JT3175T - 175Amp Trip Unit

JT3175T - 175Amp Trip Unit

When you're looking for a JT3175T, the part number is only the beginning of the compatibility check. This Eaton trip unit is rated at 175 amps with three poles, a T185 trip type, and a J-K frame designation. It belongs to the Series C family and is made for the JT circuit breaker type. The JT3175T is built to last, giving you a clearly specified option when the job calls for a form-fit, functional replacement. One important point: this is a thermal-magnetic trip unit accessory, not a complete circuit breaker.

Key Features and Benefits

• 175A rating for equipment that calls for this specific trip-unit amperage.

Material Compliance and Certifications

The JT3175T is UL Listed. The supplied manufacturer information does not provide additional material or environmental compliance designations, so no other certifications or compliance claims should be assumed.

Where It Works Best

The JT3175T is compatible with existing and legacy Eaton Series C equipment where the original setup calls for a 175A, three-pole thermal-magnetic trip unit with the T185 trip type, JT breaker type, and J-K frame designation.

For replacement work, compare more than the amp rating. Check the catalog number, pole count, trip type, frame designation, breaker type, and dimensions against the component being replaced. That gives you a much better picture of whether the JT3175T matches the form, fit, and functional requirements of the existing assembly.
