Eaton's NOVA NX-T recloser is built for a smarter grid

Built on decades of industry leadership in recloser technology, Eaton's Cooper Power series NOVA NX-T recloser delivers enhanced sensing performance, proven reliability  and simplified configuration and use.

Enhance sensing performance

Eaton's Cooper Power series NOVA NX-T recloser is a fully integrated solution with highly accurate, resistive source-side and optional loadside sensors, achieving ±2% accuracy across the full rated temperature range

Easy-to-use twist-lock cable connector

Eaton's Cooper Power series NOVA NX-T recloser protects all sensitive control electronics in an IP43-rated enclosure. MIL-SPEC twist/lock connectors positively seal out moisture, and Eaton’s proven epoxy insulation solution withstands extreme environmental temperature ranges.

Simplify configuration and use

From standard site-ready designs to large reflective 360-degree-viewable position indicators, every aspect of the NOVA NX-T recloser is designed for ease of configuration, installation, operation and control.

Site-ready design reduces installation time and cost

Eaton’s Cooper Power series NOVA NX-T recloser is available in a site-ready design from the factory to reduce installation time and cost for pole installations. Site-ready accessories that can be pre-mounted and pre-wired include arresters, PTs and load-side voltage sensors. A variety of configurations are available to meet evolving installation requirements.
