Engineered for commercial power distribution, the Square D QBL32200LW is a 200A, 3-pole molded case circuit breaker. It provides reliable thermal-magnetic overcurrent protection for heavy-duty electrical systems. This unit-mount MCCB installs into Square D individual enclosures, switchboards, and panelboards. It serves as a direct replacement for legacy Q23200 breakers. Rated for 10kA at 240VAC, this Q-Frame breaker includes factory-installed control wire terminals and a Visi-Trip indicator.
What does the LW suffix indicate on the QBL32200LW catalog number?
The LW suffix designates that this breaker includes factory-installed control wire terminals on both the ON (line) and OFF (load) ends.
Can the QBL32200LW replace older Square D 200A breakers?
Yes, this PowerPacT Q-Frame breaker serves as a direct replacement for legacy Q23200 series circuit breakers.
What enclosures and panels accept the QBL32200LW breaker?
This unit-mount Q-Frame breaker is designed for installation in Square D individual enclosures, switchboards, and panelboards.
What wire sizes and materials are supported by the lugs on this 200A breaker?
The factory-installed lugs accept 4 AWG to 300 kcmil aluminum or copper conductors.
Is the QBL32200LW suitable for systems requiring high interrupting capacity?
This specific QBL model has a standard interrupting rating of 10kA at 240VAC. If your system requires a higher fault current rating, you will need to upgrade to the QDL (25kA), QGL (65kA), or QJL (100kA) series breakers.
How is the QBL32200LW mounted in a panel?
It features a unit-mount, feed-thru configuration. This means it bolts directly to the backpan or mounting surface rather than plugging onto a busbar or using an I-Line connection.
Does this breaker include a visual trip indicator?
Yes, it features a Visi-Trip indicator that provides clear visual confirmation when the breaker has tripped due to an overcurrent or short-circuit event.
What type of trip unit is installed in the QBL32200LW?
It utilizes a fixed thermal-magnetic trip unit with Long-Time (L) and Instantaneous (I) functions to protect against overloads and short circuits. Both the thermal and magnetic trip points are fixed and non-interchangeable.
