protection for commercial, industrial and infrastructure electrical systems.
This RCCB provides Type AC residual current protection, making it suitable for detecting alternating sinusoidal residual currents. Its selective S-type operating characteristic introduces a time delay, helping improve discrimination with downstream residual current devices and reducing unnecessary interruption of the wider electrical installation.
With a 63 A rated current, 1 A residual operating current and 4 pole configuration, the ABB F204ACS-63/1 is ideal for upstream protection in three phase distribution boards, industrial switchboards and commercial installations where coordinated earth leakage protection is required.
Key Advantages
- Professional 4 pole RCCB for three phase electrical installations.
- 63 A rated current for commercial and industrial distribution circuits.
- 1 A residual current sensitivity for upstream fault protection.

Selective Type AC Earth Leakage Protection
Residual current circuit breakers monitor the current balance between conductors and disconnect the supply when residual earth leakage current is detected. This helps protect electrical systems against insulation faults and supports safer operation of commercial and industrial installations.
The ABB F204ACS-63/1 provides selective Type AC residual current protection, making it suitable for upstream installation where coordination with downstream devices is important. Its delayed tripping characteristic helps maintain continuity of service by allowing downstream protection to operate first where appropriate.
Typical Applications
- Main distribution boards.
- Commercial electrical installations.
- Industrial switchboards and control panels.
- Three phase power distribution systems.
- Infrastructure electrical systems.
- Installations requiring selective Type AC residual current protection.
