Why Choose the ABB F204 A-125/0.3 Residual Current Circuit Breaker?
The ABB F204 A-125/0.3 is a robust four-pole Residual Current Circuit Breaker (RCCB) designed to provide dependable protection against earth leakage faults in commercial, industrial and three-phase electrical installations. As part of the trusted ABB F200 series, it helps protect people, equipment and electrical systems by disconnecting the supply when residual fault currents are detected.
This RCCB features Type A residual current detection, allowing it to detect both sinusoidal AC and pulsating DC residual currents. This makes it suitable for modern electrical installations where electronic loads, power supplies, control equipment and variable speed drives may be present.
With a 125 A rated current, 300 mA residual operating current and four-pole configuration, the ABB F204 A-125/0.3 is ideal for higher-load three-phase distribution boards, industrial panels and building services applications requiring reliable earth fault protection.
Key Advantages
- Reliable ABB F200 series residual current circuit breaker.
- 125 A rated current for higher-load electrical installations.
- 300 mA residual current sensitivity for earth leakage protection.
- Type A protection for AC and pulsating DC residual currents.
- Four-pole switching suitable for three-phase systems with neutral.
- DIN rail mounted design for distribution boards and control panels.
Key Features
- ABB F200 RCCB series.
- Model F204 A-125/0.3.
- Manufacturer part number 2CSF204101R3950.
- 125 A rated current.
- 300 mA residual operating current.
- Type A residual current protection.

Reliable Earth Leakage Protection for Higher-Load Installations
Residual Current Circuit Breakers continuously monitor the current balance between live conductors and neutral. If an imbalance caused by leakage to earth is detected, the RCCB disconnects the circuit, helping reduce the risk of electric shock, insulation damage and electrical fire.
The ABB F204 A-125/0.3 is designed for dependable protection in larger three-phase installations. Its Type A detection capability makes it suitable for circuits supplying equipment with electronic components, where pulsating DC residual currents may occur.
Typical Applications
- Three-phase distribution boards.
- Commercial electrical installations.
- Industrial control panels.
- Machinery supply circuits.
- Building services and infrastructure systems.
- Manufacturing and production facilities.
