Product FAQs
9 answersWhich panelboards and enclosures accept the HFB3010 breaker?
The HFB3010 is a standard F-frame breaker. It mounts directly into Westinghouse F-Frame panelboards, Eaton Series C panelboards, and compatible motor control centers without requiring special retrofit adapters.
What type of conductors can be landed on the HFB3010 terminals?
The factory-installed lugs accept 14 AWG to 1/0 AWG wire. The terminals are dual-rated for either copper or aluminum conductors.
Why is this breaker listed under both Eaton and Westinghouse?
Eaton acquired the Westinghouse electrical distribution division in the 1990s. The HFB3010 utilizes the exact same F-frame design, and modern Eaton or Cutler-Hammer replacements are fully backward compatible with legacy Westinghouse installations.
Is the HFB3010 suitable for DC control circuits?
Yes, in addition to its AC ratings, this thermal-magnetic breaker is rated for up to 250VDC with a 10kAIC interrupting capacity, making it suitable for various direct current applications.
Are the trip settings adjustable on the HFB3010?
No, this breaker features a fixed thermal and fixed magnetic (LI) trip unit. The 10-amp overload and instantaneous short-circuit thresholds cannot be adjusted in the field.
What does the Mark 75 family designation mean for the HFB3010?
The Mark 75 label denotes a line of high-interrupting capacity breakers. For the HFB3010, this translates to a robust 65kAIC rating at 240VAC and 25kAIC at 480VAC, suitable for systems with higher available fault currents.
Can the HFB3010 replace standard FB or FDB breakers?
Yes, the HFB3010 shares the exact same physical F-frame footprint as standard FB, FDB, and FD breakers. It can be used as a drop-in replacement, provided the 10-amp rating and higher interrupting capacity meet your system requirements.
Does the HFB3010 provide equipment ground fault protection?
No, this model is equipped with standard long-time and instantaneous (LI) trip functions for overcurrent and short-circuit protection. It does not feature ground fault (LSIG) capabilities.
How does the HFB3010 mount into a panelboard?
This is a unit-mount, bolt-on circuit breaker. It secures directly to the panelboard bus or mounting pan using standard hardware, ensuring a rigid and reliable electrical connection.
