Why Choose the ABB F202 AC-25/0.03 Residual Current Circuit Breaker?
The ABB F202 AC-25/0.03 is a high-quality 2-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 continuously monitors residual current and disconnects the supply when leakage to earth is detected, helping reduce the risk of electric shock and fire caused by insulation faults.
This RCCB features a Type AC residual current characteristic, making it suitable for detecting sinusoidal alternating residual currents typically found in standard AC electrical installations. With a rated residual operating current of 30 mA, it provides additional personal protection while maintaining dependable operation in residential, commercial and light industrial environments.
With a rated current of 25 A, a 2-pole configuration and DIN rail mounting, the ABB 2CSF202001R1250 is ideal for consumer units, distribution boards and control panels. Its compact modular design enables straightforward installation and compatibility with ABB modular accessories.

Reliable Earth Leakage Protection
Residual current circuit breakers such as the ABB F202 AC-25/0.03 compare the current flowing through the live and neutral conductors. When a difference caused by leakage to earth exceeds the rated sensitivity, the device disconnects the circuit rapidly to help protect people and equipment.
The 30 mA sensitivity provides additional protection against electric shock in accordance with many installation requirements, while the Type AC operating characteristic makes the device suitable for conventional AC loads found throughout residential and commercial installations.
Typical Applications
- Residential consumer units.
- Commercial distribution boards.
- General-purpose earth leakage protection.
- Lighting and socket outlet circuits.
- Industrial control panels.
- Single-phase electrical installations.
