IP Rating

The IP Rating refers to the Ingress Protection Rating. This is the level of protection that classifies and rates the degree of protection provided against intrusion of dust, accidental contact, and water by mechanical casings and electrical enclosures. The first digit of the IP Rating indicates the degree that persons are protected against contact with moving parts (other than smooth rotating shafts, etc.) and the degree that equipment is protected against solid foreign bodies intruding into an enclosure. The second digit indicates the degree of protection of the equipment inside the enclosure against the harmful entry of various forms of moisture (e.g. dripping, spraying, submersion, etc.).
