Applications

The Square D QOU series is a line of plug-in miniature circuit breakers designed for use in Square D QO and QOU load centers and panelboards. QOU breakers are commonly used in residential and light commercial electrical panels to provide overcurrent and short-circuit protection for branch circuits. Two-pole breakers like the QOU225 protect 240V circuits such as dryers, water heaters, air conditioners, and other double-pole loads. The QOU series is a widely-installed standard in North American residential construction and remains in active use for panel maintenance, replacement, and retrofit work. Because Square D load centers are among the most common in U.S. homes, replacement breakers like this are frequently needed by electricians, contractors, and homeowners maintaining existing panels.
