CQGQ1-100 Series Self-Resetting Over-Under Voltage Protector

The CQGQ1-100 series automatic voltage protector is a cutting-edge product developed by CHAC Electric to safeguard electrical systems from voltage abnormalities. Designed for circuits with a rated voltage of 230V/400V and a frequency of 50Hz, it can handle a rated working current up to 100A. When over-voltage or under-voltage occurs in the power supply lines, the protector swiftly and safely interrupts the circuit under sustained high voltage impacts, preventing abnormal voltages from damaging terminal electrical appliances and causing accidents. Once the voltage returns to the normal range, the protector automatically reconnects the circuit within a specified time, ensuring that terminal appliances resume normal operation even in unattended situations.

Product Overview

This makes it ideal for protecting single-phase electrical equipment in residential distribution lines or wherever single-phase voltage protection is needed, especially in cases of neutral line faults. The CQGQ1-100 series combines advanced technology with reliable performance, offering a smart and efficient solution for voltage protection. Its automatic recovery function minimizes the need for manual intervention and ensures continuous protection and uninterrupted power supply to critical appliances.
