Product FAQs
6 answersWhat is the modern replacement for the legacy HFA3035?
The Eaton HFD3035 is the designated modern substitute for servicing older installations that originally required the HFA3035.
Will this breaker fit in older Westinghouse or Cutler-Hammer panels?
Yes. Eaton acquired the Cutler-Hammer and Westinghouse distribution equipment lines, making this breaker fully compatible with legacy Series C panelboards, switchboards, and motor control centers bearing those brand names.
Are the trip settings on the HFA3035 adjustable for custom coordination?
No. This breaker utilizes a fixed thermal and fixed magnetic trip unit, meaning the long-time and instantaneous protection settings cannot be altered in the field.
What does the LI trip function code mean on this breaker?
The LI designation indicates that the thermal-magnetic trip unit provides Long-Time (L) protection against mild, sustained overloads and Instantaneous (I) protection against severe short circuits.
How is the HFA3035 secured within the panelboard?
It utilizes a bolt-on connection, meaning it bolts directly to the busbars of compatible Eaton Series C panelboards and switchboards. This provides a secure installation that is highly resistant to vibration.
What size conductors are accepted by the terminals on the HFA3035?
The factory-installed lugs accommodate wire gauges ranging from 14 AWG up to 1/0 AWG. Always verify that your selected conductor size meets the 35A circuit requirements according to local electrical codes.
