Description
Operating as a crucial component in legacy power distribution, this 200A J-frame breaker delivers consistent thermal-magnetic protection. It integrates into ITE CDP switchboards and Siemens P4 or P5 panels, offering a seamless hardware match for older enclosures. With an interrupting rating of 22kA at 480VAC, the unit handles demanding industrial loads while featuring an adjustable magnetic trip. The JD63B200 serves as the primary factory-recommended substitute for this exact model.Specifications

Product FAQs
7 answersIs there a direct replacement for the legacy JK3B200 circuit breaker?
Yes, the Siemens JD63B200 is the primary factory-recommended substitute for the JK3B200. It provides the same 200A rating and fits similar J-frame applications.
What type of panelboards can the JK3B200 be installed in?
This breaker is designed for use in Siemens P4 and P5 panelboards, as well as legacy ITE CDP panelboards and switchboards.
Can I use the JK3B200 in a standard residential load center?
No, the JK3B200 is a bolt-on molded case circuit breaker designed for commercial and industrial distribution equipment, not residential load centers.
Can I adjust the trip settings on the JK3B200?
The JK3B200 features a thermal-magnetic trip unit with a fixed thermal setting for long-time overload protection, but it includes an adjustable magnetic dial for instantaneous short-circuit protection.
Can the JK3B200 be used in DC power systems?
Yes, in addition to its AC ratings, this breaker is rated for use in 250VDC systems and provides a 10kA interrupting capacity for direct current applications.
Are the lugs on the JK3B200 rated for aluminum wire?
Yes, the standard lugs are dual-rated for both copper and aluminum conductors, accepting wire sizes from 4 AWG up to 300 kcmil.
Does the JK3B200 plug into the panelboard busbar?
No, this is a bolt-on circuit breaker. It must be mechanically bolted to the busbars in compatible Siemens or ITE panelboards, ensuring a secure connection for high-amperage industrial applications.
