Salient features:
The NOVAi recloser is a 3-phase, vacuum cut-out chamber, which is a successful combination of four advanced technologies: cycloaliphatic-epoxy solid-insulated encapsulation, high-performance vacuum cut-out chamber, low-energy operating mechanism reliable and an Eaton's Cooper Power Systems automatic microprocessor controller. Polymer solid insulators are highly resistant to ozone, moisture, pollution, UV, and trace.
