DC Operation
These DC coils have separate pick-up
and seal windings. The pick-up wind-
ing must be connected to an early
break normally closed auxiliary con-
tact block and provides 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 hold-
ing coil is inserted in series with the
pick-up winding.
