Product FAQs
8 answersWhat does the "H" in the HFD63B110 catalog number indicate?
The "H" designates this as a High Interrupting Capacity breaker. It provides a 65kAIC rating at 480VAC, which is higher than standard FD frame breakers.
What do the letters and numbers in the HFD63B110 part number mean?
"HFD" indicates a high-interrupting 250A frame size, "6" stands for the 600V maximum voltage rating, "3" indicates three poles, "B" means it comes factory-assembled with lugs, and "110" is the 110-amp continuous current rating.
Can I use the Siemens HFD63B110 to replace older I-T-E circuit breakers?
Yes, Siemens Sentron HFD frame breakers are direct replacements for legacy I-T-E HFD and FD frame breakers with matching specifications.
Is the Siemens HFD63B110 suitable for reverse-feed applications?
Yes, this breaker is reverse-feed capable, allowing it to be back-fed in compatible panelboards or enclosures.
How does the adjustable magnetic trip function work on this breaker?
The HFD63B110 features a fixed thermal trip for overload protection and an adjustable magnetic trip. The adjustable magnetic setting allows you to fine-tune the instantaneous short-circuit response to prevent nuisance tripping from motor inrush currents.
What type of wire can be used with the factory-installed lugs on this breaker?
The included lugs accept both copper (Cu) and aluminum (Al) conductors. Supported wire sizes range from 6 AWG to 350 kcmil for copper, and 4 AWG to 350 kcmil for aluminum.
Which electrical distribution equipment is this breaker designed for?
The HFD63B110 is designed for bolt-on installation in Siemens Sentron panelboards, switchboards, and motor control centers.
What safety precautions should be taken before installing the HFD63B110?
Always de-energize the panelboard or switchboard before installation. Verify that the available fault current at the installation point does not exceed the breaker interrupting ratings, such as 65kAIC at 480V or 25kAIC at 600V.
