Zinsco QFP2225 2-Pole Plug-On Circuit Breaker

The Zinsco QFP2225 is a 225 Amp, 2-pole molded case circuit breaker designed for use in Zinsco / GTE Sylvania / Challenger load centers, featuring plug-in (plug-on) mounting for installation in compatible panels and 120/240 VAC operation. It provides protection against overloads and short circuits via a thermal-magnetic trip mechanism and an interrupt rating of approximately 10 kAIC at 240V, with LI (long-time and instantaneous) functions and load-side lugs for conductor termination. Commonly used as a main disconnect or feeder breaker for subpanels and service entrances in residential and commercial high-capacity distribution circuits, this legacy QFP series device is intended for legacy Zinsco panels and is obsolete / discontinued.
