Product FAQs
5 answersWhat enclosures accept the Zinsco QFL2225?
The QFL2225 is designed for installation in legacy Zinsco, Sylvania, and Challenger panelboards or switchboards configured for QFL-series feed-thru main breakers.
How is the Zinsco QFL2225 mounted?
It utilizes a feed-thru connection type. Instead of plugging onto a busbar or bolting to a chassis, the line and load conductors are wired directly into the breaker's terminal lugs.
What trip functions are included on the QFL2225?
This breaker features a fixed thermal-magnetic trip unit that provides long-time protection for overloads and instantaneous protection for short circuits.
Is the Zinsco QFL2225 still in production?
No, original Zinsco circuit breakers are obsolete. When replacing this frame, electricians typically source surplus original units or use modern aftermarket equivalents manufactured by Connecticut Electric.
Are there safety concerns with legacy Zinsco panels?
Yes. Legacy Zinsco electrical panels have a documented history of busbar arcing and breakers failing to trip under overcurrent conditions. Licensed electricians often recommend a complete panel upgrade rather than replacing individual breakers.
