Product FAQs
7 answersWhat is the direct replacement for the obsolete Zinsco QC60 circuit breaker?
The Connecticut Electric UBIZ260 is the exact, newly manufactured cross reference for the Zinsco QC60. It is designed to fit the same panels and provides identical 60A, 2-pole protection.
Which electrical panels are compatible with the QC60 breaker?
This breaker is designed exclusively for use in classic Zinsco and Sylvania load centers that accept QC or thick series plug-in circuit breakers.
How much panel space does the QC60 require?
As a thick series 2-pole breaker, it requires two 0.75-inch spaces, taking up a total of 1.5 inches of space on the panel bus.
Is the Zinsco QC60 suitable for HVAC applications?
Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires a 60A 240V circuit.
Does the QC60 require any special mounting hardware or adapter kits?
No, this breaker features a direct plug-on connection that installs seamlessly into compatible Zinsco load centers without the need for adapter hardware.
Why do electricians often recommend replacing original Zinsco panels?
Original Zinsco equipment is obsolete and has been associated with reliability and safety concerns over time, such as breakers failing to trip or poor busbar connections. When possible, upgrading the entire load center to a modern system is recommended by many professionals.
Does this breaker provide common trip functionality?
Yes, the QC60 features an internal common trip mechanism. If one pole experiences an overload or short circuit, both poles will trip simultaneously to safely disconnect power to the 240V circuit.
