ABJ1-14W Three phase AC protection relayDetailed product description：

The ABJ1 series three-phase AC protection relay (also known as three-phase power monitor, phase sequence protector, over-voltage protector, etc.) is 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. It provides relay protection for high voltage, low voltage, phase loss, reverse phase (phase sequence), three-phase voltage imbalance, etc. of the three-phase input power supply. The product is widely used in air compressors, electric motors, distribution boxes, water pumps, oil pumps, central air conditioning units, electrical control boxes, distribution cabinets, cranes, etc., such as central air conditioning compressor protection, power monitoring of various elevators, water pumps, oil pumps anti phase loss, reverse phase protection, etc. It is a maintenance equipment for industrial equipment operation. An essential protective product for normal working voltage.

ABJ1-14W three-phase AC protection relay complies with GB14085.5-2001 eqv IEC60947-1:1999 standard.
Warning! This product is generally used for sampling the power side of three-phase power supply and should not be installed on the output side of variable frequency current
