manual opening and closing of an energized recloser. Pulling down the handle trips and locks open the main contacts of the recloser. Lifting up the handle closes the closing-coil contactor and, if the closing circuit is energized, the closing coil will close the main contacts. The handle can be operated with a hookstick. This handle is trip-free.
