Why Choose the ABB F202 B-25/0.3 Residual Current Circuit Breaker?
The ABB 2CSF202568R3250, also known as the ABB F202 B-25/0.3, is a high-performance residual current circuit breaker (RCCB) designed to provide advanced protection against earth fault currents in residential, commercial and industrial electrical installations. As part of the specialist ABB F200 Type B series, this 2-pole RCCB helps protect people, equipment and electrical systems by disconnecting the circuit when hazardous residual currents are detected.
With a 25 A rated current and 300 mA residual current sensitivity, this RCCB is suitable for installations requiring fault current protection and enhanced fire protection. Its Type B residual current detection is designed to respond to sinusoidal AC, pulsating DC and smooth DC residual currents, making it suitable for modern electrical systems using inverters, drives, EV charging equipment and other power electronic loads.
The compact 2-module DIN rail format, secure screw terminal connection and proven ABB construction make the F202 B-25/0.3 a dependable solution for electrical distribution boards and control panels where advanced residual current protection is required.

Advanced Type B Residual Current Protection
Residual current circuit breakers continuously monitor the current balance between live and neutral conductors. If an earth leakage fault occurs, the RCCB disconnects the circuit to help reduce the risk of electrical hazards and protect connected equipment.
Type B RCCBs are designed for installations where residual currents may include smooth DC components as well as AC and pulsating DC leakage currents. This makes the ABB F202 B-25/0.3 particularly suitable for circuits involving frequency converters, inverters, EV chargers, photovoltaic systems, UPS units and other modern power electronic equipment.
Typical Applications
- Commercial distribution boards.
- Industrial control panels and sub-distribution systems.
- Variable speed drive and inverter-fed circuits.
- Electric vehicle charging installations.
