GE TEY280 - 80 A, 480 V, 2-Pole Bolt-On Circuit Breaker | AmpState

The GE TEY280 is a rugged 80A, 480V, 2-pole bolt-on molded case circuit breaker designed to deliver reliable branch circuit protection in panelboards and load centers. Built for demanding environments, this unit pairs precise protection with a secure mounting method that stands up to vibration and routine maintenance.

Why this breaker stands out

• Secure bolt-on mounting provides a rigid, vibration-resistant connection to the bus—reducing the risk of loose contacts and intermittent trips in dynamic electrical environments.
• Thermal-magnetic trip unit delivers stable, repeatable protection across varying temperatures and load conditions. The thermal element handles gradual overloads while the magnetic element responds instantly to short-circuits, helping to minimize equipment damage and downtime.
• OEM-compatible design is intended to work with matching GE OEM load centers and panelboards, simplifying replacement and retrofits without sacrificing performance or safety.
• Versatile application suited for residential, commercial, and light industrial settings—perfect for protecting branch circuits in HVAC, lighting, receptacle panels, and control enclosures.

Ideal use cases

Choose the TEY280 when you need dependable protection for 480V branch circuits in panelboards or load centers. It’s an excellent fit for:

• New installations in commercial spaces—protecting power distribution for lighting, outlets, and equipment
• Retrofits in older panels where a bolt-on, vibration-resistant connection is beneficial
• Light industrial applications where reliability under variable loads is critical, such as processing rooms or machine enclosures
• HVAC and critical mechanical systems that benefit from a robust, fast-acting protection solution

How it helps you run safer, longer-lasting electrical systems

By combining a secure mounting method with a thermal-magnetic trip mechanism, the TEY280 minimizes nuisance trips while still delivering rapid intervention when a fault occurs. That means fewer unplanned outages, reduced wear on downstream equipment, and easier maintenance in busy panel environments.

Practical guidance for selection and installation

For optimal performance, pair this 80A, 480V, 2-pole breaker with GE TEY-series-compatible panelboards or OEM panels designed for bolt-on molded case breakers. Ensure the protected circuit and connected equipment align with the 80A rating and the 480V electrical system to maintain safety margins and code compliance. This unit is purpose-built to protect branch circuits against overcurrent and short-circuit conditions, helping you keep critical loads energized with minimal disruption.
