Description
Special holders have been developed to enable monitoring of the cabinet system for arcing
faults. The VA1DA1 arc systems from Vamp Ldt. as well as TVOC from ABB are supported
by these holders.
Figure 8-30
If ARC detectors are to be used, factory-fitted holding plates are installed in the cabinet at
points defined during configuration.
The ARC processing units should preferably be centrally mounted. Line Connection Modules
or variable units are ideal for this.
