Description
A drop-in replacement for older Zinsco load centers, the QFL2200 is a 2-pole, 200A unit mount molded case circuit breaker. It features a feed-through connection and delivers standard thermal-magnetic protection with a 10kAIC rating at 120/240VAC. Engineered to maintain existing residential and commercial services, this legacy main breaker mounts into original enclosures. When sourcing modern cross-references, this exact profile is replaced by the Connecticut Electric UBIZ2200.Specifications

Product FAQs
6 answersWhat enclosures are compatible with the QFL2200 circuit breaker?
The QFL2200 is a unit-mount breaker designed specifically for legacy Zinsco load centers and panelboards. It also fits select GTE Sylvania and Challenger enclosures that were manufactured using the original Zinsco design.
What is the modern cross-reference for the Zinsco QFL2200?
The Connecticut Electric UBIZ2200 is a direct, modern replacement for the QFL2200. It matches the physical profile, mounting style, and electrical ratings required for legacy Zinsco panels.
What are the wiring requirements for the QFL2200?
The breaker features a feed-thru connection and includes line and load lugs. The lugs accept either aluminum or copper conductors ranging from 2/0 AWG to 300 kcmil.
Is the QFL2200 typically used as a main or branch breaker?
Due to its 200A capacity and feed-thru construction, the QFL2200 is primarily installed as a main breaker in legacy Zinsco residential and commercial load centers.
How does the thermal-magnetic trip unit function on this breaker?
The QFL2200 uses a fixed thermal-magnetic trip mechanism providing long-time and instantaneous (LI) protection. The thermal component responds to sustained overloads, while the magnetic component trips immediately during short-circuit events.
What should be inspected when installing a replacement Zinsco main breaker?
Because Zinsco panels are legacy equipment, electricians should carefully inspect the enclosure's busbars before installing the QFL2200. Look for any signs of pitting, corrosion, or arcing, which can compromise the connection and safety of the replacement breaker.
