Cost-Saving Maintenance
Advanced maintenance features extend switch
life and reduce downtime, saving both labor and
material costs. The Square D safety switch modular
design allows the replacement of all interior worn or
damaged components.
Field-replaceable components such as interior line
bases, load bases, and mechanisms are available.
Moreover, handles and lock plates are also
replaceable if they are damaged or vandalized.
In addition, Square D Type 4X and 12 safety
switches come standard with fuse pullers,
increasing the convenience and safety of
maintenance. Fuse pullers are also eld-installable
on certain models.
Operation and Safety
Nothing is as important in the design of a switch
as understanding how it will be used. To ensure
Square D safety switches continue to meet the needs
of commercial and industrial applications, products are
engineered with the operational procedures and safe
work practices of customers in mind.
Superior Handle Design
The Square D F-Series insulated switch handle is an
industry exclusive. It is made from a high-strength
polymer chosen for weather resistance, durability,
and impact strength.
The two-color, position-indicating handle on heavy-
duty safety switches enhances operator safety by
aiding in visual recognition of switch position from
an angle or at a distance. The simple concept of
having contrasting colors on the handle enhances
the ability of the operator to determine quickly the
position of the switch, even in low-light conditions.
In an emergency, it is vital that switch position be
accurately recognizable. Plus, an embossed on/
off marking is a permanent indication of the switch
position and cannot be removed or vandalized.

Tamper-Resistant Enclosure
Resolving lockout issues is a priority with major
industrials. Square D F-Series safety switches
have an extruded lock plate feature that helps
prevent tampering with lockout devices. The lock
plate opening is extruded to reduce the possibility
of lockout devices being removed by non-
authorized personnel.
With the use of the handle lock plate, the switch
can be locked in the OFF position with up to
three padlocks to comply with OSHA lockout
requirements. The safety switch can also be
modied so that the switch can be locked in the ON
position, if required by the application.
Heavy-duty dual cover interlocks are key safety
features on single-throw and double-throw heavy-
duty switches. These prevent the opening of the
cover when the switch is ON or turning the switch
ON when the cover is open. Qualied personnel can
also defeat this feature allowing them to perform any
necessary testing.
