Industrial QFP2150 Molded Case Circuit Breaker

The Industrial QFP2150 is a 150 Amp, 2‑pole molded case circuit breaker designed for plug-in installation in legacy Zinsco / GTE Sylvania / Challenger load centers. It operates on 240V systems and uses a thermal-magnetic trip mechanism with long-time and instantaneous functionality, providing protection against overloads and short circuits. The breaker is rated 240 VAC, single‑phase, with a typical interrupt rating of ~10 kAIC at 240 V and uses lug terminals for connection. Part of the QFP24 series, this 2‑pole device serves as a main or feeder overcurrent and short‑circuit protector in residential and light commercial panels and is intended for maintenance or replacement of existing installations in legacy panels rather than new construction.
