JVRD voltage phase sequence multi-function protector (three-phase AC protection relay) instruction manual
Protection features: ● Phase protection ● Misphase protection ● Voltage imbalance protection ● Overvoltage protection ● Undervoltage protection
Dimensions: 79H×23W×79D
caveat! This product is generally the power supply side of the three-phase power supply sampling, shall not be installed in the output side of the inverter current!
-JVRD series voltage phase sequence multi-function protector (also known as three-phase power monitor, phase sequence protector, over voltage protection device, etc.) is mainly used for AC 50/60Hz, rated voltage below 460V, industrial three-phase 220V, 380V, 440V, 460V and other voltage levels of various fault detection, the three-phase input power supply voltage is too high, voltage is too low, lack of phase, reverse phase (phase sequence), three-phase voltage imbalance, etc. to provide protection relay
 
-products widely used For air compressors, motors, distribution boxes, pumps, oil pumps, central air conditioning units, electric control boxes, power distribution cabinets, cranes, etc., such as central air conditioning compressor protection, power monitoring of various elevators, water pump, oil pump protection phase The reverse phase protection is an indispensable protection product that maintains the normal working voltage of the equipment during operation of industrial equipment
Installation method : The protector base adopts rail type, and has two M4 screw holes structure. It is directly installed independently or HT35 rail is installed (if direct installation is adopted, the bottom two attachments of the product must be pushed out forcefully).
Indicator lights : 5 indicators to indicate: normal, missing phase (voltage three-phase unbalanced), reverse phase, overvoltage, undervoltage.
Overall dimensions : 79mm x 23mm x 79mm.
Contact form : two open and two closed
