Product Description
GE’s TEY320 is a compact, one-inch-per-pole, bolt-on lighting panel circuit breaker designed for grounded 480Y/277 VAC systems. This 3‑pole, 20 A thermal‑magnetic device features LI trip (long‑time and instantaneous), a non‑interchangeable trip unit, and common trip across poles for coordinated protection. It provides 14 kA interrupting rating at 277/480 VAC and supports reverse feed where permitted. The breaker includes integral Cu/Al load lugs and a quick‑make/quick‑break mechanism with clear trip indication. Rated for 40 °C ambient, the TEY320 fits TEY frame/Q‑Line applications and is suitable for industrial distribution panels requiring a bolt‑on connection. Typical wiring accommodates 14–10 AWG copper or aluminum conductors. Accessories such as auxiliary contacts and shunt trip are available on select TEY variants, though this catalog number is supplied as a standard LI thermal‑magnetic unit. Dimensions are approximately 5‑1/4 in H x 3 in W x 3‑1/16 in D, enabling straightforward installation in compatible GE lighting panels.
