HOLES Protective Relays 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. 4 Close Differential Relays are voltage sensitive. The pickup 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. Nominal Voltage — AC, Three Phase, see Ordering Information Nominal Frequency — 50 to 500 Hz. Pick-Up Adjustment Range — 66-100% of nominal voltage, screwdriver adjustable Drop-Out Adjustment Range — 66-100% of nominal voltage, screwdriver adjustable Output Contacts — SPNO Contact Ratings — 5 amp resistive at 120 VAC or 28 VDC Operating Temperature Range — -20˚C to +85˚C Note: Dimensions in inches. Multiply values by 25.4 for dimensions in mm.
