Why Choose the ABB F204ACS-40/0.3 Residual Current Circuit Breaker?
The ABB F204ACS-40/0.3, also known as F204 AC-40/0.3, is a professional 4 pole residual current circuit breaker (RCCB) designed to protect people and electrical installations against earth fault currents. As part of the trusted ABB F200 series, it provides reliable 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 300 mA residual operating current is commonly used for fault protection and fire protection applications where disconnection is required in response to earth leakage.
With a 40 A rated current, 300 mA residual current sensitivity and 4 pole configuration, the ABB F204ACS-40/0.3 is ideal for three phase distribution boards, commercial installations, industrial panels and general electrical protection systems.

Reliable 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 people, equipment and electrical installations against faults caused by insulation failure or leakage to earth.
The ABB F204ACS-40/0.3 provides Type AC residual current protection for installations where alternating sinusoidal residual currents may occur. Its 300 mA sensitivity makes it suitable for upstream protection, fire protection and general earth fault protection across commercial and industrial electrical systems.
Typical Applications
- Commercial electrical distribution boards.
- Industrial control panels.
- Three phase power distribution systems.
- Building services and infrastructure installations.
- General fault protection circuits.
- Installations requiring 300 mA Type AC residual current protection.
