IP Rating
IP (“Ingress Protection”) ratings are defined in international standard EN 60529 and rate the degree of protection provided by electrical enclosures against intrusion from solids and liquids (objects, particles, dust, water, etc.).
The higher the value of each digit, the greater the protection.
