Providing robust thermal-magnetic protection, the Square D Q2L3200H is a 3-pole, 200A circuit breaker for heavy-duty commercial and industrial applications. Equipped with line and load lugs, this unit-mount breaker integrates into Square D NQOD panelboards and enclosures. To replace this legacy component, use the QDL32200. It delivers a high interrupting capacity of 22kA at 240VAC and features a non-interchangeable trip with Visi-Trip.

Product FAQs
7 answers
What does the 'H' signify in the Q2L3200H catalog number?
The 'H' indicates a high interrupting capacity. The Q2L3200H is rated for 22kAIC at 240VAC, which provides higher fault protection than the standard Q2L3200 model rated at 10kAIC.
Is the QDL32200 a direct replacement for the Q2L3200H?
The PowerPact QDL32200 is the modern substitute and will physically fit. However, installing a newer PowerPact Q-frame breaker in an older NQOD panel designed strictly for legacy Q2 frames may void the panelboard's UL listing. Using the exact Q2L3200H preserves the original UL listing of the equipment.
How is the Q2L3200H installed in a panelboard?
This is a unit-mount, feed-thru circuit breaker. Unlike plug-on or bolt-on branch breakers that connect directly to a panelboard bus, the Q2L3200H mounts independently and uses factory-installed lugs on both the line and load sides for wire connections.
Can the trip settings on the Q2L3200H be adjusted for specific loads?
No. The Q2L3200H features a fixed thermal-magnetic trip unit. The long-time and instantaneous (LI) trip functions are factory-set and non-interchangeable, meaning they cannot be adjusted in the field.
Which Square D panelboards are compatible with the Q2L3200H?
This breaker is compatible with legacy Square D NQOD panelboards, switchboards, and individual enclosures that are specifically designed to accept Q2-frame unit-mount breakers. It is not compatible with standard QO or Homeline load centers.
How can I visually verify if the Q2L3200H has tripped?
The Q2L3200H is equipped with a Visi-Trip indicator. When the breaker trips due to an overcurrent or short circuit, the handle moves to a center position and a high-visibility red indicator appears, allowing for quick identification of the tripped circuit.
What wire sizes and materials are compatible with the Q2L3200H lugs?
The factory-installed line and load lugs accept both aluminum and copper conductors ranging from 4 AWG to 300 kcmil.
