Description
The Siemens HLMXD63B700 is a high-capacity 700A, 3-pole molded case circuit breaker built on the proven Sentron LMD frame. It utilizes a non-interchangeable thermal-magnetic trip unit to deliver precise long-time and instantaneous (LI) protection. Designed for seamless integration, this unit mounts into Siemens Type P4 and P5 panelboards and switchboards. With a 65 kAIC rating at 480VAC and reverse feed capabilities, it meets demanding commercial requirements. Lugs must be sourced separately.Specifications

Product FAQs
7 answersWhat Siemens panelboards are compatible with the HLMXD63B700?
This LMD frame breaker is designed for use in Siemens Sentron Type P4 and P5 panelboards, as well as compatible switchboards and enclosures.
Does the HLMXD63B700 come with lugs installed?
No, this breaker is supplied from the factory without lugs. Mechanical lugs must be purchased separately based on your specific wire size and material requirements.
Can the HLMXD63B700 be used in DC electrical systems?
Yes, this breaker is rated for up to 500VDC with an interrupting capacity of 50kAIC, making it suitable for industrial DC applications, battery storage, or solar systems.
What is the difference between the HLMXD63B700 and the LMXD63B700?
The H in the catalog number designates a high interrupting capacity. The HLMXD63B700 provides a 65kAIC rating at 480VAC, whereas the standard LMXD63B700 offers a lower interrupting rating. Both share the same physical LMD frame dimensions.
Is the trip unit on the HLMXD63B700 interchangeable?
No, the B in the catalog number indicates it has a factory assembled, non-interchangeable thermal magnetic trip unit. This design complies with UL 489 requirements for reverse feed applications.
What does the LI trip function code mean for this breaker?
LI stands for Long-Time and Instantaneous protection. While the thermal overload is fixed at 700A, the magnetic short-circuit pickup is adjustable, allowing for coordination with other protective devices in the system.
Is the HLMXD63B700 suitable for reverse feed applications?
Yes, because it features a non-interchangeable trip unit, it meets UL 489 requirements for reverse feeding, allowing it to be back-fed in compatible panelboards or enclosures.
