Square D KA36200 Molded Case Circuit Breaker

This 200A breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It features a specialized plug-on connection that mounts directly to the internal I-Line bus.

Yes, the legacy K-frame KA36200 is obsolete. The direct modern replacement is the Square D PowerPact J-frame JGA36200, which provides the same 200A rating and physical I-Line compatibility for existing panelboards.

It utilizes a proprietary I-Line style plug-in connection for the line side, attaching directly to the panelboard bus without the need for traditional bolt-on hardware. The load side features standard mechanical lugs for wire termination.

The thermal magnetic trip unit features a fixed thermal element and an adjustable magnetic trip mechanism. The magnetic trip can be adjusted from a low setting of 1000A to a high setting of 2000A.

Yes, the load side lugs are factory-rated for both aluminum and copper conductors. They safely accept wire sizes ranging from 4 AWG to 350 kcmil.

No, K-frame molded case circuit breakers like the KA36200 are industrial components that use an entirely different bus connection. They will only fit in commercial I-Line switchboards and panelboards.

It is a UL Listed and CSA Certified device. It also carries a HACR rating, meaning it is tested and approved for safe use with heating, air conditioning, and refrigeration motor loads.

This breaker features a visual trip indicator. When it trips due to an overcurrent or short circuit, the operating handle moves to a central position between the ON and OFF states.

The KA36200 supports internal accessories like shunt trips, but they are typically factory-installed rather than field-installable. A breaker with a factory-installed 120V to 240V AC shunt trip will feature a specific catalog suffix, such as KA36200-1021.
