Introduction<\/strong><\/h2>\n
\n

Three phase four wire over and under voltage <\/a>protector JGGQ-80S\/3P+N\u00a0 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.<\/span><\/p>\n

The three-phase four-wireSelf-resettable over\/undervoltage protectorIt has the functions of phase loss, zero loss, overvoltage<\/a> and undervoltage protection, and is often used in three-phase four-wire distribution lines and photovoltaic power generation combiner boxes.<\/p>\n
