Product FAQs
7 answersWhich panelboards are compatible with the QJ22B090H circuit breaker?
This bolt-on breaker is designed for use in Siemens P1, P2, and P3 panelboards, as well as compatible Siemens meter centers and enclosures.
What is the difference between the Siemens QJ22B090 and the QJ22B090H?
The H in the QJ22B090H catalog number indicates a high interrupting rating. The standard QJ22B090 is rated at 10kAIC at 240VAC, while the QJ22B090H provides a 42kAIC rating at 240VAC for systems with higher available fault currents.
Can the QJ22B090H be used in reverse feed applications?
Yes, Siemens QJ frame molded case circuit breakers are UL Listed for reverse feed applications, allowing them to be backfed when required by the system design.
Can this breaker replace an older ITE QJ22B090H?
Yes. Siemens acquired ITE and continued manufacturing the QJ frame under the Siemens brand. A modern Siemens QJ22B090H is a direct, interchangeable replacement for an original ITE breaker with the exact same catalog number.
Does this breaker mount on a standard DIN rail?
No, the QJ22B090H features a bolt-on connection designed specifically for Siemens panelboard chassis and is not compatible with DIN rail mounting.
Is the QJ22B090H suitable for HVAC equipment?
Yes, Siemens QJ frame circuit breakers carry an HACR rating, making them suitable for group motor applications like heating, air conditioning, and refrigeration equipment.
Can the trip settings on the QJ22B090H be adjusted in the field?
No. It is equipped with a non-interchangeable thermal-magnetic trip unit. The long-time and instantaneous (LI) trip settings are fixed at the factory and cannot be adjusted or swapped out.
