Product FAQs
8 answersWhat wire sizes are compatible with the standard lugs on the JXD62B225?
When fitted with the standard TA2J6500 line and load lugs, the breaker accepts 3/0 AWG to 500 kcmil copper or aluminum wire.
Can the Siemens JXD62B225 be reverse fed?
Yes, JXD6 series circuit breakers are UL listed for reverse feed applications, allowing flexibility in mounting orientation and wiring.
How should the JXD62B225 be wired for 250VDC applications?
When applying this breaker on 250VDC systems, it is standard practice to use both poles, connecting one pole to each leg of the DC supply circuit.
What does the X in the JXD62B225 catalog number indicate?
The X signifies that the breaker is factory assembled with a non-interchangeable thermal-magnetic trip unit. If your application requires an interchangeable trip unit, you would need the standard JD62B225 frame and a separate trip unit.
Is the JXD62B225 rated for 100 percent continuous current?
No, this standard model is rated for 80 percent continuous current. Applications requiring a 100 percent rating need the HJXD62B225 variant, which also mandates the use of 90 degree Celsius copper cable sized at 75 degree Celsius ampacity.
Which Siemens panelboards accept the JXD62B225 breaker?
This JD frame unit mounts into Siemens Sentron series panelboards, specifically the P4, P5, S4, and S5 types, as well as compatible motor control centers and switchboards.
What is the modern replacement for the legacy Sentron JXD62B225?
Siemens has transitioned the legacy Sentron JD frame breakers to the newer 3VA series platform. The 3VA molded case circuit breakers offer a nearly identical footprint for straightforward upgrades in existing electrical apparatus.
Is the JXD62B225 suitable for HVAC applications?
Yes, this breaker carries an HACR rating, making it approved for use with heating, air conditioning, and refrigeration equipment group motor loads.
