Fault Interrupting through 38kV, 800A, 12.5kA symmetrical interrupting. G& W' s 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. The reclosers are designed for three phase automatic or manual trip operation providing overcurrent protection for systems rated up to 38kV maximum, 800A continuous, and 12.5kA rms symmetrical interrupting.
