Viper®-ST Recloser

Viper®-ST independent pole operated recloser combines the time proven reliability of electronically controlled, vacuum fault interrupters with the maintenance-free benefits of a solid dielectric insulated device. The recloser offers ultimate user flexibility by permitting three distinct mechanical operation modes, either 1-phase trip / 1-phase lockout, 1-phase trip / 3-phase lockout, or 3-phase trip / 3-phase lockout. Designed with up to 6 internal voltage sensors, 3 dual-ratio current transformers for current sensing, and a magnetic actuator system that provides for local and remote operation. The Viper-ST recloser is automation-ready to simplify conversion for any future automation requirements. The recloser provides overcurrent protection for systems through 38kV maximum, up to 1000A continuous current, with 12.5kA symmetrical interrupting and 16kA symmetrical interrupting up to 27kV.  Vertical insulator L-shaped configurations and horizontal insulator Z-shaped configurations are available to increase installation flexibility. Also available in padmount.
