Where It Works Best

The JT3250T belongs in compatible Eaton Series C molded-case circuit breaker assemblies that call for a 250A, three-pole thermal-magnetic trip unit. It's particularly relevant when maintaining existing or legacy equipment, where the T185 trip type, JT breaker type, and Frame J-K design must remain consistent with the installed assembly.
