Page 7: Recloser Operation
Types H, 4H, and V4H maintenance instructions Recloser operation Toggle assembly Electrical operation of the recloser is initiated by the trip solenoid. The trip-solenoid coil is connected in series with the distribution circuit and protected from transient surges by a bypass gap. When the current through the coil approaches twice the continuous current rating of the coil, the increased magnetic field pulls the solenoid plunger down into the coil. -
