Overview

The ABB TEY125 (SKU: TEY125) is a single-pole (1P), 25-ampere Molded Case Circuit Breaker (MCCB) engineered for grounded 480Y/277 Vac systems. Designed with a compact 1-inch-wide-per-pole footprint, the TEY125 is optimized for space-constrained panelboard installations, including ABB A-Series and RE/RS panelboards. This breaker features a Quick-make/Quick-break mechanism for reliable operation and includes a common trip bar to ensure consistent tripping across all poles in multi-pole configurations. The TEY125 supports solid or stranded wire connections for 14-10 AWG conductors and is UL listed for Heating, Air Conditioning, and Refrigeration (HACR) applications, as well as High-Intensity Discharge (HID) lighting systems up to 50A. Its 14kAIC short circuit rating at 480/277 Vac makes it suitable for branch circuit protection in lighting panelboards, HVAC systems, and industrial control panels. The TEY125 is bolt-on compatible with the TEY3B mounting base accessory, enabling lug-lug connected applications for versatile deployment in commercial and industrial settings. Optional accessories such as auxiliary contacts (TEYXASL/TEYXASR) and shunt trips (TEYXS1-TEYXS9) are available to expand functionality for integration into complex control systems. The TEY125 is a direct substitute for TEYF and TEYL breakers in certain applications and is manufactured in the USA.
