Product FAQs
8 answersWhich Siemens panelboards accept the HHFXD63B100 circuit breaker?
This bolt-on breaker is compatible with Siemens P2, P3, P4, and P5 panelboards, as well as Siemens switchboards. Note that proper FD frame mounting strap kits are required for installation.
What does the HHF prefix indicate on this Sentron series breaker?
The HHF designation signifies a high-interrupting FD frame breaker. It provides an elevated interrupting capacity of 100kAIC at 480VAC and 25kAIC at 600VAC compared to standard FD frame models.
How does the adjustable trip function operate on the HHFXD63B100?
This breaker utilizes a thermal-magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection. The magnetic trip range can be adjusted between 700A and 1200A.
Is the trip unit on this FD frame breaker interchangeable?
No, the HHFXD63B100 is manufactured with a non-interchangeable trip unit. The thermal-magnetic components are factory sealed and cannot be swapped in the field.
What is the ambient temperature calibration for this circuit breaker?
The HHFXD63B100 is assembled and calibrated for a standard operating temperature of 40 degrees Celsius (104 degrees Fahrenheit).
Does this breaker require a specific mounting kit for panelboard installation?
Yes, while it features a standard bolt-on connection, installing this FD frame breaker into Siemens panelboards like the P2 or P3 requires the corresponding panel-specific mounting strap kit or hardware.
Can the HHFXD63B100 replace standard FXD6 or HFD6 circuit breakers?
Yes, because it shares the same physical FD frame dimensions, the HHFXD63B100 can physically replace standard FXD6 or HFD6 breakers. It serves as a direct upgrade for applications requiring a higher interrupting capacity, up to 100kAIC at 480VAC.
Are line and load lugs included with the HHFXD63B100?
The B suffix in the catalog number indicates this breaker is factory-supplied without lugs. Line and load lugs must be sourced separately based on your specific wire size and conductor material requirements.
