From $46.69In stock
Product Description
This tandem miniature circuit breaker is designed for use in Square D QO load centers, NQ/NQOD panelboards, and compatible Speed-D switchboard interiors. It provides two 20 A branch circuits in a single 1-pole space, making it ideal where panel capacity is limited. The unit is plug-in mounted and uses standard lug terminations on the load side for straightforward installation. It is rated 120/240 VAC, 50/60 Hz, with a 10 kA interrupting capacity, and employs a thermal-magnetic trip mechanism for reliable overcurrent protection. Typical applications include residential and light commercial distribution where high-density circuiting and QO form factor are required. The compact body measures approximately 0.75 x 2.91 x 3.5 inches and is built to the QO frame standard. Packaged one per unit, this breaker aligns with QO2020 specifications from Schneider Electric for tandem replacement and expansion scenarios.
