Important note

Product information
The ACT20C-CMT-XX-AO-RC-S current measuring transducers from the ACT20C series measure and monitor DC and AC currents of up to 60 A. The True RMS method used allows for precise measurement, even in case of distorted current waveforms. The devices feature integrated limit value monitoring with an adjustable switching threshold, delay and hysteresis, as well as a relay output.

Properties
  • True RMS value measurement or arithmetic averaging (AA) measurement and contactless through-hole technology
  • Limit value monitoring for overcurrent or undercurrent
  • Relay output by means of the open-circuit / closed-circuit principle
  • Infinitely variable trigger delay
  • Operational status and error display on a front panel LED and output signalling according to NE43, NE44, NE107
  • Galvanic four-way insulation for secure isolation according to IEC/EN 61010-2-201:2013
