Product FAQs
6 answersWhat is the modern replacement for the legacy HFA3030 circuit breaker?
The HFA3030 is a legacy H-Frame component. For modern system upgrades, it is commonly replaced by the Eaton HFD3030, which provides equivalent 30A thermal magnetic protection for Series C panels.
Is the HFA3030 the same as the Cutler-Hammer or Westinghouse version?
Yes, the HFA3030 has been manufactured under the Westinghouse, Cutler-Hammer, and Eaton brands over its lifecycle. They share the same physical dimensions, mounting style, and electrical ratings.
Can I install the HFA3030 in a standard residential load center?
No, the HFA3030 is a commercial molded case circuit breaker designed specifically for Eaton Series C panelboards, switchboards, and motor control centers. It will not fit in standard residential load centers.
Can I adjust the trip curve on the HFA3030?
No, this breaker features a fixed thermal and fixed magnetic trip unit. It provides standard long-time and instantaneous (LI) protection, but the trip thresholds cannot be adjusted in the field.
Does the HFA3030 plug into the panelboard?
No, this is a bolt-on circuit breaker. It requires a bolted connection directly to the panelboard busbar, which provides a more secure mechanical and electrical connection than plug-on types.
Do I need to purchase lugs separately for the HFA3030?
The breaker typically includes standard load-side lugs that accept wire gauges from 14 AWG up to 1/0 AWG. Always verify terminal torque specifications during installation.
