Protection types
Information on IP protection (IP code) can be found in DIN EN 60529:2000-09 (VDE 0470 part 1).
Plugs and sockets used to be classified according to the degree of protection against the entry of moisture:
splashproof | = drop in a triangle |
| ||
watertight | = 2 drops |
|
Today, complete IP protection according to IEC 60529, EN 60529 is specified for plugs and sockets, as they are tested in line with this standard.
IP 44 | = Protection from solid bodies with a diameter ≥ 1 mm, splashproof | ||
IP 67 | = Protection from dust ingress, protection against immersion |
Having been properly installed, sockets and connectors must provide the degree of protection defined by the rating, whether the plug is inserted or not. The protection type for plugs and inlets only applies if they are in contact with the matching piece of the connector or with a fixed cover, if applicable.
Plugs and sockets must be IP 44 or IP 67. Plugs and sockets with rated currents of 100/125A must be IP 67. 100/125A sockets that are fastened to an enclosure or form a structural unit with the enclosure can be IP 44. For sockets IP 67, a bayonet system has been adopted as the standard in order to simplify their use especially under rough working conditions.
IP 44 or IP 67 is indicated on the appliances.
