Introduction to the Protection Level of Industrial Switches

The IP rating (Ingress Protection rating) is a crucial standard used to define the level of protection provided by enclosures for electronic devices, including industrial switches. The protection level (IP level) of industrial switches is an important indicator used to measure their dust-proof, waterproof and other protective capabilities. This rating specifies the degree to which the switch is protected against solid particles (like dust) and liquids. The IEC (International Electrotechnical Commission) 60529 Standards document specifies an international classification system for the sealing effectiveness of enclosures of electrical equipment against the “intrusion into the equipment of foreign bodies and moisture. The code follows the scheme: 1. Digit:. IP stands for “International Protection” Rating or “Ingress Protection” Rating. It's a standard defined by the IEC.
