Product FAQs
7 answersWhat panelboards are compatible with the QJH22B090?
This QJ-frame breaker is designed for bolt-on installation in Siemens P1, P2, P3, P4, and P5 panelboards, as well as compatible switchboards and meter centers.
What does the H in the QJH22B090 catalog number signify?
The H indicates a high interrupting rating. While the standard QJ22B090 is rated at 10kAIC at 240VAC, the QJH22B090 provides a higher 22kAIC rating for systems with greater available fault current.
Are there other interrupting ratings available for this 90A QJ-frame breaker?
Yes. If your system requires a different short-circuit rating, the standard QJ22B090 offers 10kAIC, and the QJ22B090H provides an extra-high 42kAIC at 240VAC.
What wire sizes are accepted by the lugs on the QJH22B090?
The load-side lugs accept 6 AWG to 300 kcmil copper wire, or 4 AWG to 300 kcmil aluminum wire.
Can the QJH22B090 be reverse fed?
Yes, this thermal-magnetic breaker supports reverse feed installations, allowing for greater flexibility when wiring your panel or enclosure.
Is this breaker suitable for heating and cooling equipment?
Yes, the QJH22B090 is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires HACR-type circuit protection.
What type of trip unit is equipped on this breaker?
It features a non-interchangeable thermal-magnetic trip unit providing standard Long-Time and Instantaneous (LI) overcurrent and short-circuit protection.
