Product FAQs
8 answersWhich panelboards and switchboards accept the Siemens HJD63B250?
This JD frame breaker is designed for installation in Siemens P4 and P5 panelboards, SB switchboards, motor control centers, and legacy Sentron panelboards.
What does the H in the HJD63B250 catalog number indicate?
The H designates this as a High Interrupting Capacity breaker within the Sentron JD frame family. It provides elevated fault protection, including a 65kAIC rating at 480VAC and 100kAIC at 240VAC.
How is the trip response configured on the HJD63B250?
This breaker features a thermal magnetic trip unit with a fixed thermal setting for long-time overload protection and an adjustable magnetic setting for instantaneous short-circuit protection. The magnetic trip is adjusted via a dial on the front face of the trip unit.
What are the acceptable wire sizes for the standard lugs on this 250A breaker?
The standard mechanical lugs accept 3/0 AWG to 500 kcmil copper conductors, or 4/0 AWG to 500 kcmil aluminum conductors.
What lug kits are compatible with the HJD63B250?
The standard aluminum body lug kit is the TA2J6500, which accepts both copper and aluminum wire. For applications requiring copper body lugs, the TC2J6500 kit is compatible with this JD frame breaker.
Does the HJD63B250 support interchangeable trip units?
Yes. This breaker features an interchangeable trip unit design. The thermal magnetic trip assembly can be removed and replaced within the JD frame if different protection characteristics are required.
Can the Siemens HJD63B250 replace older ITE brand circuit breakers?
Yes. Siemens acquired ITE and maintained the same JD frame dimensions and mounting configurations. This breaker serves as a direct replacement for legacy ITE HJD63B250 models.
Is it safe to adjust the magnetic trip settings while the breaker is energized?
No. To prevent unintended tripping and mitigate arc flash hazards, all trip adjustments must be performed while the circuit breaker is de-energized and properly locked out.
