Function:

The ASJ10-GQ series automatic voltage protector (hereinafter referred to as ASJ) is suitable for single-phase AC voltage of 230V or three-phase voltage of 400V, with a frequency of 50Hz, for users or loads with rated working current up to and including 63A. The protector protects electrical equipment when there is over or under voltage in single-phase or three-phase lines caused by neutral line faults.

The ASJ series integrates overvoltage and undervoltage protection functions, as well as automatic delay reset for normal line voltage. Mainly applied to the protection of distribution lines for residential sub-metering boxes or single-phase or three-phase power equipment, this product features a small size, high precision, compact structure, and easy installation, making it a safety protection device in the civil construction field.
