E, 4E, V4E, H, 4H, V4H, L, and V4L
Eaton's Cooper Power series Kyle Types E, 4E, V4E, H, 4H, V4H, L, and V4L single-phase, hydraulically controlled reclosers provide reliable, self-contained distribution-circuit overcurrent protection at low initial cost, and require minimal service.
Tripping is initiated by a series-connected coil. Current-carrying and interrupting capacities vary with the operating coil's rating, which is selected to meet circuit requirements. A choice of dual time-current characteristics permits coordination with other protective devices.
A non-reclosing feature (standard on all Eaton Cooper Power series Kyle reclosers) is set with a hookstick-operated lever for one operation-to-lockout without removing the recloser from service.
|Ratings||Single-phase Types H & L reclosers are for 14.4-kV three-phase systems|
|Ratings||Types E, 4E, and V4E reclosers are designed for 24.9 kV three-phase systems.|
Two types of interrupters are available:
- Types E, 4E, 4H, and L reclosers: Current interruption takes place in oil.
- Types V4H, V4L, and V4E reclosers: Equipped with vacuum interrupters.
Single- phase H-group and L-group reclosers are designed, tested, and rated for operation on 14.4-kV three-phase systems.
Types E, 4E, and V4E reclosers are designed for 24.9 kV three-phase systems.
Types E, 4E, and V4E reclosers can also be used for operation on single-phase taps of a 20/34.5-kV system where the 150-kV BIL rating is satisfactory. The bushings and other line-to-ground insulation are adequate for the 20 kV line-to-ground voltage stress. Since the interrupting capability is 24.9 kV, application on this system is limited to single-phase taps only.
