Zinsco 20 Amp Replacement Circuit Breaker
Zinsco 20 amp replacement circuit breakers are used to replace circuit breakers in older Zinsco electrical panels and load centers. Electrical Supplies Unlimited (ESU) buys and sells new, used, surplus, obsolete, and hard-to-find Zinsco 20 amp circuit breakers for electricians, electrical contractors, facility managers, businesses, and other customers nationwide.
Zinsco electrical panels and circuit breakers are commonly found in older residential and commercial buildings. Because original Zinsco breakers are obsolete, customers looking for a Zinsco 20 amp replacement breaker may need to choose between an original obsolete breaker and a newly manufactured replacement designed for the appropriate Zinsco panel and breaker configuration.
Zinsco 20 Amp Replacement Circuit Breakers for Sale
Zinsco 20 Amp Replacement Circuit Breaker
ESU maintains access to a wide variety of electrical equipment, including Zinsco 20 amp replacement circuit breakers. Depending on availability, we may have new replacement breakers, previously owned breakers, surplus breakers, discontinued products, and obsolete original Zinsco circuit breakers available.
One common replacement is a Zinsco Q20 replacement circuit breaker. New replacement products such as the Connecticut Electric UBIZ20 are designed for Zinsco Type Q panels and provide a 20 amp, single-pole configuration. These replacement breakers are plug-in type breakers and are available with a 10,000 AIC rating.
Zinsco 20 amp breakers are available in more than one configuration. A single-pole Q20 breaker is different from a two-pole QC20 breaker or a tandem-style Zinsco breaker. Customers should identify the existing breaker and panel before selecting a replacement.
Because Zinsco electrical equipment is obsolete, it is especially important to verify the condition of the electrical panel and bus bars. Some Zinsco equipment has a history of reliability and safety concerns, and replacing an individual breaker does not correct problems with a damaged or deteriorated panel. A qualified electrician should evaluate older Zinsco equipment when determining whether a breaker replacement or complete panel replacement is appropriate.
Common Zinsco 20 Amp Replacement Circuit Breakers
When searching for a Zinsco 20 amp replacement breaker, customers may encounter several different descriptions, catalog numbers, and configurations. Common searches include:
- Zinsco 20 amp replacement circuit breaker
- Zinsco 20 amp circuit breaker
- Zinsco 20 amp breaker
- Zinsco Q20 circuit breaker
- Zinsco Q20 replacement breaker
- Zinsco Type Q 20 amp breaker
- Zinsco 20 amp single pole breaker
- Zinsco replacement 20 amp breaker
- UBIZ20 Zinsco replacement breaker
- Used Zinsco 20 amp circuit breaker
- Obsolete Zinsco 20 amp breaker
- Discontinued Zinsco circuit breaker
- Hard-to-find Zinsco 20 amp breaker
The exact catalog number and breaker configuration should always be checked before ordering a replacement. Zinsco panels can use different breaker configurations, including Q, QC, and R-style breakers. A breaker with the correct amperage is not necessarily compatible with every Zinsco electrical panel.
Zinsco 20 Amp Replacement Breaker Specifications
The 20 amp rating identifies the breaker's current rating, but it is only one of several specifications that should be considered when identifying a Zinsco replacement circuit breaker.
- Manufacturer: Zinsco / replacement manufacturers vary
- Product family: Zinsco
- Common replacement type: Q20 / UBIZ20
- Amperage: 20 amps
- Poles: 1 pole for Q20 replacement breakers
- Voltage: 120 volts for typical single-pole Q20 replacements
- Interrupting rating: 10,000 AIC for common new Q20 replacement products
- Mounting: Plug-in
- Breaker type: Type Q replacement
- Panel compatibility: Zinsco Type Q load centers and panels where the replacement is approved
A commonly available modern replacement is the UBIZ20, which is manufactured as a replacement for the Zinsco Q20. Current product specifications identify the UBIZ20 as a 1-pole, 20 amp, 120 volt plug-in breaker with a 10,000 AIC rating and ETL listing to UL 489.
Customers should verify the actual breaker and panel configuration before purchasing. Zinsco also used other 20 amp configurations, including two-pole QC20 breakers, which are not interchangeable with a single-pole Q20 breaker.
Used Zinsco 20 Amp Circuit Breakers
A used Zinsco 20 amp circuit breaker may be an option when maintaining an older electrical panel or when a customer needs to match an original breaker that is no longer manufactured.
ESU has more than 40 years of experience buying and selling previously owned electrical equipment. We specialize in used, surplus, obsolete, discontinued, and hard-to-find circuit breakers, including older Zinsco electrical equipment.
Because of the age of many Zinsco panels and the known concerns associated with some Zinsco equipment, the condition of the breaker and panel should be evaluated carefully. A breaker that physically fits an older panel should not automatically be assumed to be an appropriate replacement.
When possible, a new, tested, and safety-agency-listed replacement breaker may be preferable to a used or refurbished breaker. Current Zinsco replacement products are available from manufacturers specifically producing replacement breakers for legacy Zinsco panels.
Learn more about purchasing previously owned breakers in our guide to used circuit breakers and whether they are safe.
Zinsco 20 Amp Replacement Circuit Breakers
When a Zinsco breaker needs to be replaced, identifying the original breaker and electrical panel is the best place to start. The information printed on the breaker can help determine the appropriate replacement.
Look for the Zinsco name, breaker type, catalog number, amperage, voltage rating, number of poles, and other markings printed on the breaker. A photograph of the breaker and the inside of the electrical panel can also be helpful when identifying an older Zinsco model.
Customers should pay particular attention to the breaker body style and connection to the panel bus. Zinsco equipment includes different breaker configurations, and the physical appearance of a replacement breaker can help determine whether it is designed for the particular panel.
Our Circuit Breaker Identification Guide provides additional information about identifying electrical breakers.
You can also review our Circuit Breaker Compatibility Guide before selecting a replacement. Remember that breakers should only be installed in panels and equipment for which they are approved.
Obsolete and Hard-to-Find Zinsco Breakers
Zinsco electrical panels are found in many older buildings, and original Zinsco circuit breakers are no longer manufactured. This can make finding an exact original replacement difficult, particularly when a customer is trying to maintain an older panel rather than replace the entire electrical system.
ESU specializes in helping customers locate obsolete, discontinued, and hard-to-find circuit breakers. This can be particularly valuable when maintaining older residential buildings, commercial properties, electrical panels, industrial equipment, or other systems where the original breaker needs to be identified or matched.
New replacement breakers are also available for certain Zinsco breaker types. For example, the UBIZ20 is manufactured as a replacement for the Zinsco Q20, while other replacement models are available for different Zinsco configurations.
Learn more about finding older electrical equipment through our pages on obsolete circuit breakers, discontinued circuit breakers, and hard-to-find circuit breakers.
