Product FAQs
7 answersIs the Square D Q1L260 still manufactured, or is there a direct replacement?
The Q1L260 is a legacy circuit breaker. For modern panel upgrades or replacements, the Square D QOU260 is the official equivalent, offering the same 60A, 2-pole configuration and unit-mount design.
What types of panels and enclosures are compatible with the Q1L260?
This breaker is designed specifically for legacy Square D Q1L enclosures and various OEM panels that accept Q-Frame unit-mount breakers.
How is the Q1L260 circuit breaker mounted?
It features a unit-mount design with a feed-thru connection, meaning it is bolted or screwed directly to the panel chassis or enclosure rather than snapping onto a busbar.
Do I need special lugs for aluminum wire on the Q1L260?
No, the factory-installed lugs are rated for both aluminum and copper conductors, accepting wire sizes from 8 AWG to 2 AWG.
What does the LI trip function indicate on the Q1L260?
The LI designation means the thermal-magnetic trip unit provides Long-Time thermal protection against sustained overloads and Instantaneous magnetic protection against short circuits. Both settings are fixed.
Is the Q1L260 suitable for systems requiring a high interrupting rating?
No, this breaker has a standard interrupting rating of 10kAIC at 240VAC. It must only be installed in systems where the available fault current does not exceed 10,000 amps.
Does this breaker include a Visi-Trip indicator?
Yes, like many Square D Q-Frame breakers, it features a Visi-Trip visual indicator that makes it easy to identify a tripped breaker in a crowded panel.
