Eaton Bussmann H79-3 NFPA Through-The-Door Handle Kit

Eaton Bussmann H79-3 NFPA Through-The-Door Handle Kit is a red, padlockable exterior handle accessory for RDF40 A0J rotary disconnect switches, built to support NFPA-79 through-the-door operation. As part of the H79 NFPA handle family, the kit enables operate-from-outside control of the RDF40 A0J without opening the enclosure door, supporting lockout/tagout procedures and enhanced safety in industrial switchgear. The assembly is designed for reliable, visible identification in control rooms and manufacturing environments, with a high-contrast red finish and a padlock-ready design that allows securing the handle in the desired position during maintenance. Typical applications include motor control panels and other electrical switchgear where external, door-closed operation is required by NFPA-79, providing a straightforward retrofit for compatible RDF40 series disconnects.
