The UL Listed short-circuit
current rating for Square D
general duty, not fusible
switches is based on the
switch being used in
conjunction with fuses.
Evaluation of non-fusible
switches in conjunction
with molded case circuit
breakers has not been
performed. For
applications requiring
greater protection,
consider using a heavy
duty safety switch. Refer
to UL Listed Maximum
Short Circuit Current
Ratings—AC only—on
page 3-6. If a UL Listed
short-circuit current rating
is required, this non-fusible
switch must be replaced
with a Square D general
duty fusible safety switch
equipped with the
appropriate class and size
fusing. The UL Listed
short-circuit current rating
of the fusible switch is
typically as follows: when
used with Class H and K
fuses—10,000 A, Class R
and J fuses—100,000 A.
Consult the wiring diagram
of the switch to verify the
UL Listed short-circuit
current rating.
b
50 kA for 60 A non-fusible
switch.

General duty safety switches are designed for residential and commercial applications where durability and economy are
prime considerations. Typical loads are lighting, air conditioning, and appliances. They are suitable for use as service
equipment when equipped with a factory- or field-installed neutral assembly or a field-installed service grounding kit, as
applicable.
General duty safety switches are UL Listed, File E2875, and meet or exceed the NEMA Standard KS1. 400 and 600 A
general duty switches (NEMA 1 only) will accept Class J fuses and are UL Listed for use on systems with up to 100 kA
available fault current. 600 A requires Class J fuse kit—GDJK600 (page 3-3). 400 A requires moving load base.
Class T 400–800 A general duty safety switches use 300 Vac Class T fuses and are UL Listed for use on systems with up to
100 kA available fault current.

Heavy Duty Safety Switches

240 Volt
Class 3110
www.schneider-electric.us

Visible blade heavy duty safety switches are designed for application where maximum
performance and continuity of service are required. All heavy duty safety switches
feature quick-make, quick-break operating mechanism, a dual cover interlock and a
color coded indicator handle. They are suitable for use as service equipment when
equipped with a field- or factory-installed neutral assembly or equipment grounding kit,
unless a 600Y/347 V or 480 Y/277 V, 1000 A or greater, solidly grounded WYE system
is used, per NEC 215-10. Heavy duty safety switches are UL Listed (except as noted),
File E2875 and 154828 and meet or exceed the NEMA Standard KS1. For UL Listed
short circuit current ratings, see page 3-6.

MD50 Motor Disconnect Switches
Class 3110
www.schneider-electric.us

The MD50 Motor Disconnect Switch merges three key product features to provide safe,
quick and reliable mating of mobile and fixed motors to power connections. The features
include the UL508 “Suitable for Motor Disconnect” switch, the IEC 60309-2 pin and sleeve
technology, and the mechanical interlock integrated in a rugged plastic enclosure. The
mechanical interlock prevents the making or breaking under load of plug-connected
equipment. The plug must be inserted before the power can be turned “ON”. The plug
cannot be removed until the power is turned “OFF”. The combination of the MD50’s UL508
listing, IEC 60309 technology, and the rugged plastic enclosure, provides a set of features
for motor disconnecting not available in the existing UL98 Receptacle Switch offering.
Grounding and conduit hub included.

Electrical Interlock Kits

Table 3.23:

Electrical interlocks for heavy duty 30–1200 A safety switches are
available factory-installed or in kit form for field installation. Each kit
contains instructions for proper field mounting. A pivot arm operates
from switch mechanism, breaking the control circuit before the main
switch blades break. Switches with electrical interlocks installed are UL
Listed. For factory-installed electrical interlocks add EI (for one contact)
or EI2 (for two contacts) suffix to catalog number. See Supplemental
Digest page 2-4 for electrical interlock contact ratings.

Internal Barrier Kits provide an additional
barrier that helps prevent accidental contact with
live parts. Field-installed transparent barriers do
not restrict visual inspection of the switch.
Barriers provide IEC529 IP2X “finger safe”
protection when door of enclosed disconnect
switch is open. Convenient door allows use of
test probes without accessing fuses and
replacement of fuses without removing barrier.
Barrier can also be used with the skirt kit to
enclose a panel mounted Type 9422 disconnect.

Rating applies to AC only. The UL Listed short circuit current rating for non-fusible switches is based on the switch being used in conjunction with the
corresponding fuse type. Evaluation of non-fusible switches in conjunction with molded case circuit breakers has not been performed.
b
The DTU361 and DTU361RB are also suitable for use on a circuit capable of delivering not more than
(A) 18 kA, 600 Vac maximum when protected by Type FH circuit breaker rated 30 A maximum or
(B) 14 kA, 600 Vac maximum when protected by Type FA circuit breaker rated 30 A maximum.
c
Any brand of circuit breaker or fuse not exceeding the ampere rating of the switch may be used ahead of a non-fusible safety switch when there is up to
10 kA short circuit current available.
d
400 A 82,000 switch is only 10 kA.
