IP Ratings

The IP rating system provides a means of classifying the degrees of protection from dust, water and impact afforded by electrical equipment and enclosures. Details of a third IP numeral are also shown, this figure is used in corresponding international standards to indicate degrees of resistances to impact.

 

 

IP

FIRST NUMBER
Protection Against Solid Objects

0


No Protection

1


Protected against solid objects over 50 mm, eg. accidental toach by hands.

2


Protected against solid objects over 12 mm, eg fingers

3


Protected against solid objects over 2.5 mm (tools, wires)

4


Protected against solid objects over 1 mm (tools, wires, small wires)

5


Protected against dust - limited ingress (no harmful deposit)

6


Totally protected against dust

IP

SECOND NUMBER
Protection Against Liquids

0


No Protection

1


Protected against vertically falling drops of water

2


Protected against direct sprays of water up to 15° from vertical

3


Protected against sprays to 60° from vertical

4



Protected against water sprayed from all directions - limited ingress permitted

5



Protected against low pressure jets of water from all directions - limited ingress permitted

6


Protected against strong jets of water, e.g for use on ship decks limited ingress permitted

7



Protected against the effects of immersion between 15cm and 1m

8



Protected against long periods of immersion under pressure

IP
