Product FAQs
8 answersWhich panelboards and switchboards accept the Siemens LXD63B600?
This LD frame molded case circuit breaker is designed for unit mounting in Siemens P4 and P5 panelboards, as well as compatible Siemens switchboards.
What is the difference between the LXD63B600 and the LD63B600?
The LXD63B600 features a factory assembled, non interchangeable trip unit. The LD63B600 uses the same LD frame but includes an interchangeable trip unit, allowing for field modifications to the continuous current rating.
How does the trip unit adjustability work on this breaker?
The LXD63B600 features a thermal magnetic trip unit with a fixed thermal element for long time overload protection and an adjustable magnetic element for instantaneous short circuit protection.
What lug kits are used for termination on the LXD63B600?
The standard line and load connections for this breaker utilize TA2J6500 lug kits, which accept 3/0 AWG to 500 kcmil copper or aluminum wire.
Is the LXD63B600 breaker rated for reverse feed installations?
Yes, this circuit breaker is UL listed for reverse feed applications, meaning the line and load power connections can be safely swapped if dictated by your enclosure layout.
What does the LXD6 prefix indicate in the part number?
The LXD6 prefix designates a Siemens Sentron LD frame breaker that includes a standard interrupting capacity and a non interchangeable thermal magnetic trip unit.
Is the LXD63B600 suitable for HVAC applications?
Yes, this breaker carries an HACR rating, making it approved for multi motor group protection in commercial heating, air conditioning, and refrigeration equipment.
Is the LXD63B600 rated for 100 percent continuous current?
No, the standard LXD63B600 is an 80 percent rated breaker. For applications requiring a 100 percent continuous current rating, you must specify the LXD63B600H variant and use 90C rated copper wire.
