Overview
These devices for measuring voltages and currents can be used
for monitoring input and output currents or device currents in
electric plants. They are suitable for direct connection in a
single-phase system or for three-phase systems when used in
conjunction with a measuring selector switch.
■
Benefits
•
The 7KT1 020 ammeters can be equipped with changeable
scales for primary currents of 60, 150 or 400 A AC, depending
on the transformer ratio of the installed current transformer.
The changeable scales are included in delivery. This ensures
universal application
•
Permanent overload up to 20 % does not damage the device.
Protection for your plant.
