The cause of phase-off operation is that
in addition to the blown fuse , it may also be caused by the burnt contacts of the starter (such as contactor,
compensation starter ). This protection circuit
can protect the phase failure caused by the latter reason . In the figure
, relay KAI has three windings wound on an iron core; K&
is an auxiliary relay, whose function is to cut off the protection circuit when the contactor is released
. This circuit uses JCDJ type protective relay .
