Viper®-S Solid Dielectric Three Phase Recloser

The Viper-S solid dielectric, three phase recloser combines the time proven reliability of electronically controlled-vacuum fault interrupters with the maintenance benefits of a solid dielectric insulated device. Designed with a mechanically ganged operator for three-phase automatic or manual trip operation providing overcurrent protection for systems rated up to 38kV maximum, 800A continuous current, and 12.5kA rms symmetrical interrupting.

Features and Benefits

  • Reliable performance Reliable performance – Viper-S reclosers utilize G&W Electric’s time-proven epoxy polymer system to fully encapsulate the vacuum interrupters. This system provides excellent insulation properties while providing fully shielded, void-free construction.

  • Ease of Installation The Viper-S is lightweight and compact. Site-ready designs provide all accessories including bracket, arresters and voltage transformers preassembled prior to shipment significantly reducing installation time.

  • Manual Trip and Lockout Operation For manual open and lockout operation, a handle is provided permitting hook stick operation. Pulling the handle down trips and locks out the recloser.

  • Control Flexibility Viper-S three-phase reclosers are designed to work directly with the SEL-351R control along with a variety of control options upon request.

  • Power Grid Automation Ready The Viper-S is automation-ready, simplifying conversion for any future automation requirements. Options for adding multi-ratio current transformer for additional applications.
