UE防爆压力开关选型J120-171（UE explosion-proof pressure switch selection J120-171 ）

Selection of UE explosion-proof pressure switch J120-171 J120-172 J120-173 J120-174 US UE authorized agent UE pressure switch The protection standard of US UE switch NEMA protection level is the shell protection standard of the American Electrical Manufacturers Association industrial control devices and systems . In addition to dustproof and waterproof, NEMA's protection standard also includes explosion-proof (IP code only includes dustproof and waterproof). NEMA 4X: (watertight, dusttight, corrosion-resistant, indoor or outdoor use enclosures): Intended for use indoors or outdoors, primarily to provide a degree of protection against corrosion, flying dust and rain, splashing water, hose-out water , and damage due to external icing. NEMA 4X is equivalent to IP66 What's the difference?
