Why Choose the ABB F202 B-25/0,03 Residual Current Circuit Breaker?
The ABB F202 B-25/0,03 is a premium residual current circuit breaker (RCCB) engineered to provide reliable protection against earth fault currents in demanding residential, commercial and industrial electrical installations. As part of the advanced ABB F200 Type B series, this 2-pole RCCB disconnects the electrical supply when hazardous residual currents are detected, helping to safeguard people, equipment and electrical systems.
With a 25 A rated current and 30 mA residual current sensitivity, the device provides additional protection against electric shock. Its Type B residual current detection responds to sinusoidal AC, pulsating DC and smooth DC fault currents, making it suitable for applications involving power electronics, variable speed drives, EV charging infrastructure and renewable energy systems.
Featuring a compact 2-module DIN rail design, secure screw terminals and ABB's proven engineering quality, the F202 B-25/0,03 is an ideal solution for installations where conventional Type AC or Type A RCCBs are not sufficient.

Advanced Type B Residual Current Protection
Residual current circuit breakers continuously monitor the balance between live and neutral conductors. When a leakage current develops, the RCCB disconnects the circuit within milliseconds to help minimise the risk of electric shock and reduce damage to connected electrical equipment.
Unlike conventional Type AC or Type A devices, the ABB F202 B-25/0,03 is designed to detect smooth DC residual currents as well as AC and pulsating DC leakage currents. This makes it particularly suitable for modern installations using inverters, frequency converters, EV charging systems and renewable energy technologies.
Typical Applications
- Electric vehicle charging installations.
- Variable speed drive and inverter-fed systems.
- Photovoltaic and renewable energy systems.
- UPS and battery storage installations.
- Industrial automation and control panels.
- Commercial electrical distribution systems requiring Type B protection.
