Product FAQs
6 answersWhich electrical panels are compatible with the Q1270?
The Q1270 is specifically designed for legacy Square D Q1 load centers and Q1 panelboards. Its original wide-frame design is required to fit these older enclosures properly.
Is the Square D Q1 series still manufactured?
No, the Square D Q1 series is a legacy product line that has been discontinued. The Q1270 is sourced to maintain and service existing Q1 panels without requiring a complete system upgrade.
Why install a Q1270 instead of a newer QO series breaker?
The legacy Q1 series features a wider frame than modern QO breakers. Using the original Q1270 ensures an exact physical fit in older Q1 enclosures without the need for retrofitting or adapter kits.
What protection does the LI trip function provide on the Q1270?
The LI designation means the breaker uses a fixed thermal-magnetic trip unit. It provides Long-Time (L) protection against sustained overloads and Instantaneous (I) protection against short circuits.
What are the wire size requirements for the Q1270?
The breaker is equipped with lug terminals that accept 8 AWG to 2 AWG wire. It is rated for use with both aluminum and copper conductors.
How is the Q1270 installed in a panelboard?
The Q1270 is a plug-in circuit breaker. It snaps directly onto the bus bars of compatible Square D Q1 load centers and panelboards, requiring no bolting hardware for installation.
