Voltage Sensitive Relays

WILMAR™ Protective Relays – D100X Series, Close Differential

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 indepen-

dently adjustable, which allows precise setting of the

differential voltage. This relay is available in a wide

range of AC and DC voltages. Their primary applica-

tion 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.

3.125"

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

Contact Ratings ................................ 5 Amp resistive at 120 VAC or 28 VDC

Operating Temperature Range ........ -20°C to +85°C

Notes:

Expected Life .................................... 10 million operations

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.

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 drop-

out. This time delay is approximately 200mSec. (12 cycles) at the trip settings and

decreases to 30 mSec. at approximately 15% beyond the trip settings.

Consult factory for additional models.
