Eaton DG322NRB Safety Switch

The Eaton DG322NRB is a fusible general-duty safety switch rated 60 amps at 240 volts AC three-phase. It houses Class H fuses and a neutral in a NEMA 3R metallic enclosure made of galvanised steel. The unit carries a 15 horsepower rating at 240 volts and is UL listed to UL98 and NEMA KS-1 standards.

Replacing open knife switches

This switch replaces non-fusible disconnects or open knife switches where overcurrent protection and a weather-resistant enclosure are required. The step up is justified when a 60 amp fusible device with a neutral and an IP14-rated NEMA 3R housing is specified for outdoor or damp locations. It covers 30 to 100 amp double padlocking and additional door locking capability.

Integrating into a three-phase panel

The enclosure measures 10.9 inches high, 8.7 inches wide and 7.4 inches deep with four wiring terminals for three poles plus neutral. Metallic construction provides grounding continuity while the NEMA 3R rating sheds rain and sleet. Installers must supply Class H fuses and size conductors for the 60 amp rating; the switch frees the panel from separate fuse blocks and exposed blades.

Questions about this item

What size enclosure opening does the 10.9 in tall galvanized steel box need for surface mounting?

The NEMA 3R metallic enclosure measures 10.9 in high, 8.7 in wide and 7.4 in deep, so allow that footprint plus clearance for the cover swing and conduit entries.

Which torque value should I apply to the four wire terminals when landing conductors?

The fusible switch accepts four wires on its 3PST contacts; follow the lug markings on the device for the correct tightening torque rather than guessing.

When do the Class H fuses and neutral assembly need replacement?

Replace the Class H fuses after any over-current event or when the switch reaches 60 A continuous load limits, and inspect the neutral block during each preventive maintenance cycle.
