PHASE FAILURE PHASE SEQUENCE RELAY

XJ11(XJ3-D) Overvoltage / Undervoltage / Phase failure / Phase sequence Protection Relay (hereinafter ‘Protection Relay’) , connected with the switching electrical device (like AC contactor etc.) as the protective circuit to do efficient protection for the breakdown which probably occurred by over voltage,under voltage,phase failure,phase sequence in the irreversible 3-phase AC electromotor and transmission equipment( for example water pump,draught fan,conveyer belt,air compressor,feeder line).
