UGR Receptacle
FEATURES-SPECIFICATIONS
The ACCEPTOR® UGP/UGR Plug and
Receptacle system, with its unique, patented
design, is interchangeable with other
NEMA bladed type explosion-proof and
dust ignition proof devices. The series has
been tested and classified for use with
Crouse-Hinds
U-Line
locations.
versions. See pages PR20-PR21
How The Acceptor System Works
ACCEPTOR receptacles contain an integral
switch which must be closed to energize the
circuit. The design permits only an approved
plug to be energized. To actuate the switch,
the plug must be inserted and rotated
clockwise approximately 45°. The plug will
lock into this position preventing accidental
disengagement. To remove, simply push in
then turn the plug counterclockwise and pull
straight out.
Plugs and receptacles may be used where
interchangeable bladed devices are needed
in locations made hazardous by the presence
of flammable gases or vapors, combustible
dusts or easily ignitable fibers and flyings.
Plug can serve to provide power for portable
equipment used in both hazardous and nonhazardous areas.
