Why Choose the ABB F202 B-63/0,03 Residual Current Circuit Breaker?
The ABB F202 B-63/0,03 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 supply when hazardous residual currents are detected.
With a 63 A rated current and 30 mA residual current sensitivity, this device is suitable for higher-load circuits requiring additional protection against electric shock. Its Type B residual current detection is designed to respond to sinusoidal AC, pulsating DC and smooth DC residual currents, making it ideal for installations using power electronics, inverters and variable speed drive equipment.
The compact 2-module DIN rail format, secure screw terminal connection and robust ABB construction make the F202 B-63/0,03 a dependable solution for modern electrical systems where conventional Type AC or Type A residual current devices may not provide sufficient protection.

Advanced Type B Residual Current Protection
Residual current circuit breakers continuously monitor the balance between live and neutral conductors. If an earth leakage fault occurs, the RCCB disconnects the circuit to help reduce the risk of electric shock, electrical hazards and damage to 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-63/0,03 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.
- Photovoltaic and renewable energy systems.
- UPS, battery storage and specialist electronic load applications.
