Product FAQs
7 answersWhich load centers are compatible with the Zinsco QFP2200K?
This breaker is designed exclusively for legacy Zinsco and compatible Sylvania load centers that accept Type QFP plug-on main breakers. It will not fit modern panels from other manufacturers.
Is there a modern replacement available for the Zinsco QFP2200K?
Yes, the Connecticut Electric UBITBFP2002 is a direct, UL-listed aftermarket replacement designed to fit the same Zinsco load centers and provide identical 200A main breaker protection.
How does the QFP2200K connect to the panel bus?
The QFP2200K utilizes a plug-on connection to interface directly with the bus bars in Zinsco load centers, eliminating the need for bolt-on hardware during installation.
Are the terminal lugs on the QFP2200K rated for aluminum conductors?
Yes, the terminal lugs accept both copper and aluminum conductors ranging from 1 AWG up to 300 kcmil, accommodating standard 200A service entrance cables.
Is the 10kAIC rating sufficient for modern residential service entrances?
While 10kAIC at 240V was standard for legacy Zinsco residential panels, electricians must verify that the available fault current at the service entrance does not exceed 10,000 amps before installing this replacement main breaker.
Does the QFP2200K provide ground fault or arc fault protection?
No, this is a standard thermal-magnetic main breaker providing only long-time overload and instantaneous short-circuit protection. It does not include GFCI or AFCI circuitry.
Can the QFP2200K be used as a branch breaker?
No, the QFP2200K is specifically configured as a main breaker for Zinsco load centers. Its physical frame and 200A rating are intended for main service disconnect applications, not standard branch circuits.

Ordered QFP2200T breaker and paid to ship overnight. Reached out to company when breaker did not arrive on time. Although I did not get the breaker when expected, they did communicate the situation, refunded my shipping and expedited the breaker to me once it was ready for shipping. They handled the situation in the best possible way given the circumstances.
Would buy from them again.

I needed an obsolete part. They had it and sent it. Turned out it was the wrong part. Their customer service made up for it. They sent the correct part overnight and also sent a free ups label to return the wrong part. Great service! Highly recommend. And the refurbished part looked like it was in great shape.
