Current Transformers
Due to the Current ratings of this size of Soft Starters,
an “Interposing CT” is required. A small CT is fitted
internally to these units and an additional CT, rated for
the size of the Starter, is provided separately. This
MUST be fitted onto the conductors in the L3-T3 phase
and be connected to the marked terminal block under
the front cover.
