	Monitoring relay (3 phase; voltage; sequence; imbalance) Three-phase relays are adapted for the protection of three-phase receivers against abnormal variations in the mains voltage, against phase failure and phase imbalance, phase coincidence and incorrect phase sequence. They are efficiently applicable for the protection of refrigerating and air-conditioning devices, compressor plants and other equipment with an electric motor load. They are also used in the devices that call for continuous monitoring of mains voltage existence, quality and all-the phases-presence, e. g. in the automatic throw-over circuit-breakers. Hysteresis is about 5V in .... Listed by: NOVATEK-ELECTRO LTD.
