IK impact resistance level
The impact resistance level degree of
protection measure the resistance of
enclosures for electrical control gear against
mechanical stress. One can expect the follow-
ing maximum loads practice:
–
up IK05: blows with the hand fist
–
IK06: blows with 500 hammer
from distance cm
–
IK07: blows with 500 hammer

IK02 0.70
IK06 1.0
This provides information about the impact
energy, which enclosure can withstand
without breaking. The international standard
IEC 62262 (corresponds 62262) lists
