Product FAQs
4 answersWhat is the difference between the Siemens LXD63B500 and the LD63B500?
The LXD63B500 is assembled with a factory-sealed, non-interchangeable trip unit. The LD63B500 utilizes an interchangeable trip unit design. Both are 500A, 3-pole breakers in the Siemens LD frame family and share identical interrupting ratings and physical dimensions.
What wire sizes are compatible with the standard lugs on this LD frame breaker?
When fitted with standard TA2J6500 mechanical lugs, this breaker accepts two conductors per phase. The accepted wire range is 3/0 AWG to 500 kcmil for both aluminum and copper conductors. Be aware that the base LXD63B500 catalog number is typically supplied without lugs, requiring them to be sourced separately.
What type of equipment is this circuit breaker designed to fit?
This unit mount LD-frame breaker is intended for installation in Siemens Sentron series panelboards, switchboards, and motor control centers. Appropriate bolt-on mounting hardware or strap kits are required depending on your specific panelboard type.
What is the adjustable trip range for the LXD63B500?
While the thermal overload is fixed at 500 amps, the instantaneous magnetic trip function is adjustable. The magnetic trip dial can be set between 3000A at the low setting and 6000A at the high setting.
