Viper-SP Single-Phase Recloser
The G&W Electric Viper-SP is a 15.5–38 kV single-phase solid dielectric recloser for overcurrent protection on single-phase distribution, rural feeders and laterals, sold and supported in Texas and Oklahoma by Ryan Sales.
- 15.5-38kV
- 630-800A continuous
- 12.5kA sym interrupting
- 32.5kA peak withstand
- 10000 operations
Overview
The Viper-SP brings the Viper family's vacuum interrupter and solid dielectric technology to single-phase circuits through 38kV. It supports dead-line operation with battery-backed magnetic actuation, dead-front modules for lineman and wildlife safety, and dual-ratio CTs with 1% accuracy. Pole-mount L and Z configurations plus padmount options pair with the SEL-351RS Kestrel control for automatic single-phase reclosing.
