The Connecticut Electric UBIZ0230 is a newly manufactured replacement circuit breaker intended for use in Zinsco circuit breaker panels. It provides a 30-amp rating and is identified as a replacement component for compatible Zinsco equipment. The breaker is listed by Intertek to UL Standard 489 for molded-case circuit breakers in the United States and Canada, with a 10,000 AIC rating.
Quick Overview
This replacement breaker is designed for panel maintenance or repair when an existing compatible Zinsco breaker needs to be replaced. Its primary identifying details are the Connecticut Electric brand, 30-amp rating, Zinsco panel application, and newly manufactured construction. The correct replacement must match the panel and the original breaker’s required electrical configuration.

What Is the Connecticut Electric UBIZ0230?
The UBIZ0230 is a replacement molded-case circuit breaker manufactured by Connecticut Electric for compatible Zinsco panels. Circuit breakers are designed to interrupt electrical current when a circuit experiences conditions such as an overload or short circuit. A replacement breaker must be suitable for the specific panel design and circuit requirements rather than selected by amperage alone.
This model is intended for replacement use, not as a universal breaker for every electrical panel. Zinsco compatibility is an important part of identifying whether it is appropriate. The panel labeling, existing breaker, and electrical documentation should be checked before installation.
Key Product Features
Newly Manufactured Replacement
Connecticut Electric manufactures this breaker new as a replacement component. That distinguishes it from a used or refurbished breaker, although the product information does not provide additional details about the manufacturing materials, internal components, or production process.
30-Amp Rating
The breaker carries a 30-amp rating. This rating should correspond with the circuit design and the requirements of the equipment being protected. Replacing a breaker with a different amperage without evaluating the circuit can create an unsafe condition, so the original installation and applicable electrical requirements should be reviewed by a qualified professional.
Zinsco Panel Compatibility
The UBIZ0230 is specified for use in Zinsco circuit breaker panels. Zinsco panels and breakers can have different physical and electrical configurations, so the panel type and the original breaker should be compared carefully. The model designation alone should not replace a compatibility check.
10,000 AIC Rating
The product has a 10,000 AIC rating. AIC refers to the ampere interrupting capacity, or the amount of fault current a breaker is rated to interrupt under specified conditions. The available product details do not state whether this rating meets the requirements of a particular installation, so the panel’s specifications and local electrical requirements should also be considered.
Intertek ETL Listing to UL Standard 489
The breaker is identified as Intertek ETL Listed to UL Standard 489 for molded-case circuit breakers in the United States and Canada. This provides a stated product listing for the breaker, but it does not by itself confirm that the component is suitable for every Zinsco panel or every circuit application.
Installation and Compatibility Considerations
Electrical panel work involves shock, arc-flash, fire, and equipment-damage hazards. Installation should be performed by a qualified electrician who can identify the panel, confirm that the replacement is suitable, and verify the circuit before work begins. Turning off an individual branch-circuit breaker may not remove all hazards inside a panel.
Before selecting a replacement, compare the following details:
- The manufacturer and type of the electrical panel
- The labeling inside or on the panel enclosure
- The rating and configuration of the breaker being replaced
- The way the existing breaker fits into the panel
- The circuit’s voltage, wiring, and connected equipment requirements
- Any installation instructions or local code requirements that apply
The supplied product details confirm use in Zinsco panels, but they do not provide installation instructions, physical dimensions, terminal details, or a complete compatibility chart. Those points should be confirmed before work is scheduled, particularly when replacing a breaker in an older panel.
How It Differs From Related Replacement Breakers
Connecticut Electric offers other Zinsco replacement breakers with different configurations. For example, the UBIZ230-1 is described as a two-pole 30-amp replacement with a thick-series body and a 10-year warranty. The UBIZ3030 is described as a twin 30/30-amp thin-series breaker containing two one-pole breakers in a 3/4-inch body, with a 120/240 VAC designation and plug-in construction.
These related models should not be treated as interchangeable with the UBIZ0230. Differences in body style, pole arrangement, physical thickness, and circuit configuration can affect whether a breaker fits and operates correctly in a particular panel. The original breaker and panel documentation should be used to select the appropriate model.
Who It May Be Suitable For
The UBIZ0230 may be suitable for a homeowner, electrician, property manager, or maintenance professional who needs a new replacement breaker for a compatible Zinsco panel and circuit. Its 30-amp rating and stated Zinsco application make it most relevant when those requirements match the existing installation.
It may not be appropriate when the panel is from another manufacturer, when the original breaker has a different configuration, or when the circuit requires a rating other than 30 amps. A qualified electrician can assess whether the issue is limited to the breaker or whether the panel, bus connection, wiring, or connected equipment also requires attention.
Questions to Check Before Installation
- Does this breaker fit every Zinsco panel? No. It is specified for use in Zinsco circuit breaker panels, but the exact panel and breaker configuration still need to be confirmed.
- What is the breaker’s current rating? The stated rating is 30 amps.
- What does the 10,000 AIC rating mean? It is the breaker’s stated ampere interrupting capacity under applicable conditions. The installation must also meet the electrical system’s requirements.
- Is the breaker listed for a recognized standard? It is identified as Intertek ETL Listed to UL Standard 489 for molded-case circuit breakers in the United States and Canada.
- Can a homeowner install it without professional help? Electrical panel replacement can present serious hazards. A qualified electrician should handle the work unless the person performing it has the required training and follows all applicable safety and code requirements.

Final Thoughts
The Connecticut Electric UBIZ0230 is a newly manufactured 30-amp replacement circuit breaker for compatible Zinsco circuit breaker panels. Its stated 10,000 AIC rating and Intertek ETL Listing to UL Standard 489 provide important identification details. The most important step before installation is confirming that the breaker’s physical and electrical configuration matches the panel and circuit. When those details are uncertain, evaluation by a qualified electrician is appropriate.
