GE TEY320 - 20 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Introducing the GE TEY320 — a 20A, 480V, 3-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit protection in panelboards and load centers. Built for commercial and light industrial environments, this device provides precise overcurrent and short-circuit protection when it matters most.

• Rigid, vibration-resistant mounting — secure bolt-on installation ensures a solid bus connection, reducing contact wear and arc risk in busy electrical panels.
• Thermal-magnetic trip unit — combines predictable overload protection with fast short-circuit response, delivering stable and repeatable protection performance across varying loads and temperatures.
• OEM-compatible design — engineered to work seamlessly with matching GE OEM load centers and panelboards, simplifying upgrades, replacements, and serviceability.
• Versatile use for today’s installations — ideal for residential, commercial, and light industrial applications that require reliable 3-pole protection on 480V systems.

The TEY320 is a thermal-magnetic molded case circuit breaker purpose-built for branch circuits where reliable protection is non-negotiable. With a 20A rating on a 480V three-phase supply, it guards equipment and wiring from overcurrent conditions, while its robust bolt-on mounting minimizes operational movement and stress on bus bars during normal operation and fault events.
