JT3225T - 225Amp Trip Unit

JT3225T - 225Amp Trip Unit

At 225 amps, the Eaton JT3225T has a specific set of identifiers that should line up with the breaker assembly already in place. It is a three-pole thermal-magnetic trip unit from the Series C family, with a T185 trip type, JT circuit breaker designation, and Frame J-K size. If your existing assembly calls for this particular combination of amperage, poles, trip type, breaker type, and frame size, the published specifications make it easier to confirm form, fit, and function before installation. The JT3225T is built to last, with the focus kept on proper compatibility rather than unnecessary replacement changes.

Key Features and Benefits

• 225A amperage rating for compatible breaker assemblies requiring this trip-unit rating.

Where It Works Best

The JT3225T is suited to compatible existing and legacy Eaton Series C molded case circuit breaker assemblies that call for a 225A, three-pole thermal-magnetic trip unit with the T185 trip type, JT breaker designation, and Frame J-K size. It is a practical choice when the goal is to preserve the required electrical and physical configuration of equipment already in service.
