GE TEYL3080B - 80 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the GE TEYL3080B, an 80A, 480V, 3-pole bolt-on molded case circuit breaker designed to protect your electrical system with precision and reliability. Built for panelboards and load centers, it delivers dependable branch circuit overcurrent and short-circuit protection for residential, commercial, and light industrial applications.

• Secure bolt-on mounting: Provides a rigid, vibration-resistant connection to the bus, helping maintain consistent electrical performance in dynamic environments.
• Thermal-magnetic trip unit: Delivers stable, repeatable protection by combining thermal long-time delay with magnetic instantaneous trip for fast short-circuit response.
• Three-pole design for 480V systems: Suitable for three-phase power distribution commonly found in commercial and light industrial settings.
• OEM-compatible: Designed to fit matching GE OEM load centers and panelboards, ensuring straightforward replacement and system compatibility.
• Versatile application: Ideal for residential distribution panels, commercial electrical rooms, and light industrial installations where reliable overcurrent and fault protection is essential.

Technical snapshot

• Manufacturer: GE
• Part Number: TEYL3080B
• Type: Thermal-magnetic molded case circuit breaker

Why choose this GE breaker? It’s not just about amperage or voltage. The bolt-on design minimizes field adjustment and reduces the risk of loose connections under vibration, while the thermal-magnetic trip unit provides trusted protection across a range of operating temperatures. When a fault occurs, the instantaneous magnetic trip clears the circuit quickly to minimize damage and downtime, while the thermal element accommodates temporary overloads without nuisance tripping.

Practical use cases

• Protecting a three-phase load in a small manufacturing line or commercial office suite
• Safeguarding branch circuits in buildings where 480V three-phase service is present
• Replacement or upgrade in GE OEM panelboards requiring a bolt-on, high-reliability breaker

Installation and maintenance tips

• Ensure panelboard compatibility: use with GE OEM load centers designed for bolt-on molded case breakers.
• Power down safely and follow proper PPE guidelines during installation.
• Verify bus connections for cleanliness and secure torque to maintain vibration resistance.
