Why Choose the ABB F202 B-40/0,03 Residual Current Circuit Breaker?
The ABB F202 B-40/0,03 is a high-quality residual current circuit breaker (RCCB) designed to provide dependable protection against earth fault currents in residential, commercial and industrial electrical installations. As part of the proven ABB F200 series, this 2-pole RCCB helps protect people and electrical systems by disconnecting the circuit when residual current leakage is detected.
With a 40 A rated current and 30 mA residual current sensitivity, this device is suitable for 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 suitable for specialist applications where electronic equipment, drives or power conversion devices may be present.
The compact 2-module DIN rail format, robust screw terminals and ABB’s established modular design make the F202 B-40/0,03 ideal for distribution boards, control panels and electrical installations requiring enhanced residual current protection.

Type B Residual Current Protection for Specialist Installations
Residual current circuit breakers monitor the current balance between live and neutral conductors. If an earth leakage fault occurs, the device disconnects the circuit to help reduce the risk of electric shock and protect connected electrical equipment.
Type B RCCBs are used where residual currents may include smooth DC components as well as AC and pulsating DC leakage currents. This makes the ABB F202 B-40/0,03 particularly suitable for installations involving variable speed drives, EV charging equipment, photovoltaic systems, UPS units and other electronic power conversion loads.
Typical Applications
- Commercial distribution boards.
- Industrial control panels and sub-distribution boards.
- Variable speed drive and inverter-fed circuits.
- EV charging and specialist electronic load applications.
- Photovoltaic and UPS-related electrical installations.
- Electrical installations requiring Type B residual current protection.
