Product FAQs
9 answersDoes the LMD63F800 include a trip unit and lugs?
No, the LMD63F800 is a breaker frame only. It requires a compatible interchangeable thermal-magnetic trip unit (such as the LMD63T800) and line and load lugs (such as the TA3K500) to function as a complete circuit breaker.
Which trip units are compatible with the LMD63F800 frame?
This frame accepts Siemens Sentron LMD63T series interchangeable thermal-magnetic trip units, which are available in continuous current ratings from 500 to 800 amps.
What lug kits are approved for use with this breaker frame?
The LMD63F800 frame is commonly paired with TA3K500 lugs, which accept one to three #1/0 AWG to 500 kcmil Cu/Al cables per phase, or TA2K500 lugs, which accept one or two #1 AWG to 500 kcmil Cu/Al cables.
What is the difference between the LMD63F800 and the HLMD63F800?
The LMD63F800 is the standard interrupting capacity frame rated at 50kA at 480VAC. The HLMD63F800 is the high interrupting capacity version rated at 65kA at 480VAC. Both share the same physical dimensions and accept the same trip units and accessories.
What is the difference between the LMD63F800 and the LMXD63B800?
The LMD63F800 is a frame only that requires a separate interchangeable trip unit. The LMXD63B800 is a complete, factory-assembled circuit breaker that features a non-interchangeable thermal-magnetic trip unit.
What are the physical dimensions of the LMD63F800 frame?
The Siemens LMD frame measures 16 inches in length, 7.5 inches in width, and 4.5 inches in depth. The depth extends to 5.93 inches when including the handle.
Can this frame be used in DC power applications?
Yes, the LMD63F800 frame is rated for up to 500VDC. When used in 500VDC applications, it is specifically UL listed for ungrounded UPS systems and must be wired according to Siemens guidelines.
Are internal accessories pre-installed in the LMD63F800?
No, the LMD63F800 is a base frame only. Internal accessories such as shunt trips, undervoltage releases, auxiliary switches, and alarm switches are field-installable and must be sourced separately.
What standalone enclosure is compatible with the LMD63F800?
The LMD63F800 frame can be mounted in a Siemens LMD1 enclosure. This is a NEMA 1 rated housing designed specifically for 3-pole LMD and HLMD series circuit breakers up to 800 amps.
