Product FAQs
8 answersWhat equipment is compatible with the HLMD63B700 circuit breaker?
This breaker mounts in Siemens Sentron panelboards, switchboards, and standalone enclosures designed to accept LMD frame breakers.
What wire sizes are supported by the standard lugs?
The factory-installed TA3K500 line and load lugs accept up to three 1/0 AWG to 500 kcmil copper or aluminum conductors per phase.
How is the trip unit adjusted on this breaker?
The thermal-magnetic trip unit features a fixed thermal element for long-time overcurrent protection and an adjustable magnetic element for instantaneous short-circuit protection.
Can this breaker be used in DC power systems?
Yes, the HLMD63B700 is rated for use in DC systems up to 500VDC, providing an interrupting capacity of 50kAIC.
Are the trip units on the HLMD63B700 interchangeable?
Yes, the Sentron LMD frame utilizes an interchangeable trip design. This allows the thermal-magnetic trip unit to be swapped without removing the breaker frame from the panel.
What are the physical dimensions of this LMD frame breaker?
The breaker measures 16 inches in height, 7.5 inches in width, and 4.5 inches in depth.
What safety standards apply to this Siemens breaker?
It is UL 489 listed for low-voltage power distribution and is HACR rated for heating, air conditioning, and refrigeration applications.
What is the difference between the LMD and HLMD frame breakers?
The HLMD frame offers a higher interrupting capacity than the standard LMD frame. The HLMD63B700 provides 65kAIC at 480VAC, while the standard LMD equivalent provides 50kAIC at 480VAC.
