Ingress Protection


IP (Ingress Protection) Code Symbols

The chart below illustrates the use of special symbols in the IP classification system. In the "1st digit" columns, note the grid-like symbols next to numbers 5 and 6. In the "2nd digit" columns numbers 3–8 are symbolized by teardrop shaped symbols, sometimes enclosed in a box or a triangle, sometimes unenclosed (7–8). These symbols can be placed on equipment to illustrate the IP protection provided.
