Engineered for commercial power distribution, the Siemens QJH22B200 is a 200A molded case circuit breaker from the QJ frame series. It provides reliable thermal-magnetic protection for heavy-duty electrical systems requiring 240VAC operation. This bolt-on MCCB mounts into Siemens P1, P2, and P3 panelboards, switchboards, and meter centers. Note that this legacy QJH breaker has been replaced by the QRH22B200 model. Featuring a 22kAIC rating, it safely handles high short-circuit conditions.
What is the difference between the Siemens QJ22B200 and the QJH22B200?
The primary difference is the short-circuit interrupting rating. The QJ22B200 is rated at 10kAIC at 240V, while the QJH22B200 features a higher interrupting capacity of 22kAIC at 240V. Both share the same physical QJ frame dimensions and mounting hardware.
Can I install the QJH22B200 in a standard residential load center?
No. The QJH22B200 is a bolt-on molded case circuit breaker designed for commercial and industrial distribution equipment, such as Siemens P1, P2, and P3 panelboards or switchboards. It is not compatible with standard plug-on residential load centers.
Does the QJH22B200 require a mounting kit for panelboard installation?
Yes. When installing this QJ frame breaker into Siemens P1, P2, or P3 panelboards, a compatible strap or mounting hardware kit (such as the MBKQJ series for original P1 panels) is required to properly bolt the breaker to the busbars.
Is the QJH22B200 circuit breaker suitable for reverse feeding?
Yes. Because the QJH22B200 features a factory-sealed, non-interchangeable thermal-magnetic trip unit, it is suitable for reverse-feed applications (such as back-fed main breakers) in accordance with UL 489 standards.
Will the Siemens QJH22B200 replace older ITE brand QJ breakers?
Yes. Siemens acquired ITE and retained the QJ frame design. The QJH22B200 is a direct physical and electrical replacement for older ITE QJH22B200 or equivalent 200A QJ-frame breakers.
Are the thermal and magnetic trip settings on the QJH22B200 adjustable?
No. This breaker is equipped with a fixed thermal and fixed magnetic trip unit. The long-time (overload) and instantaneous (short-circuit) trip functions are factory-calibrated and cannot be adjusted in the field.
Can the QJH22B200 be used as a main breaker?
Yes, this 200A breaker can be utilized as a main breaker in compatible Siemens panelboards or meter centers, provided the enclosure and mounting hardware (such as a main breaker hold-down kit or strap) are rated for a QJ frame main.
