The Schneider Electric LT6CT1001 is a 100/1 current transformer for the TeSys T (LT6) motor management relay, giving class 5P accuracy at a precision limit factor of 15 so the relay reads motor current without passing full load current through its own terminals.
Match this 100/1 ratio to the motor's full-load current so the TeSys LT6 relay's current input stays within its working range; a lower-ratio transformer on a higher-current motor saturates the core and gives an inaccurate reading, while an oversized ratio loses resolution at low load. The class 5P / PLF 15 accuracy is adequate for protection metering on the LT6 relay but is not a revenue-metering transformer.
