Zinsco QCAL-60N 2-Pole Molded-Case Circuit Breaker

The Zinsco QCAL-60N 2-Pole Molded-Case Circuit Breaker is a 60 Amp, 2-pole device designed for 240V, single‑phase service in Zinsco / GTE Sylvania load centers. It uses a thermal-magnetic trip to provide protection against overloads and short circuits, with an interrupt rating of approximately 10 kAIC at 240V. This plug-in (snap-in) breaker fits QC/QCAL series panels and is compatible with legacy Zinsco panelboards, commonly used on 240V branch circuits for HVAC, electric ranges, subpanels, water heaters, and large appliance loads in residential and light commercial installations. The model is obsolete/discontinued and frequently reconditioned or used in aftermarket contexts; common replacements include the Siemens Q260 2-Pole 60A Circuit Breaker.
