Product FAQs
6 answers
What does the H in the QJH22B100 catalog number indicate?
The H designates this as a high interrupting QJH2 type breaker with a 22kAIC rating at 240V. Standard QJ2 breakers without the H have a lower 10kAIC rating.
Which Siemens panelboards are compatible with the QJH22B100 circuit breaker?
This bolt-on breaker is designed for use in Siemens P1, P2, and P3 panelboards, as well as SB switchboards, motor control centers, and meter centers.
What wire sizes and materials are accepted by the lugs on the QJH22B100?
The factory lugs accept copper wire from 6 AWG up to 300 kcmil, and aluminum wire from 4 AWG up to 300 kcmil.
Can the Siemens QJH22B100 replace older ITE brand breakers with the same catalog number?
Yes. Siemens acquired ITE and continued manufacturing the QJ frame. The Siemens QJH22B100 is a direct replacement for older ITE QJH22B100 breakers.
Are the thermal and magnetic trip settings adjustable on this breaker?
No. The QJH22B100 features fixed thermal and fixed magnetic trip functions. The long time and instantaneous trip points cannot be adjusted in the field.
Is this 2-pole breaker suitable for single-phase applications?
Yes. The QJH22B100 is a 2-pole, 240VAC breaker specifically designed for single-phase electrical systems.
