Checks

After the above-mentioned operations, carry out the following 

checks:
–  check that the connections do not exert any force on the 

terminals 

–  check tightness of the connections.

5.6.2.   Withdrawable contactors and enclosures

The withdrawable contactors are used in the UniGear ZS1 
type switchgear and in the PowerCube modules.
Appropriately fixed together in the configurations defined 

by the customer, the enclosures build up medium voltage 

switchgear consisting of various units.

Rules for designing the switchgear

Arc proofing

The ABB enclosures are supplied with a reinforced door, 

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.
