Product FAQs
7 answersDoes the HFXD63B150 come with terminal lugs?
No, the B in the catalog number indicates that this breaker is shipped with no lugs installed. You must purchase compatible lug kits separately, such as the TA1FD350A for aluminum or copper conductors, to complete the installation.
What size wire can be used with the standard TA1FD350A lug kit?
The TA1FD350A terminal lug kit accepts a single conductor per phase, accommodating 6 AWG to 350 kcmil for copper wire, and 4 AWG to 350 kcmil for aluminum wire.
Which Siemens panelboards are compatible with this breaker?
This bolt-on FD frame breaker mounts into Siemens P2, P3, S4, and S5 distribution panelboards. Proper mounting hardware or strap kits specific to your panel chassis will be required if not already provisioned.
Can I adjust the trip settings on this Sentron breaker?
Yes. While the thermal element for long-time overcurrent protection is fixed, the magnetic element is adjustable. This permits an electrician to modify the instantaneous trip threshold to coordinate with specific load characteristics or downstream devices.
Can this breaker be used in DC voltage systems?
Yes, the unit is rated for both alternating and direct current. It provides a 25kA interrupting rating at 500VDC, making it suitable for industrial DC control panels and distribution networks.
Is this breaker rated for HVAC equipment?
Yes, it carries an HACR rating. It is certified to safely protect heating, air conditioning, and refrigeration circuits by handling the momentary inrush currents generated by HVAC motor loads without experiencing nuisance trips.
Is the HFXD63B150 suitable for reverse feed applications?
Yes, this thermal magnetic breaker supports reverse feeding. However, you should always consult the specific panelboard labeling and local electrical codes before wiring the load terminals as line connections.
