The Eaton JT3100T thermal-magnetic circuit breaker is a 100-amp overcurrent device that uses both thermal and magnetic trip mechanisms to interrupt current during overloads or short circuits. The JT3100T designation places it in the Cutler-Hammer thermal-magnetic line, now part of Eaton's breaker family. It is designed for installation in electrical panels and distribution enclosures to protect circuits with a 100 A rating.
