Product FAQs
5 answersWhat equipment is the Square D Q2L3225H designed to be installed in?
This unit-mount breaker is compatible with Square D individual enclosures, switchboards, and legacy panelboards configured for Q-Frame feed-thru breakers.
What is the modern replacement for the legacy Q2L3225H circuit breaker?
The Q2L3225H is a legacy Q-Frame model. When upgrading infrastructure, it is directly replaced by the PowerPact Q-Frame series, specifically the QDL32225. Using the original Q2L3225H is often preferred to maintain the UL listing of older legacy panels.
What wire sizes and materials are supported by the terminals on the Q2L3225H?
The feed-thru line and load lugs accept either aluminum or copper conductors ranging from 4 AWG to 300 kcmil.
How does the thermal-magnetic trip unit function on the Q2L3225H?
The breaker features a fixed thermal-magnetic trip unit with an LI configuration. This provides Long-Time protection for sustained overloads and Instantaneous protection for short circuits. Both the thermal and magnetic trip points are fixed and non-adjustable.
How is the Q2L3225H mounted within an electrical system?
It is a unit-mount breaker that utilizes a feed-thru connection type. Instead of plugging or bolting onto a busbar, it relies on cabled connections secured to the line and load side lugs.
