Display of 35 elec- trical measured values and con- sumption values in switchgear assem- blies, infeed or outgoing feeders. Up-to-date consumption data of the multimeter available worldwide over LAN data com- munication.
Measurement of consumption data and plant capacity utilization in three-phase systems of system components, offices or holiday apartments. Straight-through transformers for installation in distribution boards and non-contact measuring of primary currents. For switching over the phases for voltmeters and ammeters
