GE TEB111020WL - 20 A, 120 V, 1-Pole Circuit Breaker | AmpState

Meet the GE TEB111020WL, a compact 20A, 120V, 1-pole molded case circuit breaker designed to protect your electrical system with precision and reliability. Built for dependable branch circuit overcurrent and short-circuit protection, it fits seamlessly into panelboards and load centers where space is at a premium and consistent performance is non-negotiable.

• Space-efficient design: The molded case format minimizes panel depth and frees up valuable space inside residential, commercial, and light industrial panels.
• Thermal-magnetic trip unit: Combines a thermal element for overload protection with a magnetic trip for fast, deterministic short-circuit clearing—delivering stable, repeatable protection under a wide range of fault conditions.
• 1-pole, 20A, 120V operation: Ideal for individual branch circuits requiring reliable, localized protection without adding extra poles or complexity.
• OEM compatibility: Engineered to pair with matching GE load centers and panelboards, ensuring straightforward installation and coordinated performance within existing systems.
• Versatile application: Suitable for residential, commercial, and light industrial environments where dependable overcurrent and short-circuit protection is essential.

Technical snapshot

• Manufacturer: GE
• Part Number: TEB111020WL
• Type: Thermal-magnetic molded case circuit breaker
• Amperage Rating: 20A
• Voltage Rating: 120V
• Number of Poles: 1

Why this breaker makes sense for your panel upgrades or new installs:

• Precise protection where it matters—the dual-action trip mechanism reduces nuisance trips while ensuring fast response to dangerous faults.
• Scalable reliability—a single-pole design keeps wiring simple and maintains consistent protection across multiple circuits in the same panel.
• Long-term compatibility—paired with GE load centers and panelboards, it supports streamlined maintenance, easier part sourcing, and predictable performance over time.

Use cases and scenarios:

• Replacing a worn or outdated breaker on a GE panelboard without reconfiguring the entire electrical layout
• Adding dependable branch circuit protection for a dedicated appliance or lighting circuit in residential spaces
• Upgrading a small commercial or light industrial panel where space is limited but protection must remain robust

Key considerations to maximize performance:

• Ensure the panelboard or load center is designed to accept a GE TEB series 1-pole breaker for optimal fit and coordination
• Match the amperage rating and voltage to the specific circuit requirements to prevent nuisance trips and ensure safe operation
• Follow standard electrical safety practices during installation, and power down the system before replacing any breakers
