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 voltages. Their primary application is
the sensing and control of transfer switches.

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.

1. Remove screws for access to pick-up and drop-out
trip adjustments.
2. Clockwise rotation of the pick-up and drop-out
adjustment will raise the voltage trip point.
