Protective Relays 1000 Series Product Facts TERMINAL STRIPS #6 - 32 SCREWS n Function 47 n ANSI/IEEE C37.90-1978 n UL File No. E58048 n CSA File No. LR61158 R R Phase failure relays protect motors, equipment and personnel from damage or injury caused by open phase, reversed phase sequence, or low voltage in a three phase system. Models are available for 50 and 60 Hz with voltages up to 575 volts. Motor control switchboards are a common application. 2 Notes: 1. Remove screw for access to the undervoltage adjustment. 2. Clockwise rotation of the adjustment potentiometer will raise the drop-out voltage. 3/4 1/2 3 11/64" DIA. 4 MTG. HOLES 11 Protective Relays Note: Dimensions in inches. Multiply values by 25.4 for dimensions in mm. 100 90 Drop Out Time Delay The relay contacts will remain in their normally open position (de-energized) when voltage with incorrect phase sequence is applied, one or more phases are open, or at undervoltage condition. 3.0 1 /2 3 /8 7 3 Operation The contacts of the relay will close only when it senses normal conditions of three phase power at the proper phase sequence. 3 13/16 Product Specifications Nominal Voltage — See Ordering Information Voltage Drop-Out — 75% to 100% of nominal, screwdriver adjustable Pick-Up to Drop-Out Differential — 3% approx.
