What is an IP Rating?


An IP rating (International Protection Rating or Ingress Protection Rating) is used to classify how effective an electrical enclosure is at protecting against the entry of solid objects and liquids. Developed by the IEC (International Electrotechnical Commission), an IP rating consists of two numbers: the first number rates the protection against solid objects from 0 to 6 and the second number rates the protection against liquids from 0 to 8.


1st Digit

0 – No protection

1 – Protected against solid objects larger than 50 mm (for example, hands)

2 – Protected against solid objects larger than 12.5mm (fingers)

3 - Protected against solid objects larger than 2.5 mm (tools and wires)

4 – Protected against solid objects larger than 1.0 mm (wires and nails)

5 – Dust protected (protected against entry of enough dust to cause damage)

6 – Dust tight (no entry of dust at all)


2nd Digit

0 – No protection

1 – Protected from water drops

2 – Protected from water drops at a 15 degree angle

3 – Protected from water drops at 60 degree angle

4 – Protected from water splashing from any angle

5 – Protected from low pressure water jets from any angle

6 – Protected from strong pressure water jets from any angle and heavy seas (for example, on a ship deck)

7 – Protected during temporary submersion in water (30 minutes at 3 feet)

8 – Waterproof (protected during permanent submersion, up to 13 feet)


An IP65 rating means that the component is dust tight and water resistant against low pressure water jets from any angle.
