OROIDAL CURRENT TRANSDUCER SERIES
MU 1142 REV.2
Description
The current transducers series FL, used with Dossena fault
locators, allow to detect the very low currents that are used for
fault location in IT industrial network. Transducers must be
installed upstream of the line or load to be monitored.
Direction for installation:
- The toroidal current transducer connections require 6.3mm
female standard faston.
- Push the transducer to fix it on the DIN rail; to remove it, use a
screw-driver, as shown in the picture.
- Cables inside the transducer must be centred and tightened
together.
- Do not bend cables/bars near transducer.
- The CT internal diameter must be two times the cable harness
diameter.
- For the right installation use terminals 1-2 of the transducer (do
not connect terminals 3-4)
