suitable for making arc proof switchgear.
• The reinforced enclosure alone cannot
guarantee arc proofing of the switchgear
designed by the customer. To guarantee
this, some representative configurations,
selected by the customer, must be
subjected to the tests according to the
prescriptions indicated in the IEC 62271-
200 Standards.
• For UniGear ZS1 type switchgear, all the
door knurls must be tightened to guarantee
arc proofing.
