ABB Unigear ZS1 Replacing CT's

[Gaiser]

Hi,

Does anyone has experience with replacing CT's on ABB Unigear ZS1 panels?
Panels are almost mounted to a wall, so there is no space in the back.
The only possibility is to dismantle a part of the cabinet to remove it.
Some tips would be appreciated. As it is not quite simple to do this job from the cable compartment..

Some informormation:
- 1 cable 3x50mm² inside
- no VT
- 3 CT's


It is quite the same as with a Siemens NXAIR
Thanks in advance!

That is a quite interesting tool to help installing the CT's. It is possible to open the base plate/cover. There is also a cable basement underneath so i think we can make it up there when standing in our supports.
I will have to look when i can open a spare cabinet.
