The Square D QDA220701 is a molded case circuit breaker designed for overcurrent protection in electrical distribution systems. This 2-pole, 70A unit operates at 240V with a 25kA interrupting capacity, providing thermal-magnetic protection with long-time and instantaneous (LI) trip functions. The breaker features an I-Line style plug-in connection for use in I-Line panelboards, measures 6.47 in x 3 in x 3.93 in (164.34 mm x 76.2 mm x 99.82 mm), weighs 4.773 lb, and accepts wire sizes from 4 AWG to 300 MCM with lug terminals. It complies with UL, CSA, NEMA, and NOM-003-SCFI-2000 standards, and is suitable for industrial applications requiring reliable branch circuit protection in single-phase systems.
