Safety Switches
Product Description
Vol. 1, Ref. No. [0240]
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
For residential and commercial
applications. Suitable for light duty
motor circuits and service entrance.
■
30 – 600 amperes.
■
Suitable for service entrance appli-
cations 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.
■
200 – 600 amperes features
K-series design.
■
Horsepower rated.
■
Fusible and non-fusible switches.
One-pole S/N through 4-wire;
120/240, and 240V AC.
■
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.
Heavy Duty Safety Switches
For heavy commercial and industrial
applications where reliable performance
and service continuity are critical.
■
30 – 1200 amperes.
■
600V AC, 600V DC 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.
■
Suitable for service entrance
applications unless otherwise noted.
■
Visible double break quick-make,
quick-break rotary blade mechanism.
Two points of contact provide a posi-
tive 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 pad-
locked 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.
■

and industrial applications, refer to

our new Mill Duty Safety Switch.
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 two-
speed motors that are remote from their
motor control devices.
■
600V AC, 250V DC maximum.
■
30 – 200 amperes.
■
Fusible or non-fusible.
■
Trunk-type latches keep the cover
tightly closed and a neoprene gas-
ket 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 posi-
tive 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.
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.
■
600V AC, 250V DC 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.
■
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 posi-
tive open and close, easier operation,
and also help prevent contact
burning for longer contact life.
■
Triple padlocking capability. Person-
nel 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.
