Square D QGA32070 is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in three-phase industrial power distribution systems. It features a 70A current rating and a 240V AC voltage rating, with a robust thermal-magnetic trip unit providing both long-time and instantaneous (LI) protection functions. The breaker is constructed with a compact Q-frame size, measuring 164.34 mm H x 114.3 mm W x 99.82 mm D and weighing 6.68 lb, and utilizes a convenient I-Line style plug-in connection with lug terminals compatible with AWG 4 to 300 kcmil aluminum or copper conductors. It complies with UL, CSA, NEMA, and NOM-003-SCFI-2000 standards and is rated for an interrupting capacity of 65kA at 240V in an operating temperature range of -25 to 70 °C (-13 to 158 °F). This breaker is typically applied in industrial panelboards and switchboards for protecting feeder and branch circuits.
