Product FAQs
5 answersWhat panels accept the QPJ3150, and how much space does it require?
The QPJ3150 is engineered specifically for Siemens EQIII 3-phase load centers. Due to its cross-over design, it requires six standard 1-inch spaces, occupying three positions on each side of the busbar.
Are the trip settings on the QPJ3150 adjustable?
No, this breaker features a non-interchangeable trip unit with fixed thermal and fixed magnetic settings for long-time and instantaneous protection.
What conductor types are supported by the QPJ3150 lugs?
The factory-installed load lugs are dual-rated for both copper and aluminum (Cu/Al) conductors, accepting wire sizes from 2 AWG up to 300 kcmil.
Is the Siemens QPJ3150 a direct replacement for legacy ITE models?
Yes. Siemens acquired ITE and maintained the QPJ product line. The Siemens QPJ3150 directly replaces older ITE QPJ3150 breakers in existing EQIII panels.
What type of protection does the QPJ3150 provide?
It utilizes thermal-magnetic trip technology to provide standard LI (Long-Time and Instantaneous) protection against overloads and short circuits.
