Description
Maintaining legacy electrical infrastructure requires exact-fit components like the Siemens JK2B200. This 200A, two-pole molded case circuit breaker delivers reliable thermal magnetic protection with an adjustable magnetic trip, ensuring precise coordination for commercial facilities. The bolt-on design mounts into Siemens P4, P5, and ITE CDP panelboards. It serves as a direct cross-reference for JD62B200 and JXD62B200 breakers. Features an 18kAIC rating at 600VAC and HACR certification.Specifications

Product FAQs
6 answersWhich panelboards accept the Siemens JK2B200 breaker?
As a legacy J-frame MCCB, the JK2B200 is backward compatible with older ITE CDP panelboards and switchboards. It is also approved for installation in newer Siemens P4 and P5 panelboards, allowing you to service existing infrastructure without a full panel retrofit.
How is the trip unit adjusted on the JK2B200?
This breaker utilizes a thermal-magnetic trip unit with an LI (Long-Time, Instantaneous) configuration. The thermal overload protection is fixed at 200 amps, while the magnetic instantaneous trip is adjustable. This allows installers to fine-tune short-circuit protection to coordinate with downstream devices.
What type of wire can be installed on the JK2B200 lugs?
The factory lugs on this breaker are dual-rated for both copper (Cu) and aluminum (Al) conductors. They accept wire sizes ranging from 4 AWG up to 300 kcmil, providing flexibility for various 200-amp feeder applications.
Is the JK2B200 rated for direct current (DC) applications?
Yes, in addition to its AC ratings, this breaker is certified for use in 250VDC systems. It provides a 10kA interrupting capacity at 250VDC, making it suitable for specific battery, solar, or industrial DC control panels.
Does the JK2B200 plug into the panel bus?
No, this is a bolt-on circuit breaker. It must be mechanically fastened directly to the busbars of a compatible switchboard or panelboard, such as a Siemens P4 or P5, to ensure a secure, high-capacity connection for 200-amp loads.
Is the JK2B200 considered an obsolete breaker?
The JK frame is part of the legacy Siemens and ITE molded case circuit breaker family. While newer frame types have been introduced for modern enclosures, the JK2B200 remains available to maintain and expand existing legacy electrical systems without requiring a complete panel upgrade.
