latch or handle to be closed, latched, and engaged before the
disconnect is restored. - It provides protection from dirt, dust, oil, and water.
The EXR enclosure is available in two models:
- SCE-EXR12-30T200: This model is compatible with Compact Fusible

Product Usage Instructions:
For installation of the EXR to a Free Standing Enclosure
(Disconnect Enclosure), the following tools will be required:
- Phillips Screwdriver
- 7/16, 11/32, & 3/8 WRENCH
- WIRE CUTTERS
- NEEDLE NOSE PLIERS
- ADJUSTABLE WRENCH
To install the EXR onto the main enclosure, follow these
steps:
- First, drill the mounting pattern into the right side of the
main enclosure. - Next, use the disconnect cover plate to line up the clearance
hole drilling location for the quarter turn. The disconnect cover
plate, quarter turn, and nuts will connect to the upper assembly
and hold it in place. - Apply the gasket to the left side of the EXR enclosure outside
the holes to ensure a proper seal. - Use the 128550 master bolt pack to install the EXR to the main
enclosure. Note: There is a keyway cutout on the mounting
provisions to ease installation.
With the EXR now installed onto the main enclosure, the
interlock can be installed as follows:
- Attach the EXR assembly to the stud on the inside wall of the
EXR. - Install the Defeater cable and crimp it to lock into place as
shown in Detail C. - Attach the EXR mechanical defeater rod guide with keps nuts
using the PEMs from the disconnect cover plate. - Insert the quarter turn from the outside of the enclosure with
the earth nut. - Attach the EXR disconnect hook arm to the quarter turn.
