This compact breaker measures 2 inches wide (1 inch per pole) and is designed for space-constrained installations, including ABB A-Series and RE/RS panelboards. The TEY2100ST12 features a factory-installed 120-277V AC shunt trip accessory for remote electrical tripping, enabling precise operational control in critical applications such as lighting panelboards, distribution boards, and HVAC systems. Key specifications include a continuous current rating of 100A, a 14kA interrupting rating at 480/277 Vac, and a thermal-magnetic trip mechanism with quick-make/quick-break operation for rapid fault response. The breaker includes a common trip bar to ensure simultaneous disconnection of both poles during faults, a visual trip indicator for immediate fault identification, and compatibility with auxiliary contacts for enhanced monitoring. The TEY2100ST12 is UL/cUL listed (File E-11592) and HACR-rated for heating, air conditioning, and refrigeration applications, making it suitable for environments requiring reliable 480Y/277V power distribution. Designed for bolt-on mounting with the TEY3B or TEY3B125 accessory, the TEY2100ST12 supports lug-lug connections and is non-interchangeable to prevent unauthorized adjustments, ensuring system integrity. Its compact design and compatibility with ABB panelboards make it an ideal choice for facilities prioritizing space efficiency and operational safety. The breaker’s 100A rating and 2-pole configuration provide robust protection for branch circuits in commercial buildings, industrial facilities, and critical infrastructure.
