Product FAQs
8 answersWhat does the "B" in the catalog number HLXD63B500 stand for?
The "B" indicates that this circuit breaker is supplied without line and load lugs installed. If you need mechanical or compression lugs for your installation, you must source the appropriate Sentron LD-frame lug kits separately.
What does the "H" in the HLXD63B500 part number indicate?
The "H" designates this as a high-interrupting capacity breaker. It provides an elevated interrupting rating of 65kA at 480VAC and 35kA at 600VAC, which is higher than standard LD-frame circuit breakers.
Which Siemens panelboards and switchboards are compatible with the HLXD63B500?
This Sentron LD-frame breaker is designed for unit-mount configurations and fits directly into Siemens P4 and P5 panelboards, as well as Sentron switchboards and standalone enclosures.
How do I adjust the trip settings on this circuit breaker?
The thermal-magnetic (LI) trip unit features a fixed thermal setting for standard overload protection. It includes an adjustable magnetic dial that allows you to configure the instantaneous short-circuit trip threshold to match your specific load requirements.
Is the thermal-magnetic trip unit interchangeable?
No, the HLXD63B500 features a non-interchangeable trip unit built into the breaker assembly.
Is the HLXD63B500 suitable for heating, air conditioning, and refrigeration equipment?
Yes, this circuit breaker is HACR rated, meaning it is certified for use with the specific inductive motor loads typically found in commercial HVAC and refrigeration systems.
Can this breaker be used in DC systems?
Yes, in addition to its AC ratings, the HLXD63B500 is UL rated for up to 500VDC with a 25kA interrupting capacity. This makes it suitable for industrial DC control panels and certain renewable energy applications.
Can I field-install external accessories on this breaker?
Yes, the Siemens Sentron LD-frame supports a variety of field-installable internal accessories, including shunt trips, auxiliary switches, and undervoltage releases.
