Why Choose the ABB F202 A-40/0,5 Residual Current Circuit Breaker?
The ABB F202 A-40/0,5 is a premium 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 disconnects the electrical supply when dangerous residual currents are detected, helping protect both people and electrical installations.
With a 40 A rated current and 500 mA residual current sensitivity, this device is primarily intended for earth fault and fire protection applications. Its Type A tripping characteristic detects both sinusoidal AC and pulsating DC residual currents, making it suitable for installations containing modern electronic equipment and power supplies.
The compact 2-module DIN rail design, robust screw terminals and ABB's proven engineering make the F202 A-40/0,5 an excellent choice for consumer units, commercial distribution boards and industrial control panels requiring dependable residual current protection.

Reliable Type A Residual Current Protection
Residual current circuit breakers continuously monitor the balance between live and neutral conductors. When an earth leakage fault occurs, the RCCB disconnects the supply to reduce the risk of electrical hazards and protect connected equipment.
Type A RCCBs detect both alternating residual currents and pulsating DC residual currents generated by many modern electronic devices. The 500 mA sensitivity is commonly selected where earth fault and fire protection are required rather than additional personal protection against electric shock.
Typical Applications
- Commercial electrical distribution boards.
- Industrial control panels.
- Main incomer protection.
- Building services installations.
- Electrical installations requiring 500 mA fire protection.
- General Type A residual current protection applications.
