When you need dependable overcurrent protection for 480V systems, the General Electric TEY320ST12 circuit breaker delivers precise, reliable performance. This 20A, 3-Pole, bolt-on device is purpose-built for maintenance, retrofit, and replacement projects where exact specifications matter, providing predictable protection across all three phases.
The bolt-on design enables a fast, secure installation in compatible GE panels, helping minimize downtime during panel upgrades or service work. With a three-pole configuration, it ensures coordinated interruption and protection across all phases of your 480V distribution system, making it an ideal choice for motor drives, line feeders, and industrial control circuits.
Who benefits most from this breaker? Facilities engineers, maintenance technicians, and electrical contractors who manage mid-to-large scale industrial facilities, retrofit projects, or legacy panels that require a precise GE TEY-series compatible part. It’s specifically suited for applications where a bolt-on, 3-Pole, 480V breaker is specified, delivering consistent performance in demanding environments.
Practical usage scenarios include retrofitting aging panels to improve safety margins, replacing worn or defective breakers in 480V networks, and upgrading control circuits where a reliable, high-availability protection device is necessary. Compared to non-bolt-on equivalents, this model emphasizes quick, clean installation with robust attachment to support bus bars and list-rated operation in busy electrical rooms.
Notes: Confirm fit and ratings before ordering. The part number TEY320ST12 is the best reference for compatibility.
