Heavy Duty Safety Switches Class 3100
Heavy Duty Safety Switches
Product Description
Series F
The Square D
™
by Schneider Electric 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.
F Series safety switches provide significantly higher levels of mechanical endurance
than NEMA Type KS-1 or UL98 standards require. The design life of a 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 by Schneider Electric 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.
