Why Choose the ABB F202 AC-40/0,03 AP-R Residual Current Circuit Breaker?
The ABB F202 AC-40/0,03 AP-R 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 trusted ABB F200 series, this 2-pole RCCB helps protect people and installations by disconnecting the circuit when residual current leakage is detected.
This model combines 40 A rated current with 30 mA residual current sensitivity, making it suitable for applications where additional protection against electric shock is required. Its Type AC tripping characteristic is designed for sinusoidal alternating residual currents, while the AP-R high-immunity design helps reduce unwanted tripping in installations affected by transient disturbances.
With a compact 2-module DIN rail format, screw terminals and robust ABB construction, the F202 AC-40/0,03 AP-R is ideal for distribution boards, control panels and electrical protection systems where reliable residual current protection is essential.

Reliable Residual Current Protection for Electrical Installations
Residual current circuit breakers monitor the current balance between live and neutral conductors. When an earth leakage fault is detected, the device disconnects the supply to help reduce the risk of electric shock and electrical hazards.
The ABB F200 series is widely used in electrical distribution systems where reliable residual current protection is required. The AP-R version is particularly useful in installations where transient disturbances, capacitive leakage currents or connected equipment may otherwise cause unwanted tripping.
Typical Applications
- Residential consumer units and distribution boards.
- Commercial electrical installations.
- Industrial control panels and sub-distribution boards.
- Lighting and small power circuits.
- Building services and facilities electrical systems.
- Electrical installations requiring 30 mA residual current protection.
