IP PROTECTION CLASSES

■

Protection against contact and foreign bodies according to IEC60529

■

Protection against water according to IEC60529

Evaluation of classification:

■

The test results according to the standard do not entirely exclude leaks and an individual test is therefore recommended

in critical cases (with the actual equipment layout)

■

The protection class for cabinets and enclosures is specified by IP (International protection) and two indices

Example IP55

Protection against penetration by water jets from all directions

Complete protection against contact with internal parts and against dust deposition

First index
