Feature

●Function: the voltage monitoring relay is used to measure and protect the power supply voltage, with phase sequence and phase failure protection, overvoltage and undervoltage protection
●【Voltage monitoring relay】: the voltage protector supports self-reset after a failure, which is very convenient and you can use it without hesitation
●【With LCD display】: voltage monitoring relay with LCD display, real-time display of working data, easy to read, LED display for relay status, easy to judge
●【Easy to install】The phase monitoring relay is small, installed on a standard 35mm guide rail, and uses high-quality pure copper wiring terminals. The wiring is attached and is not easy to loosen, and the service life is long
●Area of application: voltage monitoring relays are used to control mobile devices, field equipment, agricultural equipment and refrigerated vehicles, as well as for controlling and protecting personnel and equipment from the consequences of reverse branches
