Eaton's Cooper Power series NOVA NX-T recloser builds on the proven solid epoxy and vacuum interrupter technology of the NOVA recloser platform by incorporating a robust and reliable actuator design with integrated load-side resistive voltage sensors. In addition, the weather-resistant cable connector system helps protect cables from harsh weather conditions.
Eaton's pad-mounted electronically controlled, enclosed NOVA recloser features solid-dielectric vacuum interruption in a mild steel enclosure design, safeguarding against weather, tampering and rodents.
