ZINSCO QFP2225 225A 2P 120 240V PLUG ON CIRCUIT BREAKER

Description:

The Zinsco QFP2225 is a 225 Amp, 2-pole molded case circuit breaker designed for use in Zinsco / GTE Sylvania / Challenger load centers. It operates on 120/240V systems and features a thermal-magnetic trip mechanism that provides protection against overloads and short circuits. It belongs to the QFP series and uses a plug-in (plug-on) mounting style for installation in compatible panels. This breaker is commonly used as a main breaker and includes load-side lugs for conductor termination, with a typical interrupt rating of approximately 10 kAIC.

Applications:

The Zinsco QFP2225 breaker is commonly used in residential and commercial electrical systems as a main disconnect or feeder breaker for subpanels, service entrances, and high-capacity distribution circuits requiring 225A protection. It is specifically intended for legacy Zinsco panels and is primarily used today for maintenance or replacement of existing installations.
