Overview
Outline Dimensions
The WD series offers several different models of protective relays in a
common package that is suitable for either DIN rail or screw mounting.
These flexible, multifunction devices offer user selectable voltages, sense
currents and frequencies. Adjustable time delays are standard. This allows
a single part number to be suitable for multiple applications, thereby reducing inventory costs.

Installation and Maintenance Information
Installation: To mount the WD series protective relay on a DIN rail, hook
the top edge of the cutout on the base of the case over one edge of the
DIN rail, then press the opposite side of the cutout containing the release
clip over the opposite side of the DIN rail. To remove or reposition the relay, lever the release clip and move the relay as required. WD series relays
should be installed in a dry location where the ambient temperature will be
within the operating temperature range.
Maintenance: WD series protective relays are solid state devices that
require no maintenance. They are not designed to be serviced by the user.
Consult KILOVAC customer service at 805-220-2023 if repairs should be
necessary.
