Current Ratings of CTs Available from DENT Instruments
All of the CTs in the table are available from DENT Instruments.
These are internally shunted CTs (333.3 mV output) which
make them safe to handle even when connected to an
energized wire. They are also case-insulated for 600V phase-to-
phase service. Do not use on services with higher voltages.
The following table is a list of the UL recognized (61010-1) CTs
