Welcome to our curated selection of Connecticut Electric breakers, specializing in newly manufactured replacements for hard-to-find Zinsco and Federal Pacific panels. These breakers are essential for homeowners and electricians maintaining or upgrading vintage electrical systems without the need for costly panel replacements, offering peace of mind through reliable performance and safety compliance.
Why Connecticut Electric Stands Out in Circuit Breakers
Connecticut Electric has built a strong reputation for producing high-quality, compatible replacement breakers that match the exact specifications of discontinued brands like Zinsco and Federal Pacific Electric Stab-Lok. Their products are engineered for seamless integration into older load centers, addressing a common pain point for property owners dealing with obsolete equipment. What sets them apart is their commitment to UL listing, precise dimensional matching (thin or thick series), and robust construction that prevents common issues like overheating or nuisance tripping.
When shopping in the broader Electrical category, these breakers shine for their value in restoration projects. Unlike generic alternatives, Connecticut Electric ensures breakers fit perfectly, maintaining the panel's original bus bar compatibility while meeting modern safety standards.
Key Features to Consider When Buying
Selecting the right breaker involves evaluating amperage, pole configuration, voltage, and series type. Here's what to prioritize:
- Amperage and Poles: From 15A single-pole to 100A double-pole, choose based on your circuit's load requirements.
- Series Type: Thin series for compact spaces in Zinsco panels; thick series for heavier-duty Stab-Lok applications.
- Voltage Rating: Most handle 240V, ideal for appliances and main feeds.
- Compatibility: Verified replacements for specific obsolete models like RC3830 or NA2100.
- Build Quality: Gray thermoplastic housings resist environmental stress, with silver-tungsten contacts for longevity.
These features make Connecticut Electric breakers a go-to for DIY enthusiasts and pros alike, especially in homes built before the 1980s.
Comparing Top Connecticut Electric Models
Our category features four standout products tailored to different needs:
- The UBIZ0230 serves as a direct replacement for Zinsco RC3830, a two-pole 30A thin series breaker rated at 240V. Perfect for branch circuits powering dryers or ranges.
- The UBIZ0220 mirrors the Zinsco RC3820, offering two-pole 20A thin series protection for lighter loads like water heaters.
- For Federal Pacific needs, the UBIF2100N replaces NA2100 with a two-pole 100A thick series design, suited for main or subpanel feeds.
- The UBIF015N is a one-pole 15A thin series swap for NC115, ideal for standard lighting and outlet circuits.
Choose UBIZ series for Zinsco panels if space is tight; opt for UBIF in Stab-Lok setups. The 100A model excels in high-demand scenarios, while lower-amp options handle everyday use. All provide thermal-magnetic trip protection for overload and short-circuit safety.

Common Use Cases and Buying Tips
These breakers are invaluable for electrical repairs in older homes, apartments, or commercial retrofits. Use the 20A or 30A Zinsco replacements for kitchen or laundry circuits; the 15A single-pole for bedrooms; and the 100A for service entrance upgrades. Always verify panel type via the manufacturer's label before purchase.
Part of our extensive Breakers, Load Centers & Fuses selection, these fit into larger Tools & Home Improvement projects. Pro tip: Pair with a voltage tester and torque wrench for safe installation—consult a licensed electrician for complex jobs.
Frequently Asked Questions
Are Connecticut Electric breakers UL-listed and safe for older panels?
Yes, all models are UL-listed and tested for compatibility, providing reliable protection equivalent to originals while exceeding many safety benchmarks.
How do I choose between thin and thick series breakers?
Thin series (like UBIZ0220 or UBIF015N) fit compact Zinsco or Stab-Lok slots; thick series (UBIF2100N) for larger Federal Pacific bus bars—match your panel's specs.
Connecticut Electric vs. other brands like Siemens?
Connecticut Electric excels in legacy replacements where Siemens focuses on new QO or QP panels; use them complementarily based on your system's age.
What is the warranty on these breakers?
They typically come with a limited lifetime warranty against defects, backed by strong customer support for compatibility queries.
Can I install these myself?
Qualified DIYers can for simple swaps, but local codes often require professional installation—always de-energize the panel first.
