Zinsco UBIZ280 – 80A 2 Pole Miniature Circuit Breaker Budget

Built to accommodate high-amperage residential circuits, this 80A two-pole breaker fits perfectly into vintage Zinsco and Sylvania Type QC enclosures. The thick-series profile maintains the exact dimensions required for older panelboards. This component serves as a reliable substitute for obsolete QC80 and QCAL80 models. It mounts into the panel without any aftermarket modification. The breaker provides a 10kAIC rating at 120/240VAC and includes a common trip mechanism for enhanced safety.
