Product FAQs
7 answersWhat types of equipment are compatible with the HFD63B175?
This FD-frame breaker is designed for installation in Siemens Sentron panelboards, switchboards, and motor control centers.
Does the HFD63B175 feature an adjustable trip setting?
Yes, it features a thermal-magnetic trip unit with a fixed thermal element and an adjustable magnetic (instantaneous) setting. This allows you to fine-tune short-circuit protection and improve system coordination.
Can the Siemens HFD63B175 be reverse fed?
No. Because this breaker features an interchangeable trip unit, it is marked with LINE and LOAD designations to comply with UL 489 standards and cannot be reverse fed. For reverse-feed applications, a non-interchangeable frame is required.
Is the Siemens HFD63B175 a direct replacement for an ITE HFD63B175?
Yes. Siemens acquired ITE and continues to manufacture the Sentron FD-frame breakers under the Siemens brand. The HFD63B175 is the exact same form factor and a direct replacement for the older ITE-branded version.
Are line and load lugs included with this breaker?
Yes, this breaker comes complete with standard line and load lugs that accept 6 AWG to 350 kcmil copper or aluminum wire.
What does the H in the HFD63B175 catalog number indicate?
The H designates this as a High Interrupting capacity breaker within the FD frame family. It provides a 65kA interrupting rating at 480V AC and 100kA at 240V AC, which is higher than standard FD6 breakers.
Can I change the amperage of this breaker later without replacing the whole unit?
Yes. The HFD63B175 comes with an interchangeable trip unit. If your load requirements change, you can swap the trip unit for a different amperage within the 250A maximum FD frame limit without removing the breaker frame from the panel.
