Eaton's Cooper Power series NOVA recloser is a three-phase, vacuum-interrupting recloser that successfully combines four patented technologies: cycloaliphatic-epoxy encapsulation, high-performance vacuum interrupter, dependable lower power mechanism and an automated microprocessor recloser control. The solid polymer insulation is highly resistant to ozone, moisture, contamination, ultra-violet light and tracking. The axial-magnetic contacts are ideal for encapsulation and the dual-coil actuator provides for years of rugged performance.
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.
