DRCA 1 CT 140

Product catalog summary

Overview: This document is a data sheet for the DRCA 1 CT 140 transducers, which are part of the DRCA 1 residual current analysis system by Doepke. These transducers are designed to measure and analyze residual currents in combination with the DRCA 1 detection unit.

Functionality: The transducers work with evaluation units to measure residual currents. They are specifically compatible with the DRCA 1 detection unit and cannot be used with other units. They have a wide detection frequency range from 10 Hz to 100 kHz.

Features: The transducers are available with different internal diameters to fit various cables. They feature a robust plastic housing and a reverse polarity protected connection socket for the measuring cable.

Mounting: The devices are mounted using supplied brackets and can be installed in any position on stable substrata.

Applications: These transformers are used in conjunction with the DRCA 1 analysis system for residual current detection.
