Federal Pacific 20 Amp Circuit Breaker
Federal Pacific 20 amp circuit breakers are part of the Federal Pacific Electric (FPE) Stab-Lok family of circuit breakers used in older residential, commercial, and electrical distribution panels. Electrical Supplies Unlimited (ESU) buys and sells new, used, surplus, obsolete, and hard-to-find Federal Pacific 20 amp circuit breakers for electricians, electrical contractors, facility managers, businesses, and other customers nationwide.
Federal Pacific circuit breakers are commonly identified by the Stab-Lok name. Several different Federal Pacific 20 amp breaker configurations exist, so it is important to identify the exact breaker type and catalog number before attempting to locate a replacement. The original NA20, for example, is a 20 amp, single-pole, 120 volt Stab-Lok circuit breaker.

Federal Pacific 20 Amp Circuit Breaker
ESU maintains access to a wide variety of electrical equipment, including Federal Pacific 20 amp circuit breakers. Depending on availability, we may have new, previously owned, surplus, discontinued, or obsolete Federal Pacific breakers available.
One commonly encountered Federal Pacific breaker is the NA20, a 20 amp single-pole Stab-Lok circuit breaker. The NA20 is a plug-in breaker rated at 120 volts and is designed for compatible Federal Pacific Stab-Lok load centers. Other 20 amp Stab-Lok breakers, including different body styles and configurations, may also be encountered in older electrical equipment.
Federal Pacific breakers can be found in electrical panels that are many years old. Because several Stab-Lok breaker types exist, customers should not select a replacement based solely on the 20 amp rating. The breaker type, catalog number, number of poles, voltage, physical configuration, and panel compatibility should all be verified.
Federal Pacific Stab-Lok equipment also has a significant history of safety concerns involving certain breakers and panels. For that reason, ESU recommends that customers have older Federal Pacific equipment evaluated by a qualified electrician before replacing or installing circuit breakers.
Common Federal Pacific 20 Amp Circuit Breakers
When searching for a Federal Pacific 20 amp breaker, customers may encounter several different descriptions, catalog numbers, and search terms. Common searches include:
- Federal Pacific 20 amp circuit breaker
- Federal Pacific 20 amp breaker
- Federal Pacific Stab-Lok 20 amp breaker
- Federal Pacific NA20 circuit breaker
- Federal Pacific NA20 breaker
- Federal Pacific 20 amp single pole breaker
- FPE 20 amp circuit breaker
- FPE Stab-Lok 20 amp breaker
- Used Federal Pacific 20 amp circuit breaker
- Obsolete Federal Pacific 20 amp breaker

- Hard-to-find Federal Pacific Stab-Lok breaker
The exact catalog number should always be checked before ordering a replacement. Federal Pacific manufactured different breaker styles, and an older panel may require a specific type of Stab-Lok breaker. A breaker with the correct amperage is not necessarily compatible with every Federal Pacific panel.
Federal Pacific 20 Amp 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 Federal Pacific circuit breaker.
- Manufacturer: Federal Pacific Electric (FPE)
- Product family: Stab-Lok
- Common catalog number: NA20
- Amperage: 20 amps
- Poles: 1 pole for NA20
- Voltage: 120 volts
- Interrupting rating: 10 kA for NA20
- Mounting: Plug-in
- Protection: Thermal-magnetic
- Application: Compatible Federal Pacific Stab-Lok load centers
The Federal Pacific NA20 is a commonly encountered 20 amp single-pole Stab-Lok breaker. However, customers looking for a Federal Pacific 20 amp breaker should verify the complete catalog number and electrical panel compatibility rather than relying solely on the amp rating.
Used Federal Pacific 20 Amp Circuit Breakers
A used Federal Pacific 20 amp circuit breaker may be encountered when maintaining an older electrical panel or attempting to match an existing Stab-Lok breaker. Federal Pacific breakers can be difficult to locate through conventional electrical distributors because many original models are 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 Federal Pacific electrical equipment.
Because of the known safety concerns associated with certain Federal Pacific Stab-Lok equipment, ESU recommends having the panel and breaker evaluated by a qualified electrician before installation or replacement. A used breaker should never be installed simply because it physically fits a panel.
Learn more about purchasing previously owned breakers in our guide to used circuit breakers and whether they are safe.
Federal Pacific 20 Amp Replacement Circuit Breakers
When a Federal Pacific breaker needs to be replaced, identifying the original breaker is the best place to start. The information printed on the breaker can help determine the correct replacement.
Look for the Federal Pacific or FPE name, Stab-Lok designation, catalog number, amperage, voltage rating, number of poles, and other markings printed on the breaker. A photograph of the breaker and electrical panel can also be helpful when identifying an older Federal Pacific model.
Modern replacement breakers are also available for some Stab-Lok applications. For example, replacement products are available for certain NA-style and NC-style Federal Pacific panels. However, customers should verify the specific panel and breaker configuration before selecting a replacement.
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 Federal Pacific Breakers
Many Federal Pacific Stab-Lok panels and breakers are found in older electrical systems. Customers maintaining these systems may need a specific breaker configuration that is no longer readily available through conventional electrical distributors.
ESU specializes in helping customers locate obsolete, discontinued, and hard-to-find circuit breakers. This can be particularly valuable when maintaining older commercial buildings, electrical panels, industrial equipment, or other systems where the original breaker needs to be identified or matched.
The original Federal Pacific NA20 is an example of a legacy Stab-Lok breaker that is no longer commercially produced by the original manufacturer. Schneider Electric lists the NA20 as discontinued, with no direct replacement listed.
