FAR6-U series self resetting overvoltage and undervoltage protectorDetailed product description：

The FAR6-U series self resetting overvoltage and undervoltage protector adopts a small circuit breaker with short-circuit overload protection as the main switch, equipped with an ultra small intelligent electric operation with a microprocessor, to detect the power supply voltage and achieve overvoltage or undervoltage tripping protection, as well as automatic reclosing after voltage recovery, ensuring the safe operation of load equipment under normal voltage. Mainly suitable for situations where the voltage of the power grid is unstable or for protecting equipment that is sensitive to voltage fluctuations.

Complies with the requirements of JGJ242-2011 "Code for Design of Residential Buildings" for self resetting overvoltage and undervoltage protectors
Compliant with GB10963.1 Overcurrent Protection Circuit Breakers for Household and Similar Places Part 1: Circuit Breakers for AC Use
