About this item
The Square D QO370 is a 3-pole, 70 A miniature circuit breaker from Schneider Electric's QO line, built for 120/240 V AC distribution with a 10 kA interrupting rating. Its thermal-magnetic trip unit opens all three poles together on an overload or short circuit, and the QO family's Visi-Trip indicator shows a red flag in the handle window so a tripped breaker can be spotted at a glance. HACR rating makes it suitable for heating, air-conditioning and refrigeration equipment circuits as well as general feeder and branch protection.
This listing is for a new, factory-sealed QO370 that plugs directly onto the bus of Square D QO load centers, NQ panelboards and Speed-D switchboards, occupying three panel spaces. Its box-lug terminals accept 8-2 AWG copper or aluminum conductors, and the breaker is UL 489 Listed and CSA Certified.
Condition: New, sealed, as listed. The photographs are of the actual unit you'll receive, covered by our warranty.
