Product FAQs
7 answersWhich Siemens panelboards and switchboards are compatible with the HJD63B225?
This unit-mount breaker is designed for installation in Siemens P4 and P5 panelboards, SB series switchboards, and Siemens motor control centers. It is also backward compatible with legacy Sentron panelboards that accept JD frame breakers.
What is the difference between the HJD63B225 and a standard JD63B225 breaker?
The HJD63B225 features a high interrupting rating of 65kA at 480VAC, whereas the standard JD63B225 has a standard interrupting rating of 35kA at 480VAC. Both share the same physical JD frame dimensions and mounting footprint.
How is the trip unit configured on this breaker?
It 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. The magnetic trip threshold can be adjusted using the dial on the front of the breaker.
What are the acceptable wire sizes for the standard lugs on this breaker?
The standard mechanical lugs accept 3/0 AWG to 500 kcmil copper conductors, or 4/0 AWG to 500 kcmil aluminum conductors. Ensure proper torque specifications are followed during installation.
Can this breaker replace older I-T-E Sentron JD frame breakers?
Yes. Siemens acquired I-T-E and continued the Sentron product line. The HJD63B225 serves as a direct replacement for older I-T-E branded breakers with the exact same catalog number.
Is this a plug-in or bolt-on breaker?
The HJD63B225 is a unit-mount breaker. It bolts directly to the chassis or mounting pan in switchboards and large panelboards, rather than plugging into a busbar like smaller branch breakers.
Is this breaker rated for direct current (DC) applications?
Yes, it carries a DC interrupting rating of 35kA at 500VDC, making it suitable for specific industrial DC control panels and battery systems. Always verify the specific wiring configuration required for DC switching.
