Electrical Operation
The Type NOVA recloser utilizes an interface circuit located
in the mechanism housing. The electronic interface circuit
controls the opening and closing signals to the magnetic
actuator. Both control-powered and auxiliary-powered
interface options are available. Refer to Figures 26 and 27
for wiring diagrams.
OPEN/CLOSE Contact Position
