    Hi,

    I have been looking through some current sensor datasheets and notice that some of the current ratings are specified in "A.t"

    What does this mean?

    Thanks,
    Dan

    I'd guess they are the ones that you thread a cable through?

    The rating is probably amprere-turns.

    eg. if the sensor full scale is 50AT, then a single pass of wire through it would read to 50A or five passes of the wire through it would read full scale at 10A.

    They are the feed through kind.
    That makes sense.
    Thanks.
