Heavy Duty Safety Switches–Special

Applications

Class 3110

316 Grade Stainless Steel—NEMA 3, 3R, 4, 4X, 5, 12

Type 316 stainless steel enclosure safety switches offer superior corrosion resistance to a wider range of chemicals than Type 304 stainless switches. Type 316 better resists chloride and is often used in marine, waste treatment and transportation applications. Use watertight hubs from page 3-9. Equipment grounding lugs are supplied as standard.
(For Type 304 stainless switches see pages 3-4–3-6.)
