Overview

The ABB TEYF270 (SKU: TEYF270) is a compact, 2-pole, 70-amp bolt-on circuit breaker engineered for grounded 480Y/277 Vac systems. This TEYF series breaker features a space-saving 1-inch wide per pole design, ideal for optimizing panel density. It offers an 18kA interrupting rating at 480/277 Vac, providing reliable protection for industrial and commercial electrical distribution. The integrated bolt-on mounting base accessory makes the TEYF270 suitable for lug-lug connected applications, enhancing its versatility. Key operational features include Quick-make / Quick-break mechanisms for consistent and reliable arc interruption, common trip bars ensuring simultaneous disconnection of all poles during fault conditions, and easily visible trip indication for efficient maintenance and troubleshooting. The TEYF270 is UL listed HACR (Heating, Air Conditioning, Refrigeration) rated, making it suitable for these specific circuit applications. Wire termination for the 70A rating accommodates copper conductors from #4 AWG to 1/0 AWG. Manufactured in the USA, this breaker is compatible with ABB A-Series lighting panelboards and RE/RS panels. Optional accessories such as auxiliary contacts and shunt trips can be factory-installed for customized functionality. The TEYF series offers higher selectivity ratings with upstream devices compared to the TEY series. This breaker is a direct substitute for the TEY series.
