Product FAQs
6 answersDoes the JXD63B225L have an interchangeable trip unit?
No. This specific model features a non-interchangeable thermal-magnetic trip unit. If you require a breaker that allows for field-upgradable trip ratings, you will need a standard JD6 frame breaker instead.
Which lugs are included with the JXD63B225L?
This breaker comes factory-equipped with TA2J6500 line and load side lugs. These lugs accept copper or aluminum wire ranging from 3/0 AWG to 500 kcmil.
Do I need a separate mounting kit to install this breaker in a panelboard?
Yes. While the breaker includes line and load lugs, a separate strap kit or connector kit is required to mount it securely within a panelboard. The exact kit depends on your specific panel model.
What types of enclosures or panels accept the JXD63B225L?
This JD frame breaker is designed for use in Siemens Sentron panelboards, switchboards, and motor control centers.
How is the trip unit adjusted on the JXD63B225L?
This breaker 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.
Is the JXD63B225L rated for DC applications?
Yes. In addition to its AC ratings, this breaker is rated for 500VDC applications with an interrupting capacity of 25kAIC.
