ACT20P – Current measuring transducer
Simple and quick configuration
DIP switches and potentiometers are located
on the front, which means they’re quickly
accessible even when installed.
Precise measured values
The real-value effective procedure allows you
to record the connected load’s real power
consumption, so you can reliably identify when
levels exceed or fall below the nominal current.

Easy to install
The asymmetrical cable bushing makes it
easier to feed through the power cable and
permits precise measurement on an extremely
small space.
22.5 mm
High process reliability
Reliable function thanks to a galvanic four-way
isolation and an impulse withstand voltage of
6.4 kV according to IEC 61010-2-201
