1The UL Listed short-circuit current rating for Square D® general

duty non-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. 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 Classes H

and K fuses—10 kA, Classes J and R fuses—100 kA. Consult

the wiring diagram of the switch to verify the UL Listed short

circuit current rating.

Product Description

The Square D® brand Heavy Duty Safety Switch is designed to be tough,

reliable and provide exceptional performance in the most grueling

conditions; from commercial and institutional to industrial and manufacturing

facilities. Square D F Series safety switches provide significantly higher

levels of mechanical endurance than NEMA KS-1 requires. The design life

of a Square D F-Series switch is a minimum of three times the NEMA

requirement.

An abundance of copper is used in the heaviest current carrying power

paths of all Square D Heavy Duty Safety Switches. The more copper for

current carrying paths, the lower the temperature rise. Managing

temperatures inside the switch is the key to providing greater service life.

All heavy duty safety switches feature a quick-make, quick-break operating

mechanism, a dual cover interlock and a color-coded indicator handle.

Receptacle Switches

Interlocked receptacle switches are furnished with a factory-installed three-

phase four-wire Appleton Powertite®, Crouse-Hinds Style 2 Arktite®, or

Hubbellock™ receptacle. The fourth wire is connected to the switch equipment

grounding terminal and is not a solid neutral termination. Interlocking linkage

between the receptacle and switch mechanism prevents insertion or removal of

the plug while the switch is in the “ON’’ position, or insertion of any plug other

than specified. The interlocking mechanism also prevents the switch from being

turned “ON” if a plug has not been fully inserted into the receptacle.

Lock-Off Guard

Available field-installed only, the lock-off guard works by covering the

lockout/tagout opening whenever the switch is in the ON position. This prevents

a padlock from being inadvertently inserted into the switch lockplate. The

device is designed to help prevent accidental misapplication of a lockout

device. These kits are marked cURus (UL Component Recognized) for field-

installation.

Internal Barrier Kits

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.
