Square D QO270 – 70A 2 Pole Miniature Circuit Breaker Last Chance

Providing essential overcurrent protection for residential and commercial applications, this 70-amp component handles heavier loads like large HVAC systems or subpanels. The thermal-magnetic trip mechanism ensures reliable performance under varying conditions. It mounts into standard QO load centers, NQ panelboards, and NQOD enclosures. The standard 3/4-inch format maintains compatibility with existing Square D infrastructure. A built-in Visi-Trip indicator clearly flags tripped status.
