Product FAQs
7 answersWhat does the M in the LXD63M600 catalog number indicate?
The M suffix indicates that this breaker is calibrated for a 50 C (122 F) ambient temperature. This is often required for specific industrial, mining, or marine applications, whereas standard breakers like the LXD63B600 are calibrated for 40 C.
Which lug kits are compatible with this LD frame breaker?
The LXD63M600 requires external lugs for termination. A commonly used compatible lug kit is the Siemens TA2J6500, which accepts two 3/0 AWG to 500 kcmil copper or 4/0 AWG to 500 kcmil aluminum conductors per phase.
Can this circuit breaker be reverse fed?
Yes, as a standard thermal magnetic molded case circuit breaker, the LXD63M600 is reverse-feed capable and can be wired with the line side on either the top or bottom terminals.
What enclosures and panelboards accept the LXD63M600?
This LD frame breaker is designed to mount in Siemens Sentron series distribution equipment, including P4 and P5 panelboards, switchboards, and motor control centers.
Are the trip settings on this breaker adjustable?
Yes, while the thermal overload protection is fixed at 600A, the magnetic short-circuit trip function is adjustable. This allows for precise coordination with upstream and downstream protective devices in your electrical system.
Can I swap the trip unit on this breaker?
No, the LXD63M600 features a non-interchangeable trip unit. The thermal magnetic trip mechanism is factory sealed and cannot be replaced or upgraded in the field.
Is the LXD63M600 suitable for HVAC applications?
Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires this specific certification.
