Product FAQs
6 answersWhat panelboards are compatible with the Siemens QJH23B070?
This QJ-frame breaker is designed for installation in Siemens P1, P2, and P3 panelboards. It is also compatible with Siemens SB switchboards, motor control centers, and meter centers.
What does the H in the QJH23B070 catalog number signify?
The H indicates a high-interrupting rating. While standard QJ2 breakers are rated for 10kAIC at 240VAC, the QJH series provides an upgraded 22kAIC interrupting capacity.
What wire sizes and materials are approved for the QJH23B070 lugs?
The factory lugs accept 6 AWG to 300 kcmil copper conductors, or 4 AWG to 300 kcmil aluminum conductors.
How does this breaker connect to the panelboard bus?
The QJH23B070 utilizes a bolt-on connection. It bolts directly to the busbars in compatible Siemens enclosures, providing a secure mechanical and electrical connection for commercial loads.
Are the thermal and magnetic trip settings adjustable on this breaker?
No. The QJH23B070 features a fixed thermal-magnetic trip unit. Both the long-time and instantaneous trip functions are factory set and cannot be adjusted in the field.
Can this breaker replace older ITE or Gould QJH models?
Yes. Siemens acquired the ITE and Gould electrical divisions. The Siemens QJH23B070 is a direct replacement for legacy ITE and Gould breakers sharing the exact same catalog number.
