GE TEY380 - 80 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The GE TEY380 is a rugged 3-pole bolt-on molded case circuit breaker engineered for dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. With an 80 A rating and a 480 V operating voltage, this unit is built to handle the demanding electrical loads found in residential, commercial, and light industrial environments.

Designed for enduring performance, the TEY380 combines a secure bolt-on mounting with a vibration-resistant bus connection, ensuring consistent contact strength and reduced chances of loose connections in environments subject to vibration or movement. The thermal-magnetic trip unit delivers stable, repeatable protection across a wide range of operating temperatures and fault conditions, helping prevent nuisance trips while preserving equipment safety.

Why the TEY380 stands out

• Bolt-on mounting for reliability — A secure mechanical connection minimizes movement and electrical resistance over time, supporting long-term panel performance.
• Thermal-magnetic protection — Combines overload protection (thermal) with instantaneous short-circuit protection (magnetic) for precise tripping behavior.
• OEM-compatible — Designed to be compatible with matching GE OEM load centers and panelboards, streamlining replacement and upgrades.
• Clear electrical fit — 80 A continuous current rating, 480 V voltage rating, and 3 poles to cover three-phase systems commonly used in commercial and light industrial applications.
• Versatile application — Ideal for residential service panels, commercial distribution panels, and light industrial installations requiring reliable protection for branch circuits.

Real-world use cases

• Upgrading or replacing breakers in GE load centers and panelboards where 3-pole, 480 V service is standard, ensuring compatibility and continuity.
• Protecting motor circuits, lighting feeders, or general branch circuits in small-to-medium commercial spaces where stability and reliability are critical.
• Retrofits in retrofitted or renovated facilities that demand robust bolt-on installation to resist vibration and maintain secure connections.

What problems this breaker helps solve

• Preventing nuisance trips due to marginal connections by using a secure bolt-on mounting that resists loosening over time.
• Providing predictable, stable protection for three-phase systems at 480 V, reducing the risk of electrical faults escalating into equipment damage.
• Streamlining maintenance and replacements with OEM-compatible design, minimizing compatibility concerns during upgrades.

Practical tips for installation and operation

• Verify panelboard compatibility with GE OEM load centers before installing to ensure optimal fit and coordinated protection curves.
• Follow standard electrical safety protocols: de-energize the system, use proper torque on mounting hardware, and confirm bus connections are clean and free of debris.
• Use in environments within its 480 V rating and ensure the connected conductors and accessories are rated appropriately for voltage and amperage.
• Keep spare TEY380 breakers on hand for proactive maintenance in facilities with frequent electrical work or high-load demands.

Choosing the GE TEY380 means opting for a purpose-built solution that pairs robust mechanical design with precise protective characteristics. If your panelboard or load center requires a reliable 3-pole breaker at 480 V and 80 A, this bolt-on molded case breaker from AmpState delivers durable performance, straightforward installation, and compatibility with GE’s OEM platforms—making it a strong candidate for contemporary electrical installations and dependable upgrades.
