Ingress Protection (IP) and what it means
IP code (or international protection level, sometimes also interpreted as intrusion protection class *) contains the letter IP followed by two digits and optional letters. As defined in the International Standard IEC 60529, it classifies the degree of protection of the protective device into solid objects (including body parts such as fingers and fingers), dust, accidental contact and water intrusion in electrical enclosures. The standard is intended to provide users with more detailed information than fuzzy marketing terms (such as waterproofing).
The number (characteristic number) indicates that the conditions summarized in the table below are summarized. For example, a power outlet with a protection class IP22 prevents finger insertion and is not damaged or becomes insecure in specific tests exposed to vertical or nearly vertical dripping. IP22 or 2X is a typical minimum requirement for indoor electrical accessories design.
*Explanation of the letters IP is given in IEC 60529 (Ed. 2.1), clause 4.1
First Digit: Solids
The first digit indicates the degree of protection provided by the enclosure against dangerous components (such as electrical conductors, moving parts) and solid foreign matter entry.
Second Digit: Liquids
Protection of the equipment inside the enclosure against harmful ingress of water.
