Product FAQs
5 answersWhat is the difference between the LMXD63B700 and the LMD63B700?
The LMXD63B700 features a factory-sealed, non-interchangeable thermal-magnetic trip unit. The standard LMD63B700 uses an interchangeable trip unit design, combining an LMD63F800 frame with an LMD63T700 trip unit. Both share the same physical dimensions and 700A rating.
Does the LMXD63B700 come with line and load lugs installed?
No, this breaker is supplied without lugs installed. You must purchase compatible LMD-frame lug kits separately, such as the TA2K500 or TA3K500, depending on your specific wire size and conductor material.
What is the adjustable magnetic trip range for this breaker?
The instantaneous magnetic trip on the LMXD63B700 can be adjusted between 3200A and 8000A. This allows for precise coordination with downstream devices and helps accommodate motor inrush currents.
What are the physical dimensions of the LMXD63B700?
This LMD-frame molded case circuit breaker measures 16.0 inches high, 7.5 inches wide, and 4.5 inches deep.
Can I install internal accessories like a shunt trip in this breaker?
Yes, the Siemens Sentron LMD frame supports field-installable internal accessories. You can add shunt trips, undervoltage releases, and auxiliary switches into the designated accessory pockets under the front cover.
