Product FAQs
8 answersCan the EHD3020L replace older Westinghouse EHD breakers?
Yes. Eaton acquired the Westinghouse distribution and control business. The Series C EHD3020L is the direct, manufacturer-supported replacement for legacy Westinghouse and Cutler-Hammer EHD breakers with the same specifications.
What does the L suffix indicate on the EHD3020L catalog number?
The L suffix indicates that the circuit breaker comes factory-equipped with standard pressure steel lug terminals on both the line and load sides.
Can I install this F-Frame breaker in older motor control center buckets?
Yes, the EHD3020L fits standard F-Frame footprints. However, when retrofitting into older legacy motor control center buckets, you may need to update the handle mechanisms to accommodate the modern Series C design.
Can the EHD3020L be used in reverse feed applications?
Yes. Eaton F-Frame circuit breakers, including the EHD3020L, are suitable for reverse feed use.
Which specific panelboards are compatible with the EHD3020L?
This breaker is designed for Eaton Series C panelboards, and it specifically fits inside Eaton and Cutler-Hammer Type PRL3 and PRL4 panels when using the accurate mounting hardware.
Can I modify the trip curve or adjust the settings on this breaker?
No. The EHD3020L features a non-interchangeable trip unit with fixed thermal and fixed magnetic settings. The long-time and instantaneous protection levels are factory set and cannot be modified for custom curve shaping.
Is the EHD3020L HACR rated for HVAC applications?
Yes. All Eaton Series C F-Frame circuit breakers are HACR rated, making this breaker suitable for heating, air conditioning, and refrigeration motor group applications.
Can this breaker be used for high intensity discharge lighting?
Yes. Eaton F-Frame circuit breakers rated between 10 and 30 amps, including this 20-amp model, are suitable for High Intensity Discharge (HID) lighting use.
