difference between a four point starter and three point
starter
Answer Posted / k.sathish kumar
In three point starter NVR (no voltage relay)is series with
shunt if voltage falls certain value NVR De energized due to
insufficient magnetic field and motor turned off. But in
four point starter NVR energized directly from DC supply
thus the draw back of 3 point starter rectified
