Product FAQs

5 answers
What is the modern replacement for the Q2L32125 circuit breaker?

The QBL32125 is the current direct replacement for this legacy Q-Frame breaker. However, installing the original Q2L32125 maintains the UL listing of older NQOD panelboards without requiring modifications.

How does the Q2L32125 mount inside a panel?

This is a unit mount, or feed-thru, circuit breaker. It does not plug onto a busbar. Instead, it secures directly to the enclosure backpan and requires wire connections at both the line and load side lugs.

Which panelboards are compatible with this Q-Frame breaker?

It is designed for use in legacy Square D NQOD panelboards, as well as compatible Square D switchboards and individual enclosures that accept unit mount breakers.

Does this breaker include a tripped status indicator?

Yes, it features the Square D Visi-Trip indicator. When the breaker trips due to an overcurrent or short circuit, a highly visible red flag appears in the indicator window to help quickly locate the faulted circuit.

Is the Q2L32125 suitable for HVAC equipment?

Yes, this breaker is HACR rated, making it approved for use with heating, air conditioning, and refrigeration equipment that requires group motor protection.
