Voltage Sensitive Relays WILMAR™ Protective Relays – D100X Series, Close Differential Function: • ANSI/IEEE C37.90-1978 • UL file No. E58048 • CSA file No. LR61158 0.5 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 and DC voltages. Their primary application is the sensing and control of transfer switches. Operation: See Part Number Selection Monitors a single phase AC signal, and is used for undervoltage detection. Has separate pick-up and drop-out voltage settings, providing an adjustable hysteresis. 2.6 6 3.0 5 3. 2.2 50 3 11/ 64" DIA. 4 MTG. HOLES Note: Dimensions in inches.

AC, Single Phase, see part number selection Nominal Frequency .......................... 50 to 400 Hz. Pick-Up Adjustment Range ............. 67-100% of nominal voltage Drop-Out Adjustment Range ........... 67-100% of nominal voltage Maximum Differential Setting .......... 33% of nominal voltage Minimum Differential Setting .......... 2% of nominal voltage Output Contacts ............................... Form C (SPDT) Contact Ratings ................................ 5 Amp resistive at 120 VAC or 28 VDC Operating Temperature Range ........ -20°C to +85°C Expected Life .................................... 10 million operations Inverse Time Drop-Out: The differential relay contains a time delay before operation so that momentary voltage transients do not aftect the operation of the relay. The time delay has an inverse time characteristic so that excessive voltage conditions will cause a more rapid dropout. This time delay is approximately 200mSec. (12 cycles) at the trip settings and decreases to 30 mSec. at approximately 15% beyond the trip settings. PART NUMBER SELECTION Sample Part No. D100X Model: L-L Volts D100X = 120 VAC D100-6X = 120 VAC, Spike Suppression D100-3X = 208 VAC D100-4X = 240 VAC D100-8X = 277 VAC D100-5X = 480 VAC D100-7X = 510 VAC Surge Withstand Capability is in compliance with the requirements of ANSI/IEEE C37.90B Notes: 1. Remove black nylon protective screws to gain access to the two internal adjustment potentiometers. 2. Clockwise rotation of the pick-up and drop-out adjustment will raise the voltage trip point. 3. The relay contacts are shown in the de-energized state.
