TEY220 panelboard fit: ABB/GE TEY220 is a compact two-pole bolt-on breaker developed for grounded 480Y/277-volt panelboard systems. It can carry lower-voltage ratings too, but the interrupting value changes with system voltage.
TEY220 specifications
-
Catalog number: TEY220
-
Rating: 20A, 2-pole
-
Mounting: TEY bolt-on
-
Trip: Fixed long-time and instantaneous, common trip
-
Interrupting rating: 65kA at 120, 120/240, or 240VAC; 14kA at 277VAC
Why one AIC number is incomplete
The marked voltage-specific interrupting ratings must be applied to the actual system. The breaker is not simply “65kA at 480V,” and its grounded 480Y/277 use must follow the manufacturer limitations.
Before installation
Confirm the full TEY220 marking, panelboard acceptance, system grounding and voltage, available fault current, conductor range, and bolt-on hardware. BreakerSmart's current variant has no SKU recorded, so use the product label—not the storefront SKU field—as the final identifier. Installation should be performed by qualified personnel.
