Description
Engineered for high-fault environments, the Siemens MQJ3200KH is a 3-pole, 200A molded case circuit breaker built for commercial applications. It utilizes fixed thermal-magnetic trip technology to deliver reliable long-time and instantaneous protection. This legacy unit installs into compatible Murray and Siemens load centers or metering equipment. For current-generation equivalents, this model crosses over to the QJH23B200. It features a high interrupting capacity of 22kAIC at 240VAC.Specifications

Product FAQs
5 answersWhat equipment accepts the MQJ3200KH breaker?
This breaker is designed for use in compatible Murray and Siemens load centers, as well as approved metering equipment that accepts this specific bolt-on frame.
Are Murray and Siemens MQJ breakers the same?
Yes. Siemens acquired Murray and phased out the Murray brand name. The MQJ3200KH is an authentic Siemens product that serves as a direct replacement for legacy Murray installations requiring this exact breaker profile.
What are the wire size requirements for the load side lugs?
The factory-installed load side lugs accommodate 6 AWG to 300 kcmil copper conductors, or 4 AWG to 300 kcmil aluminum conductors.
What does the "H" in the MQJ3200KH catalog number indicate?
The "H" designates a high-interrupting rating. It provides a 22kAIC rating at 240V, compared to the standard 10kAIC rating found on base MQJ models.
Does the MQJ3200KH have adjustable trip settings?
No. It features a non-interchangeable, thermal-magnetic trip unit with fixed long-time and instantaneous (LI) trip functions.
