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. Heavy Duty Safety Switches are utilized 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. This heavy duty Single Throw Safety Switch has a rated current of 600A and has a NEMA 3R degree of protection. This fusible disconnect has a short circuit rating of 200kA@600VAC. This safety switch has a galvannealed steel enclosure and is surface mounted. This product is compatible with H or K, R, J or L fuses. The acceptable AWG gauge for this product is AWG 3/0 / 500 kcmil, copper or aluminum and has a tightening torque of 375-375 lbf.in. This product complies to UL listed file E2875 standards and comes with an 18 month warranty. Dimensions for this product are 50.31 in (H), 27.88 in (W), 10.13 in (D).
