Remarks:
(1)Integrated current transformer is used for integrated protector with current specification of
100A and below
;
The split current transformer is used for the current specification of 100A and
below;
250A and 800A current specifications use another type of split current transformer. For the
external dimensions of the transformer, please refer to the "external dimensions and installation".
(2)The temperature measurement support sensor type is PTC or NTC or PT100.
