Product FAQs
6 answersWhich panelboards are compatible with the Siemens HJXD63B350?
This breaker is designed for installation in Siemens P4 and P5 panelboards, as well as Siemens switchboards.
What is the difference between the Siemens JXD63B350 and the HJXD63B350?
The HJXD63B350 features a higher interrupting capacity. It is rated for 65kA at 480VAC, whereas the standard JXD63B350 has a lower short-circuit rating. Both share the same physical JD frame size and 350A rating.
What does the X in the HJXD63B350 catalog number indicate?
The X indicates that the breaker is supplied with a factory-installed, non-interchangeable trip unit. This design is required by UL 489 for breakers used in reverse feed applications.
What wire size is accepted by the standard lugs on the HJXD63B350?
When equipped with standard TA2J6500 or TC2J6500 lugs, this JD frame breaker accepts wire sizes from 3/0 AWG to 500 kcmil for copper or aluminum conductors.
How is the trip unit configured on the HJXD63B350?
It features a thermal-magnetic trip unit with a fixed thermal setting for the 350A continuous current and an adjustable magnetic setting for instantaneous short-circuit protection. The magnetic trip range is adjustable from 2000A to 4000A.
Can the HJXD63B350 be reverse fed?
Yes. Because it is built with a non-interchangeable trip unit, this breaker is UL Listed for reverse feed applications.
