Voltage protection relay Three Phase Voltage Monitoring Relay air conditions phase protector
Three-phase power supply monitor, phase failure protector, over-voltage protection, etc. are mainly used for various fault detection of AC 50/60Hz, rated voltage below 460V, industrial three-phase 220V, 380V, 440V, 460V and other voltage levels. Provides relay protection for three-phase input power supply voltage is too high, voltage is too low, lack of phase, reverse phase (phase sequence), three-phase voltage imbalance, the product is widely used in 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, pumps, oil pumps against phase loss, reverse phase protection, etc., are maintenance of industrial equipment during operation An indispensable protection product with normal operating voltage.
