Product Description
Product Description
Used to open or close a circuit.
■
■
Non-fusible safety switches provide
a means to manually connect or
disconnect the load from the source.
Fusible safety switches provide a
■
means to manually open and close
a circuit and overcurrent protection
by means of installed fuses.
Also commonly referred to as a
■
disconnect switch or disconnect.
■
Available from 30 – 1200 amperes.
Application Description
General Duty
Plug Fuse
General-Duty
Safety Switch
For residential and commercial
applications. Suitable for light-duty
motor circuits and service entrance.
30 – 600 amperes.
■
■
Suitable for service entrance applications unless otherwise noted.
■
Fusible and non-fusible switches
are 100% load break and 100%
load make rated.
The continuous load current of
■
fusible switches is not to exceed
80% of the rating of fuses employed
in other than motor circuits. Nonfusible switches are 100%
fully rated.
■
200 – 600 amperes features
K-series design.
■
Horsepower rated.
Fusible and non-fusible switches.
■
One-pole S/N through 4-wire;
120/240, and 240 Vac.
■
Ample wire bending space provides
for easier installation.
■
With Class R fuses, switches may be
used on systems capable of delivering
100,000 amperes rms symmetrical.
Note: Plug fuse switches are not service
entrance rated.
Cartridge Fuse
General-Duty
Safety Switch
Heavy Duty
Heavy-Duty Safety Switches
For heavy commercial and industrial
applications where reliable performance
and service continuity are critical.
■
30 – 1200 amperes.
600 Vac, 600 Vdc maximum.
■
■
Horsepower rated.
Fusible and non-fusible switches
■
are 100% load break and 100%
load make rated.
■
The continuous load current of
fusible switches is not to exceed
80% of the rating of fuses employed
in other than motor circuits. Nonfusible switches are 100%
fully rated.
■
Suitable for service entrance
applications unless otherwise noted.
■
Visible double break quick-make,
quick-break rotary blade mechanism.
Two points of contact provide a positive open and close, easier operation,
and also help prevent contact
burning for longer contact life.
■
Triple padlocking capability.
Personnel safety feature since the
large hasp can accommodate up to
three 3/8-inch (9.5 mm) shank locks.
Cabinet door can be further padlocked at the top and bottom.
Interlocking mechanism. Door can-
■
not be opened when the handle is
in the ON position. Built-in defeater
mechanism provides for user access
when necessary.
■
For the toughest heavy commercial
and industrial applications, refer to
Page 8-47 for catalog information on
our Mill-Duty Safety Switch.
■
Deionizing arc chutes. Arc chutes
confine and suppress the arcs
produced by opening contacts
under load.

6-Pole Switches
6-Pole Motor Circuit
A compact safety switch that’s ideal for
use in heavy industry...when an “in sight”
disconnecting means is required for twospeed motors that are remote from their
motor control devices.
600 Vac, 250 Vdc maximum.
■
■
30 – 200 amperes.
Fusible or non-fusible.
■
■
Trunk-type latches keep the cover
tightly closed and a neoprene gasket seals out moisture and dust from
the switch assembly.
■
Visible double break quick-make,
quick-break rotary blade mechanism.
Two points of contact provide a positive open and close, easier operation,
and also help prevent contact burning
for longer contact life.
Clear line shield protection.
■
■
Built-in fuse pullers.
Clearly visible handle.
■
■
Triple padlocking capability. Cabinet
door can be further padlocked at the
top and bottom.
Deionizing arc chutes. Arc chutes
■
confine and suppress the arcs
produced by opening contacts
under load.

Double Throw Switches
Heavy-Duty Double Throw
Used to transfer service from a normal
power source to an alternate source...or
to switch from one load circuit to another.
■
30 – 800 ampere switches are
horsepower rated.
■
600 Vac, 250 Vdc maximum.
■
Fusible or non-fusible.
Fusible and non-fusible switches
■
are 100% load break and 100%
load make rated.
■
Suitable for service entrance
applications unless otherwise noted.
■
The continuous load current of
fusible switches is not to exceed
80% of the rating of fuses employed
in other than motor circuits. Nonfusible switches are 100%
fully rated.
Approved for service entrance with
■
neutral or ground lug kit installed.
Wiring configuration from factory
■
allows a single load to be supplied
by a normal or alternate source.
Can be field modified to allow two
loads to be alternately supplied by
a single power source.
■
Non-fusible double throw switch
can be used to feed a single throw
fusible switch, the normal method
to provide manual transfer from
one power source to another in
800 ampere and larger switches.
Ample wire bending space provides
■
for easier installation.
Visible double break quick-make,
■
quick-break rotary blade mechanism.
Two points of contact provide a positive open and close, easier operation,
and also help prevent contact
burning for longer contact life.
■
Triple padlocking capability. Personnel safety feature since the large
hasp can accommodate up to three
3/8-inch (9.5 mm) shank locks.
■
Clearly visible handle. The position
(ON or OFF) can be clearly seen
from a distance.

Product Description
■
Deionizing arc chutes. Arc chutes
confine and suppress the arcs
produced by opening contacts
under load.
■
Additional locking capability.
Cabinet door can be further padlocked at the top and bottom.
■
Clear line shield (provided on fusible double throw) protects against
accidental contact with energized
parts. Probe holes enable the user
to test if the line side is energized
without removing the shield.
■
Tangential knockouts on sides,
top and bottom. Enables any size
of conduit to be mounted close
to the wall, providing for cable
installation closer to the wall
and a neat appearance.
■
listed switching neutral capability
is available on 3-pole and 4-pole
non-fusible double throw switches
with the installation of the proper
bonding kit shown on

EnviroLine
EnviroLine
Eaton offers a line of Cutler-Hammer
safety switches designed for your special
application and/or extreme environmental
conditions.
EnviroLine Stainless Steel Switch —
■
Primarily for use in the meat packing and food processing industries
or any application where water is
frequently used to hose down
equipment. In addition to the stainless steel NEMA 4X enclosure, the
interior mechanism, backpan, and
springs are stainless steel. Ratings
for these heavy-duty switches are
30 – 400 amperes, 240 – 600 Vac,
available as fusible and nonfusible switches.
■ Window Switches — The new
enlarged window on 30 – 100 ampere
ratings allows visual blade position
verification and blown fuse indication without opening the door.
Higher ampere ratings continue to
use the Upper and Lower window
design. The Upper window switch
provides visual verification of ON/
OFF status (blade position), while
the Lower window design shows
fuse status on fuses with blown fuse
indicators. Overall ratings are 30 –
800 amperes, 240 – 600 Vac, fusible
and non-fusible. Available in NEMA
12/3R, 4X stainless steel enclosures.
