Technical   >   IP Ratings


The IP rating system provides a means of classifying the degrees of protection from dust, water and impact for electrical equipment and enclosures.  The system is recognised in most European countries.

 

The degrees of protection are most commonly expressed as “IP” followed by two numbers, where the numbers define the degree of protection.  The first digit indicates the extent to which the equipment is protected against particles, or to which persons are protected from enclosed hazards.  The second digit indicates the extent of protection against water.
 



DIGIT

FIRST NUMBER – SOLID

SECOND NUMBER – LIQUID

0

Not protected

Not protected

1

Protected against solid objects

over 50mm, e.g. accidental touch

by hand

Protected against vertically drops of

water

2

Protected against solid objects

over 12mm diameter, not

exceeding 80mm long, e.g.

fingers

Protected against direct sprays of

water up to 15° from the vertical

3

Protected against solid objects over

2.5 mm, e.g. tools and wires

Protected against sprayed water

Up to 60° from the vertical

4

Protected against solid objects over

1.0mm, e.g. small wires

Protected when sprayed from any

direction – limited ingress

allowed

5

Protected against dust, limited

Ingress (no harmful deposit)

Protected against low pressure

jets, from all directions – limited

ingress allowed

6

Dust tight – totally protected

Against dust

Protected against strong jets of

water with limited ingress allowed

7

n/a

Protected against temporary

immersion between 15cm an 1 m for

up to 30 minutes

8

n/a
