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.

Accessories

High Accuracy Sensors – Accusense Voltage Sensors

Controls – The Viper-S works directly with a variety of popular controls.

SEL-351R Recloser control

Control Connections – The traditional 14-pin recloser control connector design is the same as other Cooper reclosers permitting easy change out of previously installed controls and/or reclosers.

SEL-651RA

The SEL-651RA is a direct replacement of the SEL-351R with a 14 pin interface and offers exceptional protection and communications capabilities for Automatic Network Reconfiguration and other distribution automation needs. These capabilities help you maintain reliable service to as many customers as possible in the event of a fault.

Features:

  • Six voltage inputs support measurements on both sides of the recloser for advanced distribution automation and monitoring
  • Comprehensive communications protocols and interfaces ease integration into distribution automation systems
