Product FAQs
9 answersWhich Siemens panelboards are compatible with the QJH22B225 circuit breaker?
This bolt-on breaker is designed for use in Siemens P1, P2, and P3 panelboards, as well as compatible switchboards, motor control centers, and meter centers.
What does the "H" in the QJH22B225 part number indicate?
The "H" designates this as a high-interrupting capacity breaker. It features a 22kAIC rating at 240VAC, compared to the standard 10kAIC rating found on standard QJ22B225 breakers.
What wire sizes and materials are accepted by the lugs on this breaker?
The standard lugs accept wire gauges from 6 AWG up to 300 kcmil. They are compatible with both copper and aluminum conductors.
Is the QJH22B225 a suitable replacement for older QJ frame breakers?
Yes, it shares the same physical footprint and mounting configuration as older QJ frame breakers, making it a direct drop-in replacement for equivalent 225A, 2-pole models.
What is the difference between the QJH22B225 and the QRH22B225?
The QRH22B225 is the newer generation replacement for the legacy QJH22B225. Both share the same form factor and mounting style, allowing the QRH frame to easily retrofit into panels originally designed for QJ or QJH breakers.
Can the QJH22B225 be reverse fed?
Yes, Siemens QJ and QJH frame molded case circuit breakers feature non-interchangeable trip units and are UL listed for reverse feed applications.
Does this breaker include a removable trip unit?
No, the QJH22B225 is built with a fixed thermal-magnetic trip unit. The non-interchangeable design is required to maintain its UL listing for reverse feed applications.
What type of trip protection does the QJH22B225 provide?
It utilizes a thermal-magnetic trip unit that provides both Long-Time (thermal) and Instantaneous (magnetic) protection against overloads and short circuits. Both the thermal and magnetic trip points are fixed.
Is the QJH22B225 HACR rated?
Yes, Siemens QJ and QJH frame breakers are HACR rated, making them suitable for use with heating, air conditioning, and refrigeration equipment.
