This new advanced design is to replace the CT-116 and CT-117
designs as the CT-620 allows for both a horizontal or a
90° primary connection.
The base mounting centres are
interchangeable with the previous designs although the primary
connections are not.
The primary connections are
by means of a single bolt up to 400A and two bolts are used
Base mounting is by four tapped
inserts moulded into the resin.
