Exceptional occurrence of overvoltage External design Standard reference chapter 3.3 to IEC 61 439-1 Extensive testing of the Ri4Power system always applied to a single enclosure or a multiple enclosure design.

This value IK10 has been verified, and therefore all lower IK protection defines the enclosure cover’s resistance to mechanical categories IK00 – IK09 are likewise covered. damage.
