600 Vac, 250 Vdc, 30, 60, 100 Amp, 50/60 Hz, Fused and Non-fused for use with Powertite™ ACP and CPH plugs.

NEC/CEC :

NEMA 3, 3R, 4, 4X, 12

Applications

• Designed for use in raintight or watertight, non-hazardous,
heavy duty applications where a service outlet is required for
portable or xed electrical equipment such as:

— Welders
— Generators
— Compressors
— Infrared ovens

— Batch feeders

— Conveyors
— Truck terminals
— Marine docks

• Ideally suited for use in industrial plant applications such as:

— Automotive and steel processing plants
— Pulp and paper processing plants
— Milk processing plants and creameries
— Fabrication yards and shipyards
— Refrigerated truck terminals

Features

• For use where an interlocked disconnect switch is desired to

control a Powertite™ receptacle and insertion or removal of

plug. Interlock prohibits plug insertion or removal under load.
Plug is secured in place by interlock and cannot be withdrawn
unless interlock release lever is actuated.

• Spring door standard and screw cap provided at no additional
cost to meet NEMA 3, 3R, 4, 4X applications.

• The Square D  F-Series offers the latest in switch technology:

An operating mechanism designed to endure at least three

times the number of operations required by NEMA and UL
standards; modular componentry designed for quick and easy
maintenance; and visible blades for an extra measure of safety

while the low mass cam allows greater blade operating speed
and reduced mechanical wear.

• Insulated, dual-color polymer operating handle clearly indicates

the switch being energized. Ergonomically designed handle

is made of high-impact polymer material for exceptional
ruggedness, durability and corrosion resistance .

• Utilizes Style 2 (shell and extra pole) grounding and 3-wire,
4-pole receptacle wiring.

• Removable hinged cover allows for ease of installation and
maintenance.

• Class J fusing standard on WSR. Product can be retrotted with
Class J, K, or S fusing.

• Short circuit withstand rated to 200,000 RMS symmetrical Amps
(Class R and J Fusing).

• Stainless Steel captive spring out quad lead cover bolts for easy

access and corrosion resistance.

• Conduit entry is drilled and tapped to 1-1/2”. Reducer bushings
1-1/2” – 1-1/4” and 1-1/2” – 1” provided at no additional cost.

• Stainless steel key-hole mounting feet for easy installation.

• Unit is equipped with defeatable door interlock which allows

emergency access when switch is energized.

• Cover can be padlocked closed.

• Operating handle can be locked in the ”OFF” or ”ON” position.

• Dead front design: receptacle is not energized until plug is fully
inserted and switch is engaged.

• Wire size for 30 and 60 Amp models is #14 to #2 AWG.
For 100 Amp models it is #14 to #1/0 AWG.

Standard Materials and Finishes

• Receptacle assembly: copperfree (4/10 of 1% max.) aluminum
with epoxy powder coating inside and outside

• WSR enclosure: copperfree aluminum with epoxy powder

coating inside and outside

• Operating handle : high impact polymer

• WSR hardware: stainless steel

Options

• Special polarization prevents plug insertion in a receptacle wired

for a different voltage. In installations where there are different

line voltages, the special polarization option is desirable.

This allows only plugs and receptacles wired for the same
line voltage to be mated together. The receptacle interior is

positioned 22-1/2°, relative to the polarization rivet, to the right
(as specied) of standard, and plug is polarized to correspond.
Add sufx -P4 to the standard receptacle.

• Reverse Service: useful where a ”hot” plug feeds a dead

receptacle. Reverse service is often used for generator
applications where the receptacle houses a dead plug

interior. Plug houses an energized receptacle interior, which

has recessed male contacts to reduce danger of accidental
touching. Add sufx -RS to receptacle or connector.
