Eaton / Cutler-Hammer EHD1020L Molded Case Circuit Breaker

The "L" suffix indicates that the circuit breaker is supplied with factory-installed line and load side lug terminals. Models without this suffix typically ship as a frame only, requiring separate terminal purchases.

The EHD1020L fits Eaton Series C enclosures, switchboards, and panelboards designed for F-Frame molded case circuit breakers. It shares the same physical footprint and mounting hardware as other 1-pole F-Frame models.

Yes, the EHD1020L can substitute for FDB1020L and FD1020L components in many applications. Because all Series C F-Frame breakers share identical dimensions, they are physically interchangeable, but you must verify that the 14kAIC at 277VAC rating meets your specific fault current requirements.

Yes, Eaton F-Frame breakers in the 10A to 30A range, including the EHD1020L, carry SWD (Switching Duty) and HID (High Intensity Discharge) ratings. This makes them approved for switching fluorescent and HID lighting loads.

Yes, Eaton Series C F-Frame thermal-magnetic circuit breakers do not have line and load restrictions and are suitable for reverse feed applications.

The LI designation means the breaker includes fixed Long-Time (thermal) protection for overloads and fixed Instantaneous (magnetic) protection for short circuits. The trip unit is non-interchangeable.

The included line and load lugs accept wire sizes ranging from 14 AWG to 1/0 AWG. Always torque terminals to the manufacturer specifications printed on the breaker label.

Yes, the Eaton Series C platform uses standardized accessories. Shunt trips, auxiliary switches, and undervoltage releases designed for F-Frame breakers are fully compatible with the EHD1020L, as well as FD, FDB, and HFD models.
