Product FAQs
5 answersWhat is the difference between the Siemens HLMD63B800 and the standard LMD63B800?
The HLMD63B800 is the high-interrupting version of the Sentron LMD frame. It is rated at 65kAIC at 480VAC and 50kAIC at 600VAC, whereas the standard LMD63B800 has lower interrupting ratings. Both breakers share the identical physical dimensions and mounting footprint, making the HLMD version a direct physical upgrade for systems requiring higher short-circuit capacities.
Can I use this breaker to replace an older ITE LMD frame breaker?
Yes, Siemens Sentron LMD frame circuit breakers are direct physical replacements for legacy ITE Imperial LMD breakers. They maintain the same physical dimensions, mounting hardware, and lug spacing to preserve your existing electrical design.
How many conductors does the standard TA3K500 lug kit accept for this 800A breaker?
The standard line and load lugs accept three 1/0 AWG to 500 kcmil copper or aluminum conductors per phase. This multiple-conductor arrangement is necessary to safely carry the 800-amp continuous current rating.
Does this thermal-magnetic trip unit allow for field adjustments?
Yes. While the long-time thermal setting for continuous current is fixed, the HLMD63B800 includes an adjustable instantaneous magnetic trip dial on the face of the breaker to fine-tune short-circuit protection based on your specific load requirements.
What types of equipment are designed to house the HLMD63B800 breaker?
This LMD frame unit is primarily designed for unit-mount installations in Siemens Sentron P4 and P5 panelboards, as well as SB1, SB2, and SB3 switchboards and enclosed assemblies.
