CONTROLS CONTROLS WRL SERIES PHASE CONTROL RELAY UL listed CSA recognized * Monitors Phase Sequence Loss of Any Phase even if Induced Voltage reaches 95% of Nominal Voltage * Under Voltage Detection * Trip Delay Timer Built-in * LED Relay Status Indicator 2 MODE OF OPERATION: The WRL Phase Control Relay monitors the sequence loss or reversal of three phase power supplies. The output relay is energized when the phase sequence is correct and the phase voltage is above the voltage threshold set by the front knob. The output relay will de-energize after 2 seconds (built-in timer) when the phase voltage drops under the voltage threshold or when phase sequence is lost. The WRL Series is available in three voltage ranges: 230 VAC, 380 VAC and 480 VAC. SPECIFICATIONS: Input Power . . . . . . . . . . . . . . ....................... .......................

The output relay is energized when the phase sequence is correct and is de-energize when the phase sequence is wrong or one phase is lost. It monitors the symmetry of 3 voltages and a loss of phase even when the voltage is reinjected through a machine. The rate of asymmetry is controlled between 5% and 15% by a top mounted potentiometer.
