Product Dimensions：

The GE TEY320 is a three-pole, bolt-on molded case circuit breaker rated at 20 amperes. It functions as an automatic safety device designed to protect electrical systems from damage caused by overload and short-circuit conditions. Utilizing a reliable thermal-magnetic trip mechanism, it handles routine operational currents while reacting instantly to dangerous fault currents. The unit features a compact, space-saving design with a standard bolt-on mounting configuration, making it exceptionally secure and stable when installed in compatible panelboards and switchboards. Its internal architecture incorporates quick-make and quick-break mechanisms to minimize contact wear and ensure long operational life.

Product Parameters

The primary technical specifications of the GE TEY320 include a current rating of 20 A and a voltage rating of 277/480 VAC. It features 3 poles and operates on a thermal-magnetic trip function (LI - Long-time and Instantaneous) with a non-interchangeable trip style. The interrupting rating is 14 kAIC at 480Y/277 VAC. It utilizes a bolt-on connection type and measures approximately 5.25 inches in height, 3 inches in width, and 3.06 inches in depth, with an approximate weight of 2 pounds.

Product Advantages

The GE TEY320 offers robust performance due to its high interrupting capacity relative to its compact size, ensuring dependable fault clearance in tight panel spaces. Its bolt-on design provides superior mechanical stability and resistance to vibration compared to plug-in alternatives, making it ideal for rigorous industrial environments. The quick-make/quick-break action reduces arcing and enhances safety during manual or automatic switching operations. Additionally, its high degree of compatibility with standard GE and ABB lighting panels simplifies replacement, inventory management, and system expansion.

Important Considerations (Precautions)

When handling and installing the GE TEY320, strict adherence to safety protocols is mandatory. All installation, maintenance, and inspection procedures must be performed by qualified electricians with the power source completely de-energized to prevent severe shock or arc flash hazards. The installer must verify that the system voltage and available fault current do not exceed the breaker's rated specifications. Proper torque must be applied to the terminal connections to prevent loose wiring, which can cause overheating and potential fire hazards. Furthermore, the breaker should be operated within its specified environmental limits regarding ambient temperature and moisture.

Product Applications

The GE TEY320 is widely deployed across commercial, institutional, and light industrial facilities. It is primarily utilized in lighting distribution panels to protect three-phase lighting circuits, HVAC control feeds, and small motor loads. Common application environments include office buildings, retail spaces, manufacturing plants, schools, and hospitals where reliable branch-circuit and feeder protection is critical for continuous facility operations.
