GMR-32B Phase Sequence Relay,380VAC Voltage Over Under Voltage Phase Failure Relay,Guide Rail Voltage Phase Loss Protector Monitoring Relay

Mainly used for AC 50/60Hz, rated voltage 460V or less, industrial three-phase 220V, 380V, 440V, 460V and other voltage levels of various fault detection, and provide relay for the voltage of the three-phase input power supply is too high, the Products are widely used in air compressors, electric 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, The protector base adopts rail type and has two M4 screw hole structures, which can be directly installed separately or HT35 rail mounting (if direct installation is required, the accessories on both sides of the bottom of the product should be pushed ou The error is indicated by 5 indicators: normal, phase loss (voltage three-phase unbalance), reverse phase, overvoltage, undervoltage. The connecting wire of the main circuit: the insulating copper wire has a carrying area of 1.0~2.5mm. The single strand of copper wire can be directly inserted into the terminal;a needle type terminal must be added to the wire to ensure connecti
