Installation of the current
transformer
Additional informations
Our circuit breakers have trip units with a
built-in ammeter
(see Micrologic
catalogue).
Their use eliminates the need for installing a CT on the busbars.
The CT casing
is a solution for installation of CTs up to 1600 A.
CTs can be installed in the casing (cat. no. 03506).
It is equipped with a frame made up of 2 uprights, adjustable in depth and 2 slotted
cross-members to fix the cables, install CTs or install a busbar support with 75 mm
spacing.
It is secured in the switchgear compartment of a 400 or 600 mm deep cubicle.
The 300 mm duct
allows easier mounting of CTs.
To install 2 CTs, downstream from a circuit-breaker for example, it is often easier to
use a 300 mm wide duct (cat. no. 08403 for 400 mm depth or cat. no. 08603 for
600 mm depth).
