三相四线过压和欠压保护器 JGGQ-80

3 phase 4 wire over and under voltage protector is an upgrade from the ordinary type of product, product features: low power consumption, long life, precise control, phase loss protection, lack of zero line protection, maximum short-circuit limiting current 3000A, software control humanization, and clear indication with Led light, the product is powered on for the first time under normal conditions of the power supply closing time is 6 seconds, when the line occurs over-undervoltage, lack of phase and other faults, when the power supply turns normal, the closing time is 40 seconds, this design saves too much time to wait when the power grid is in the power failure.

导言

三相四线过压和欠压保护器 JGGQ-80S/3P+N It is an upgrade from the ordinary type of product, product technical characteristics: low power consumption, long life, precise control, lack of phase protection, lack of zero line protection, maximum short-circuit limit current of 3000A, software control of humanization, and clear indication with Led light, the product is powered on for the first time under normal conditions of power supply closing time of 5 seconds, when the line occurs undervoltage, lack of phase and other faults, when the power supply turns normal, the closing time is 20 seconds, this design saves too much time to wait when the power grid is out of power.

The 3 phase 4 wireSelf reset table over and undervoltage protectorIt has the functions of phase loss, zero loss, overvoltage and undervoltage protection, and is often used in three-phase four-wire distribution lines and photovoltaic power generation combiner boxes.
