Why Choose the ABB 2CSF204401R1250 Residual Current Circuit Breaker?
The ABB 2CSF204401R1250, also known as F204 A-25/0.03 AP-R, is a reliable 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 dependable residual current protection for commercial, industrial and infrastructure applications.
This RCCB features Type A residual current protection, making it suitable for detecting alternating residual currents and pulsating DC residual currents. Its AP-R high immunity design helps reduce unwanted nuisance tripping caused by transient disturbances, making it ideal for installations where safety and continuity of service are both important.
With a 25 A rated current, 30 mA residual operating current and 4 pole configuration, the ABB 2CSF204401R1250 is well suited to three phase distribution boards, industrial panels, machinery circuits and commercial electrical installations requiring high quality residual current protection.

High Immunity Earth Leakage Protection
Residual current circuit breakers monitor the current balance between conductors and disconnect the supply when a residual earth leakage fault is detected. This helps reduce the risk of electric shock and supports safer operation of electrical installations.
The ABB 2CSF204401R1250 combines Type A detection with AP-R high immunity performance, making it suitable for environments where electronic equipment, transient disturbances or network fluctuations could otherwise cause unwanted tripping.
Typical Applications
- Commercial electrical distribution boards.
- Industrial control panels.
- Three phase power distribution systems.
- Machinery and automation circuits.
- Infrastructure and public building installations.
- Installations requiring Type A high immunity residual current protection.
