Product FAQs
8 answersWhat is the difference between the Siemens JXD63225 and the JXD63B225?
The B in the catalog number JXD63B225 indicates that the breaker is supplied from the factory without terminal lugs installed. Aside from the terminal configuration, the base JD frame breaker and its protective characteristics are identical.
Which terminal lugs are compatible with this JD frame circuit breaker?
If you need to add line and load terminals, the Siemens TA2J6500 aluminum lug kit is widely used for JD frame models. This kit accepts one cable per pole, accommodating 3/0 AWG to 500 kcmil copper or 4/0 AWG to 500 kcmil aluminum wire.
Can I add internal accessories to the JXD63B225 breaker?
Yes, this Sentron series circuit breaker supports field-installable accessories. Panel builders can add shunt trips, auxiliary switches, alarm switches, and undervoltage releases to meet specific control requirements.
How does the trip adjustability function on the JXD63B225?
This unit features a fixed thermal element for long-time overload protection and an adjustable magnetic element. The magnetic trip allows you to dial in the instantaneous short-circuit response, which helps coordinate with specific motor inrush currents.
Can this Siemens circuit breaker be reverse fed?
Yes, this molded case circuit breaker is reverse feed capable. You can wire the line and load connections in either direction without compromising the thermal magnetic protection.
Is the trip unit on this breaker interchangeable?
No, this specific model features a non-interchangeable trip unit. The 225A thermal magnetic assembly is built into the frame and cannot be swapped for a different amperage rating.
Is this circuit breaker HACR rated?
Yes, it is HACR rated. This certification ensures the breaker is safe and approved for use with heating, air conditioning, and refrigeration equipment in commercial and industrial environments.
Has the Siemens JXD6 series been replaced by a newer model?
The JXD6 and Sentron JD frame breakers are considered legacy models by Siemens and are officially being transitioned to the newer 3VA series molded case circuit breakers. However, the JXD63B225 remains widely used for maintaining and expanding existing Sentron installations.
