Product FAQs
6 answersWhat is the modern replacement for the legacy Q2L3110 circuit breaker?
The Q2L3110 is a legacy Q-frame breaker that has been replaced by the newer PowerPact QBL32110 catalog number. However, installing the exact Q2L model is often preferred to preserve the original UL listing of legacy panelboards and enclosures.
Which enclosures are compatible with this Q2-series breaker?
This unit-mount breaker is designed for compatible Square D panelboards, switchboards, and individual Q2-series enclosures, including catalog numbers Q23225NS, Q23225NRB, and Q23225NF.
How is the feed-thru connection configured on this breaker?
The feed-thru design means the breaker is equipped with mechanical lugs on both the line and load sides. This allows for direct wire termination on both ends, making it ideal for individual mounting where a busbar connection is not used.
Does upgrading to a newer PowerPact breaker affect the enclosure's short-circuit rating?
It can. While modern PowerPact Q-frame breakers physically fit into legacy Q2 enclosures, using a substitute breaker may introduce restrictions regarding the short-circuit rating. Using the original Q2L3110 ensures full compliance with the legacy equipment's original safety listings.
Is the Q2L3110 rated for HVAC applications?
Yes, this circuit breaker is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment that requires specialized overcurrent protection.
Does this breaker include a visual trip indicator?
Yes, the Q2L3110 features the Square D Visi-Trip indicator. This provides a highly visible red flag on the face of the breaker when it trips, allowing electricians to quickly identify a fault in a crowded panel.
