IP ratings define an electrical enclosure’s level of protection against ingress of water and solid objects based on the enclosure’s ability to pass performance criteria outlined by the international standard IEC 60529. The rating consists of the letters IP followed by two digits, e.g. IP54. The first digit indicates the level of protection against solid objects. The second digit indicates the level of protection against liquids. To help you understand what kind of protection each IP rating offers, we’ve created this guide for your reference.
