GE THQL 20 Amp Circuit Breaker
GE THQL 20 amp circuit breakers are commonly used for circuit protection in residential, commercial, and light industrial electrical panels. Electrical Supplies Unlimited (ESU) buys and sells new, used, surplus, obsolete, and hard-to-find GE THQL 20 amp circuit breakers for electricians, electrical contractors, homeowners, facility managers, businesses, and other customers nationwide.
The GE THQL product family is part of the GE Q-Line family of plug-in circuit breakers. THQL breakers are designed for use with compatible GE electrical panels, load centers, and lighting panels. The THQL1120 is a commonly encountered 20 amp, single-pole THQL circuit breaker rated for 120/240 volts with a 10 kA interrupting rating.
GE THQL 20 Amp Circuit Breakers for Sale

GE THQL 20 Amp Circuit Breaker
ESU maintains access to a wide variety of electrical equipment, including GE THQL 20 amp circuit breakers. Depending on availability, we may have new, previously owned, surplus, discontinued, or obsolete GE THQL breakers available.
One of the most common products in this family is the GE THQL1120, a 20 amp single-pole Q-Line circuit breaker. The THQL1120 is a plug-in breaker with a 10 kA interrupting rating and is designed for compatible GE Q-Line electrical equipment.
GE THQL circuit breakers are available in different amperage and pole configurations. Because GE manufactures several different breaker families, it is important to verify that a replacement is specifically designed for the electrical panel or equipment where it will be installed.
A breaker with the correct amperage is not necessarily compatible with every GE electrical panel. Always verify the breaker type, catalog number, voltage, number of poles, interrupting rating, and panel compatibility before selecting a replacement.
Common GE THQL 20 Amp Circuit Breakers
When searching for a GE THQL 20 amp breaker, customers may encounter several different descriptions and search terms. Common searches include:
- GE THQL 20 amp circuit breaker
- GE THQL20 amp breaker
- GE THQL1120 circuit breaker
- GE THQL 20 amp single pole breaker
- GE Q-Line 20 amp circuit breaker
- GE Q-Line THQL 20 amp breaker
- GE THQL 20 amp replacement breaker
- Used GE THQL 20 amp circuit breaker
- GE THQL 20 amp surplus breaker
- Obsolete GE THQL 20 amp breaker
- Discontinued GE THQL circuit breaker
- Hard-to-find GE THQL circuit breaker
The exact catalog number should always be checked before ordering a replacement. Other specifications, including the number of poles, voltage rating, interrupting capacity, mounting configuration, and panel compatibility, can affect whether a particular THQL breaker is appropriate for an application.
GE THQL 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 GE THQL circuit breaker.
- Manufacturer: GE / General Electric
- Product family: Q-Line
- Breaker type: THQL
- Catalog number: THQL1120
- Amperage: 20 amps
- Poles: 1 pole for THQL1120
- Voltage: 120/240 volts AC
- Interrupting rating: 10 kAIC
- Mounting: Plug-in
- Trip type: Standard / non-interchangeable thermal-magnetic
- Frame: Q-Line
- Applications: Compatible GE load centers and lighting panels
The GE THQL1120 is a commonly encountered 20 amp single-pole THQL breaker. However, customers looking for a GE THQL 20 amp breaker should verify the complete catalog number and electrical panel compatibility rather than relying solely on the amp rating.
Used GE THQL 20 Amp Circuit Breakers
A used GE THQL 20 amp circuit breaker can be a practical option when replacing a breaker in an older electrical panel, particularly when the customer needs to match an existing breaker or locate a specific configuration that may not be readily available through conventional electrical distributors.
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 GE electrical equipment.
Used breakers should be properly identified and inspected before installation. The replacement breaker should match the requirements of the electrical panel and application, including the manufacturer, breaker family, amperage, poles, voltage, mounting configuration, interrupting rating, and other applicable specifications.
Learn more about purchasing previously owned breakers in our guide to used circuit breakers and whether they are safe.
GE THQL Replacement Circuit Breakers
When a GE THQL 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 GE name, THQL designation, catalog number, amperage, voltage rating, number of poles, and other markings printed on the breaker. A photograph of the breaker label can also be helpful when trying to identify an older or unusual GE circuit breaker.
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 GE THQL Breakers
Although GE THQL breakers remain widely recognized and used, older electrical systems can sometimes require 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, industrial equipment, electrical panels, load centers, or other systems where the original breaker needs to be matched.
Learn more about finding older electrical equipment through our pages on obsolete circuit breakers, discontinued circuit breakers, and hard-to-find circuit breakers.
