Product FAQs
8 answersWhat does the "L" suffix in the LXD63B600L catalog number indicate?
The "L" suffix means this circuit breaker comes assembled with factory-installed line and load lugs, specifically the TA2J6500 lug kit. If you order the standard LXD63B600 without the "L", the lugs must be ordered separately.
Is the Siemens LXD63B600L compatible with reverse feed applications?
Yes, standard Sentron LXD6 thermal-magnetic circuit breakers are suitable for reverse feed applications. You can safely backfeed this breaker in your panelboard or switchboard.
Can I swap the trip unit on the LXD63B600L if my load requirements change?
No. The LXD6 series features a factory-sealed, non-interchangeable trip unit. If you require a breaker with interchangeable trip capabilities within the same frame footprint, you must use the standard LD6 series, such as the LD63B600.
What equipment is compatible with this LD frame breaker?
The LXD63B600L is a unit-mount circuit breaker designed for direct installation into Siemens Sentron panelboards, switchboards, and individual industrial enclosures.
How do the thermal-magnetic trip adjustments work on this model?
This breaker utilizes a fixed thermal setting for long-time overload protection and an adjustable magnetic setting for instantaneous short-circuit protection. The magnetic trip range can be adjusted between 3000A and 6000A to coordinate with downstream devices.
What wire sizes are supported by the factory-installed lugs?
The included TA2J6500 lugs accept two conductors per phase. Each terminal accommodates 3/0 AWG to 500 kcmil copper or aluminum wire, allowing for parallel conductor routing in high-amperage feeds.
Can the LXD63B600L be used for HVAC equipment loads?
Yes, this molded case circuit breaker carries a Heating, Air Conditioning, and Refrigeration (HACR) rating, making it approved for protecting dedicated HVAC circuits.
Is this breaker approved for direct current (DC) systems?
Yes, the LXD63B600L is UL rated for up to 500VDC applications. It provides a 25kA interrupting capacity when deployed in qualified DC systems or battery banks.
