ABB F202 AC-40/0,5 residual current circuit breaker from the F200 series, a 2 pole Type AC RCCB rated at 40 A with 500 mA residual current sensitivity for DIN rail electrical distribution applications.
£178.12
The ABB F202 AC-40/0,5 is a reliable residual current circuit breaker (RCCB) designed to provide dependable protection against earth leakage faults in electrical distribution systems. As part of the trusted ABB F200 series, it helps protect people and installations by detecting fault current to earth and disconnecting the circuit when the rated residual current threshold is exceeded.
This 2-pole Type AC residual current device is suitable for single-phase AC systems where protection against sinusoidal alternating residual currents is required. With a 40 A rated current and 500 mA residual current sensitivity, it is well suited for commercial, industrial and building services applications requiring robust earth fault protection.
The ABB F202 AC-40/0,5 features a compact modular design for DIN rail mounting, making it easy to install in distribution boards, switchboards and control panels. Its screw terminal connections and ABB engineering support secure installation and long term performance in demanding electrical environments.
Residual current circuit breakers monitor the balance between live and neutral conductors. If earth leakage current is detected, the RCCB disconnects the circuit to help reduce the risk of electric shock, insulation fault damage and fire hazards caused by residual current faults.
The ABB F202 AC-40/0,5 is designed for installations requiring dependable residual current protection without integrated overcurrent protection. It should be used alongside suitably rated circuit breakers or protective devices to provide complete circuit protection.

The ABB F202 AC-40/0,5 is used to provide residual current protection in electrical installations by detecting earth leakage faults and disconnecting the circuit when required.
This RCCB has a rated current of 40 A, making it suitable for protected single-phase distribution applications.
The F202 AC-40/0,5 has a rated residual current sensitivity of 500 mA.
Type AC means the device is designed to detect sinusoidal alternating residual currents commonly found in standard AC electrical circuits.
No. This is a residual current circuit breaker and does not provide overcurrent or short-circuit protection. It should be installed with suitable circuit protection devices.
ABB F200 series residual current devices are widely used by electrical contractors, panel builders and facilities engineers for reliable earth fault protection in commercial and industrial installations.
