A 30-amp circuit that won't handle the load it was designed for trips constantly and creates callbacks — or worse, one that doesn't trip when needed creates a fire hazard. This 30-amp single-pole Square D breaker is built for the thermal and magnetic trip thresholds that code requires for 30-amp 120V circuits — dryers, ranges, and dedicated equipment circuits. The Square D thermal-magnetic trip element is the reference standard in the industry for residential and light commercial panels. Electricians across northeast Nebraska and northwest Iowa trust it because it does its job. In stock at Crofton Lumber (Crofton, NE) and Akron Lumber (Akron, IA) — ready for pickup today.
