Overview

The ABB TEY345 is a 3-pole, 45-ampere thermal magnetic bolt-on circuit breaker designed for grounded 480Y/277 Vac systems. This UL-listed Type TEY/TEYF breaker is rated for Heating, Air Conditioning, and Refrigeration (HACR) applications, as well as High Intensity Discharge (HID) lighting circuits up to 50A, ensuring compliance with critical electrical standards. The TEY345 features a non-interchangeable trip mechanism for enhanced safety and consistent protection. With a short-circuit rating of 14kA at 480/277 Vac, this compact one-inch-per-pole breaker is suitable for installation in ABB A-Series panelboards and other compatible switchgear. The bolt-on mounting base (TEY3B) provides secure attachment for unit mount or lug-lug connected applications. This breaker is ideal for multi-phase systems requiring reliable overload and short-circuit protection for HVAC, industrial lighting, and other critical power distribution needs. Wire range compatibility includes #10-#4 AWG for 45A applications, accommodating both stranded and solid conductors. The thermal magnetic trip mechanism offers robust protection against overloads and short circuits. Manufacturer: ABB - Electrification. SKU: TEY345. UNSPSC Code: 39121601. Country of Origin: US. The TEY family of circuit breakers are one-inch wide per pole, compact, bolt-on circuit breakers for use on grounded 480Y/277 Vac systems. Short circuit ratings at 480/277 Vac for TEY are 14kA. The bolt-on mounting base (TEY3B) makes TEY and TEYF suitable for unit mount / lug-lug connected applications.
