Special Application Heavy Duty Safety Switches
316 Grade Stainless Steel—NEMA Type 3, 3R, 4, 4X, 5, 12
H361SS
316 stainless steel enclosure safety switches offer superior corrosion resistance to a
wider range of chemicals than 304 stainless switches. 316 better resists chloride and is
often used in marine, waste treatment and transportation applications. Use watertight
hubs, see Hubs, page 3-15. Equipment grounding lugs are supplied as standard through
200 A. See Table 3.42 Terminal Lug Data, page 3-21 for wire Termination data for
grounding lugs. (For 304 stainless switches, see 240 Volt, page 3-8 and 600 Volt, page
3-9.

Fiberglass Reinforced Polyester Enclosures—NEMA Type 4X
H363DF
Fiberglass reinforced polyester enclosures are watertight, corrosion resistant, and
impervious to windblown dust, rain, and splashing liquid. The molded fiberglass is
extremely stable in a wide range of operating temperatures and can withstand heavy
impact. Switches are furnished with hubs, conduit provisions Table 3.43, and equipment
grounding lugs. See CAD drawings of the switch to verify the UL listed short circuit
current rating or the enclosed safety switch catalog. UL Listed.
