V4H, V4E, V4L single-phase reclosers
Eaton's Cooper Power series V4H, V4E and V4L single-phase, hydraulically controlled reclosers provide reliable, self-contained overcurrent protection. Additionally, they’re offered at low initial cost and require minimal service.
Economic V4H and V4L reclosers are rated for operation on 14.4-kV three-phase systems
Premium V4E reclosers rated for operation on 24.9 kV three-phase systems
Provides reliable, self-contained overcurrent protection at a low initial cost
Improves customer service and reduces operating costs as they help prevent permanent outages
Uses vacuum as the arc-interrupting medium
Simplified operation and reduced installation costs
Eaton's Cooper Power series types V4H, V4E and V4L single-phase reclosers are hydraulically controlled. No external power or battery source is required.
Simplified coordination with other protective devices
Eaton's Cooper Power series types V4H, V4E and V4L reclosers offer a choice of dual time-current characteristics. Current-carrying and interrupting capacities vary with the operating coil’s rating, which is selected to meet circuit requirements.
Eaton's Cooper Power series reclosers are designed and tested in accordance with the following ANSI standards: C37.60 and C37.85 and ANSI Guide C37.61

This brochure outlines Eaton’s Cooper Power series broad commercial and industrial medium-voltage transformer, switchgear, fuse, sectionalizer, switch, regulator, tool, OEM equipment, cable accessory, lightning arrester, power capacitor and recloser offerings.
This brochure discusses Eaton’s Cooper Power series single-phase V4H, V4L and V4E vacuum reclosers which are complete self-contained systems that don’t require external power sources, such as batteries or potential transformers (PTs) and provide full functionality and circuit overcurrent protection over the entire voltage and current operating range.
This catalog describes ratings and ordering information for Eaton’s Cooper Power series E, 4E, V4E, H, 4H, V4H, L and V4L single-phase and 6H and V6H three-phase reclosers which are hydraulically controlled and tripping is initiated by a series-connected coil.
This catalog describes the general ratings and ordering information for Eaton’s Cooper Power series reclosers which are self-contained devices with the necessary intelligence to sense overcurrents to time and interrupt fault currents and to re-energize the line by reclosing automatically.
This document provides installation instructions for KA705H4-1 and KA705H4-3 plunger and plunger stop kit for Eaton’s Cooper Power series 4H and V4H single-phase reclosers and 6H and V6H three-phase reclosers.
This document provides installation and adjustment instructions for adjustable control valves for the B, C and D time-current curves. The adjustable control valve can be used to replace the high pressure control valve in Eaton’s Cooper Power series H, 3H, 4H, V4H, 6H and V6H reclosers.
This document describes installation instructions for the adjustable control valve assembly for the B, C and D time-current curves on Eaton’s Cooper Power series L, E, 4E, V4L and V4E hydraulic reclosers.
This document describes periodic inspection, routine maintenance instructions, testing, component replacements, and adjustments for Eaton’s Cooper Power series V4L and V4E hydraulically controlled, single-phase, vacuum interrupting reclosers.
This document compares the ratings and standards of reclosers and breakers to aid in the evaluation and application of automatic circuit reclosers and high-voltage circuit breakers that provide alternate means for distribution circuit protection.
The purpose of this paper is to provide insight on condition-based monitoring techniques that can be applied to oil-insulated, vacuum interrupting single-phase reclosers by examining stresses that drive recloser wear-out and the design features that address those stresses.
