Description
The H366N is a Schneider Electric safety switch (heavy duty, fusible, 600A, 4 wire, 3 pole, 1 neutral, 500hp, 600VAC/DC, NEMA 1).
Heavy Duty Safety Switches are utized 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.
