Enclosures

The degree of protection indicates the suitability of a motor for specific ambient conditions
with regard to humidity as well as the protection against contact and the ingress of foreign
particles. The degrees of protection are classified by EN 60529.
The first code number after the code letters IP indicates the protection against the ingress of
foreign particles and dust. The second code number refers to the protection against the
ingress of humidity.
Code number 1 Degree of protection
0 No protection
1 Protection against the ingress of foreign particles d >
50 mm. No protection in case of deliberate access.
2 Protection against medium-sized foreign particles,
d > 12 mm, keeping away fingers or the like.
3 Protection against small foreign particles d > 2.5 mm.
Keeping away tools, wires or the like.
4 Protection against granular foreign particles, d > 1 mm,
keeping away tools, wire or the like.
5 Protection against dust deposits (dust-protected),
complete protection against contact.
6 Protection against the ingress of dust (dust-proof),
complete protection against contact.
