UMG 604
Direct measurement
Nominal currents up to 5 A can also be measured
directly with the UMG604. In this case it must
be noted that each current measurement input
may be loaded continuously with 6 A or for
1 second with max 100 A.
As the UMG604 does not have any integrated
protection for the current measurement, this
protection (e.g. 6A fuse type C) must be
provided for during installation.
