Eaton Cutler-Hammer LT3450T is a Series C thermal-magnetic trip unit designed to provide reliable overcurrent protection for LT-frame circuit breakers in industrial power distribution systems. It features a fixed 450A current rating and a 600V AC voltage rating, housed within a compact, UL-certified unit measuring 8.5 in x 5.7 in x 5.3 in and weighing 2.75 lb. Engineered for compliance with UL standards, this three-pole unit operates reliably across a temperature range of -25°C to 70°C (-13°F to 158°F). Its LI (Long-time and Instantaneous) trip function ensures protection against both sustained overloads and short-circuit faults, making it suitable for a wide range of commercial and industrial panelboard and switchboard applications.
