Why Choose the ABB 2CSF204101R3900 F204 A-100/0.3 Residual Current Circuit Breaker?
The ABB 2CSF204101R3900, also known as the ABB F204 A-100/0.3, is a high quality four-pole Residual Current Circuit Breaker (RCCB) designed to provide reliable 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 installations where electronic loads, power supplies, control systems and variable speed drives may be present.
With a 100 A rated current, 300 mA residual operating current and four-pole configuration, the ABB 2CSF204101R3900 is ideal for higher-load three-phase distribution boards, industrial control panels and building services applications requiring dependable earth fault protection.

Reliable Earth Leakage Protection for Higher-Load Installations
Residual Current Circuit Breakers continuously monitor the balance of current flowing through the 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-100/0.3 is designed for dependable protection in larger three-phase installations. Its Type A detection capability makes it well suited to 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.
