20 AMP 480V 3 POLE 3 PH

MODEL EHD3020L

The EHD3020L is a specific 20 Amp, 3 Pole, 3 Phase molded case circuit breaker manufactured by Eaton Cutler-Hammer (Series C, F-Frame lineup), which features standard line and load terminal lugs for standalone panel/enclosure mounting.

When combined with an Appleton explosion-proof enclosure, this breaker serves as the core internal mechanism for hazardous-location overcurrent and short-circuit protection. While the EHD breaker frame itself is technically rated for a maximum of 480V AC (with a 14 kAIC interrupting capacity at 480V), the surrounding Appleton heavy-duty explosion-proof enclosure assemblies or receptacle
