• The switch enclosure covers are
interlocked with the body and operating
mechanism and cannot be opened when
the plug is engaged and the switch is
closed ("ON"). When the switch is open,
the switch cannot be put in a closed
("ON") position with the door open.
Applications:
Standard Materials:
• The WSR and WSRD disconnect
switches are used as a service outlet for
portable or fixed electrical equipment –
generators, compressors, welders, etc.
WSR and WSRD/WSRDW:
• Receptacle housings and plug exteriors
– copper-free aluminum
• Insulation (plug and receptacle) –
fiberglass-reinforced polyester
• Pressure contacts – brass
• They are designed for use in non-
hazardous areas where dust, moisture
and corrosion may be a problem.
• Designed for flush or surface mounting.
• A fusible type switch, when used, also
provides short circuit protection.
WSR:
• Mounting lugs may be rotated 90° or
moved to the vertical centerline portion
for pole mounting.
• Side hinged covers are retained in a
closed position by compression spring
draw-pull catches, which permit the
opening or closing of the cover without
tools.
• Crimp/solder contacts – leaded red
brass
WSR:
• Enclosure – copper-free aluminum
• Operating handle – copper-free
aluminum
Features:
WSR and WSRD/WSRDW:
• Other exterior parts – stainless steel
• Switches are NEMA type HD heavy duty
3-pole, with visible blades; a quick
make-and-break mechanism with
reinforced, positive pressure type blade
and jaw construction. Fusible types have
fuse clips with steel reinforcing springs
of positive pressure type. Pressure
connectors are used for wire
WSRD/WSRDW:
• Enclosure – sheet steel
• Operating handle – sheet steel
• Other exterior parts – stainless steel
• The switch operating handle may be
padlocked in the "ON" or "OFF"
position, thereby preventing
unauthorized operation of the switch
and/or opening of the enclosure. Up to
three padlocks may be used. In addition,
a unique hinge arrangement has been
devised to allow the door of the unit to
be padlocked. This feature allows
operation while preventing unqualified or
unauthorized entry.
Standard Finishes:
• Copper-free aluminum – WSR enclosure,
plug exteriors – natural
• Leaded red brass – electro-tin-plate
• Brass – natural
• Sheet steel – baked grey enamel
• Fiberglass-reinforced polyester – natural
(red)
connectors.
• For maximum safety, the spring door
receptacle at the bottom of the unit is
mechanically interlocked with the switch
operating mechanism. The switch
cannot be closed until the plug is fully
inserted and the plug cannot be
withdrawn or inserted unless the switch
is open. With the switch open,
accidental plug withdrawal is prevented
by the interlock mechanism. Withdrawal
can only be accomplished by activation
of the interlock release lever located on
the receptacle.
