Description
Part of the legacy NEF series, the Eaton D50373-3 serves as a 100A non-automatic molded case switch for commercial and industrial applications. It provides manual switching and circuit isolation rather than overcurrent protection. This 3-pole, bolt-on disconnect mounts into Challenger, Westinghouse, and Eaton Pow-R-Line C panelboards. It serves as an exact drop-in replacement for discontinued systems, requiring no adapters to install.Specifications

Superbreakers did a great job for us. We called and asked if the breakers were actually in their possession. Withing 30 minutes they called us back (which is rare these days), and we got our breakers the next morning.
