HGQ2 Series Dual Power Automatic Switching SwitchDetailed product description：

Purpose:
The HGQ2 series dual power automatic switch is suitable for two power supplies (common power supply and backup power supply or power generation power supply) with AC 50HZ, 690V and below. It automatically switches between power supplies in case of a failure of one power supply to ensure the reliability and safety of power supply.

This product has two switching functions: self switching and self resetting, and self switching and non self resetting. It can simultaneously detect the three-phase power supply of two power sources in a three-phase four wire power grid. When any one of them experiences overvoltage or undervoltage (including phase loss), it will automatically switch from the abnormal power supply to the normal power supply; The product used in the power generation system of the power grid also has power generation and unloading signals, making it a dual power automatic switching product with complete performance, safety and reliability, automation level, and wide range of applications. This product complies with the IEC60947-6-1 (1989) standard for automatic transfer switch circuit breakers.
