The Eaton JT3125T is a JT Series molded case circuit breaker used to interrupt fault currents and protect electrical circuits in distribution panels. Historically cataloged as Cutler-Hammer JT3125T, this device reflects Eaton’s legacy JT lineup. In typical commercial and industrial electrical installations, molded case breakers like the JT3125T provide overcurrent protection for branch circuits within panelboards and switchgear.
