D, DV single-phase reclosers

Discontinued

Reclosers

Eaton's Cooper Power series D and DV hydraulically controlled automatic circuit reclosers provide reliable, economical overcurrent protection for distribution systems. Additionally, the reclosers use oil as the arc-interrupting medium and provide single-phase load protection, tripping and automatic clearing of temporary faults.

Provides single-phase load protection, tripping and automatic clearing of temporary faults
Features a compact and self-contained operation design
Coordinates with circuit breakers, sectionalizers, fuses and other reclosers in the distribution system
Supplies the energy for contact closing and stores energy in the trip mechanism with its closing solenoid
Uses oil as the arc-interrupting medium

Ready for use on heavily loaded circuits

Eaton's Cooper Power series D and DV reclosers sectionalize single-phase branches of three-phase feeders. The high continuous current and interrupting capacity of the D and DV reclosers enables them to be used on heavily loaded circuits with high available fault currents.

High-voltage solenoid recloser closing

Tripping is initiated by a series-trip coil that releases the stored-energy trip mechanism when an overcurrent occurs. Current-carrying and interrupting capacities depend on the current rating of the series trip coil. A closing solenoid supplies the energy for contact closing and also stores energy in the trip mechanism.
