AF00-107
Notes: *1 Busbar mounting brackets are sold separately. When ordering, specify
the CT type number and rated primary current. If the rated primary
current is 1000 to 2000A, also specify the number of busbars required.
*2 Epoxy resin mold is used to isolate rated primary currents of 5000 or 6000A.

Primary current: 150 to 6000A
Secondary current: 5A
Description
CC3M CTs can be mounted vertically or
horizontally by changing the position of
the mounting base. Also, the busbar can
be mounted directly using a mounting
bracket as illustrated, so a busbar
mounting angle or holes are not
required.

Direct busbar mounting
CC3M2 CTs with a rated primary current of 150A or CC3M3 CTs
with a rated primary current of 200A, 250A or 4000 to 6000A
cannot be mounted directly to a busbar because the CT is too
heavy for the cross section of the busbar.

The busbar must be located in the center of the through hole of the
CT. Be sure that the busbar does not come into contact with the wall
of the through hole.
