GE TEY2100 - 100 A, 480 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Meet the GE TEY2100—a 100 A, 480 V, 2-pole bolt-on molded case circuit breaker built to shield your panelboards and load centers from overcurrent and short-circuit events. Engineered for dependable protection in residential, commercial, and light industrial settings, this GE breaker combines rugged construction with precise, repeatable performance when it matters most.

Why the GE TEY2100 Stands Out

• Secure bolt-on mounting for a rigid, vibration-resistant bus connection that stays tight through equipment operation and environmental vibration.
• Thermal-magnetic trip unit delivers stable, repeatable protection—responding quickly to hard faults while minimizing nuisance trips on normal startup surges.
• OEM-compatible design works with matching GE load centers and panelboards, helping you maintain system integrity and easy serviceability.
• Two-pole, 100 A at 480 V configuration provides robust branch circuit protection suitable for a wide range of panelboard applications.

Use Cases—Where This Breaker Shines

Ideal for protecting feeders and branch circuits in residential service equipment upgrades, commercial distribution panels, and light industrial power centers. The TEY2100 is well-suited for installations where a rigid bus connection and reliable tripping behavior are critical to maintain uptime and safety.

Practical Benefits and How It Helps You

• Reliability in challenging environments: The bolt-on design minimizes movement under vibration, reducing the risk of loose connections that can lead to overheating or arcing over time.
• Predictable protection: The thermal-magnetic trip mechanism balances heat-based protection with magnetic instantaneous response, helping to isolate faults quickly without overreacting to normal electrical transients.
• Seamless installation and maintenance: OEM compatibility means fewer mismatches in panel upgrades or replacements, simplifying stocking, ordering, and service calls.
• Scalable for future needs: With a 100 A rating at 480 V, the TEY2100 accommodates higher-demand branch circuits common in modern panelboards and data-center or workshop environments.

Installation Tips and Best Practices

• Before installation, verify that the panelboard or load center is rated for 480 V and supports two-pole bolt-on breakers of this type.
• Ensure the mounting surfaces are clean and free from debris to maximize the rigidity of the bolt-on connection.
• Use the correct torque specifications for bolt-on connections to maintain a solid bus contact and minimize thermal rise during operation.
• Inspect the surrounding wiring for proper gauge and routing to prevent unintended strain on the breaker terminals.

Who Should Consider the GE TEY2100

Electrical contractors, facilities managers, and maintenance teams looking to upgrade or replace legacy overcurrent protection in GE-compatible panels will appreciate the TEY2100’s combination of robust build, precise protection, and straightforward compatibility.

Why Choose This Over Generic Alternatives

Unlike generic substitutes, the GE TEY2100 is purpose-built for GE OEM panel systems, ensuring reliable fit, documented compatibility, and consistent safety performance. Its thermal-magnetic protection and vibration-resistant bolt-on mounting are tailored to real-world panel environments, helping you reduce troubleshooting time and service calls.

With the GE TEY2100, you’re investing in proven reliability for critical electrical infrastructure—protecting people, equipment, and processes while supporting smooth panel operations now and as your system scales.
