Renewal Parts
DC Operation
These DC coils have separate
pick-up and seal windings.
The pick-up winding must be
connected to an early break
normally closed auxiliary
contact block and provide
the magnetic force required
to close the magnet. As the
magnet approaches the
closed position, the early
break normally closed contact
is opened and the holding coil
is inserted in series with the
pick-up winding.
The early break contact
block (C320KGD1) has to
be attached to the side of
the contactor, taking up one
of the positions available
for add-on auxiliary contact
blocks.
