Application

General Duty Heavy Duty Double Throw

General Duty Switches are intended for

applications where reliable performance and

continuity of service are needed, but where

duty requirements are not severe and usual

service conditions prevail. (These switches are

intended for use primarily with supply

circuits rated 240V AC or less where the avail-

able fault current is less than 100,000A when

used with Class R or T fuses or 10,000A max.

when used with Class H fuses.)

Suitable for use on systems capable of

delivering not more than 100,000 RMS

symmetrical amperes of fault current as

follows:

Sw. Rating AIC Rating Protective Device

30-600A 10,000 Circuit Breaker

30-600A 10,000 Class H Fuse

30-600A 100,000 Class R Fuse

100-600A 100,000 Class J or T Fuse

Fusible switches will accept the following

UL class fuses:

30 “LF” - 30A max plug Fuses

30-600A “GF” Class H & K, Class R with kit

100-600A “GF” Class J-move base

100-200 “GF” Class T with kit

400-600A “GF” Class T-move bases

Voidable – cover interlocks on switches pre-

vent the switch door from being opened when

in the “ON” position. No cover interlock on

30A Type 3R or on plug fuse type switches.

Heavy Duty Switches are intended for use in

applications where:

Rugged construction, reliable performance,

continuity of service and ease of mainte-

nance are emphasized, or

ailable fault currents higher than 10,000A

are likely to be encountered, such as in

manufacturing plants, mass production

industries, and commercial, institution-al and

other large buildings served by network sys-

tems or transformers of higher capacities.

System voltage is 600V AC or DC Max.

Type 12 or 4 / 4X enclosure is required.

Suitable for use on systems capable of delivering not more than 200,000 RMS symmetrical

amperes of fault current as follows:

All switches (both Fusible and Non-Fusible)

are either supplied with factory installed neu-

trals or accept field addable neutrals.

Listed by UL under file #E4776 as enclosed switches and also suitable for use as service equipment (where applicable).

UL98 Enclosed and Deadfront Switches.

All GD & HD switches and “DT” type double throw switches have been tested and comply with the 2010 California Building Code (CBC)

and with the 2009 International Building Code (IBC) - Compliance Level SDS = 1.85 g

Meet NEMA standard KS-1-2001 for type GD

switches.

Fusible switches will accept the following

UL class fuses:

30-600A “HF” Class H & K, Class R with kit

30-600A, 600V “HF” Class J-move base

100-600A, 240V “HF” Class J-move base

400-600A “HF” Class T-move bases

800-1200A “HF” Class L, Class T with kit

Padlockable cover latch. OFF padlock

provisions on handle.

Double throw switches are intended to

transfer loads from one power source to

another. All 2 & 3 pole double throw switches

are suitable for use as service equipment. All

are UL Listed. Switches are rated for use on

systems with an available fault current of up

to 10,000 AIC when protected with Class H

fuses or either 100,000 or 200,000 AIC when

protected with Class R, J or Class T fuses. They

can also be used to connect a single source of

power to either of two loads, In this application

it is necessary to field modify fusible switches

so that the fuses are on the load side of the

switching mechanism.

Voidable dual cover interlocks standard on

all heavy duty switches. Prevents cover from

being opened when switch is in the “ON”

position and prevents switch from being

turned “ON” when door is opened.

Meet NEMA standard KS-1-2001 for type HD

switches.

Padlockable cover latch and multiple OFF pad-

lock provisions on handle.

Padlockable cover latch and multiple

F pad-

lock provisions on handle.

Dual cover interlocks standard on all double

throw switches. Prevents cover from being

opened when switch is in the “ON” position

and prevents switch from being turned “ON”

when door is opened.

Meet NEMA standard KS-1-2001 type GD

for “DTG” & type HD for “DT”, “F” & “NF”

switches.

All except 4 pole switches will accept field

addable neutrals except that “DTG” 100 &

200A switches are also available with factory

installed neutrals.

Fusible switches will accept the following

UL class fuses:

30-200A “DT” & “F” Class H & K, Class R with kit

30 & 60A 600V “DT” Class J-move base

100-200A “DT” Class J-move base, Class T with kit

400-600A “DT” Class J-standard, Class T-move bases

400A 240v “F” Class H-standard

400A, 600V & 600A “F” Class T-Standard

Fusible switches have groundable neutral

blocks factory installed. Non-fusible switches

accept field addable neutrals.

All General Duty, Heavy Duty and Double Throw Switches are both load break and horsepower rated.

The protective device can either be a fuse installed in a

fusible switch or an upstream fuse or circuit breaker

protecting a non-fusible switch. The ampere rating of the

upstream protective device must not exceed the switch

ampere rating.

All 4 pole and fusible double switches with catalog num-

bers starting with “F” are rated 100,000 AIC max.

Class T kit available for 240V max. applications on 1200A

switches.
