Product FAQs
7 answersWhich Siemens enclosures and panelboards can accommodate the HFXD63B100?
It is directly compatible with Siemens P1, P2, P3, P4, and P5 panelboards, as well as S4, S5, SPP, and FPP switchboards and motor control centers.
Is the HFXD63B100 designed for I-T-E plug-in panelboards or unit mounting?
This specific breaker features a unit mount design with a bolt-on connection. It is intended for use in standalone enclosures, switchboards, and specific bolt-on panel configurations rather than standard plug-in load centers.
Does the HFXD63B100 offer adjustable trip settings?
Yes. While its thermal long-time protection for overload is fixed at 100 amps, it includes an adjustable magnetic instantaneous trip function. This allows customization for specific short-circuit and inrush current requirements.
Can the HFXD63B100 be utilized in DC electrical systems?
Yes, this molded case circuit breaker is rated for direct current applications up to 500VDC, providing a 25kA interrupting capacity for specialized industrial DC networks.
What does the H prefix signify in the HFXD63B100 part number?
The H prefix indicates it is a high-interrupting capacity breaker within the Sentron FD frame family. The HFD frame delivers up to 65kAIC at 480VAC, which is a higher short-circuit rating than standard FXD models.
Is the HFXD63B100 approved for heating, air conditioning, and refrigeration equipment?
Yes, this circuit breaker is HACR rated, ensuring it safely handles the unique inrush currents generated by HVAC group motor applications.
What is a modern replacement option for the HFXD63B100?
The legacy HFD frame HFXD63B100 is frequently upgraded to the newer Siemens 3VA5210-6EC31-0AA0. The 3VA52 model provides identical 100A and voltage specifications, though a different mounting adapter kit may be required depending on the existing panelboard structure.
