GE TEY220 - 20 A, 480 V, 2-Pole Bolt-On Circuit Breaker | AmpState

GE TEY220 is a 20A, 480V, 2-pole bolt-on molded case circuit breaker engineered for dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Built to endure demanding environments, it delivers consistent protection when it matters most in residential, commercial, and light industrial applications.

Key advantages of the TEY220 include a secure bolt-on mounting that creates a rigid, vibration-resistant bus connection—minimizing movement that can loosen connections over time. Paired with a thermal-magnetic trip unit, this breaker delivers stable, repeatable protection: the thermal element handles normal overloads with precision, while the magnetic element provides instantaneous response to high-energy faults, helping to reduce damage and downtime.

Designed for seamless compatibility, the TEY220 works with matching GE OEM loadcenters and other compatible panelboards, making retrofits and replacements straightforward and reliable. This isn’t just a drop-in part—it’s a proven component built to integrate with your existing electrical infrastructure without sacrificing performance or safety.
