V4H, V4E, V4L single-phase reclosers

Overview

Eaton's Cooper Power series V4H, V4E and V4L are single-phase, hydraulically controlled reclosers that provide self-contained overcurrent protection and use vacuum as the arc-interrupting medium. They are offered at low initial cost, require minimal service, and provide a minimum 15 year routine maintenance. No external power or battery source is required and the design includes an enhanced-safety grounded tank. They offer a choice of dual time-current characteristics to simplify coordination with other protective devices. - Rated system nominal voltage (kV): V4H: 2.4–14.4; V4L: 2.4–14.4; V4E: 24.9 - Rated system maximum voltage (kV): V4H: 15.5; V4L: 15.5; V4E: 27 - Maximum continuous current (amps): V4H: 200; V4L: 280; V4E: 280 - Maximum interrupting current (symmetrical amps) @2.4–4.8 kV: V4H: 3000; V4L: 6000; V4E: – - Maximum interrupting current (symmetrical amps) @4.8–8.32 kV: V4H: 2500; V4L: 6000; V4E: – - Maximum interrupting current (symmetrical amps) @8.32–14.4 kV: V4H: 2000; V4L: 6000; V4E: – - Maximum interrupting current (symmetrical amps) @24.9: V4H: –; V4L: –; V4E: 4000 - Rated system withstand voltage (BIL) (kV): V4H: 110; V4L: 110; V4E: 150 - 60 Hz insulation level withstand rating Dry 1-Min.

The V4H, V4E and V4L reclosers provide reliable, self-contained overcurrent protection and help prevent permanent outages, which the product states improves customer service and reduces operating costs. Their hydraulic control and requirement of no external power or battery source simplify operation and reduce installation and operating costs. The reclosers offer a choice of dual time-current characteristics to simplify coordination with other protective devices, with current-carrying and interrupting capacities that vary with the operating coil’s rating selected to meet circuit requirements.
