| Voltage Sensitive Relays WILMARTM Protective Relays - D101X Series, 3 Phase Adjustable, Close Differential #6 - 32 STUDS 10 PLACES Function: * ANSI/IEEE C37.90-1978 * UL file No. E58048 * CSA file No. LR61158 Close Differential Relays are voltage sensitive. The pick-up and drop-out voltage settings are independently adjustable, which allows precise setting of the differential voltage. This relay is available in a wide range of AC voltages. Their primary application is the sensing and control of transfer switches. H2 Operation: The output contacts will close when the voltage of all three phases is above the pre-set pick-up point, and will open when any one phase drops below its drop-out setting.
