JDB3175 - 175Amp Circuit Breaker

JDB3175 - 175Amp Circuit Breaker

The JDB3175 gives you several concrete details to work from when matching a circuit breaker to equipment already in service. It is a 175A, three-pole Eaton Series C molded case circuit breaker with a JDB breaker type, J frame, and T186 trip type. Eaton identifies it as a complete breaker, with aluminum line and load terminals included. The JDB3175 is built to last, but the replacement selection still comes down to the basics: make sure the frame, breaker type, trip type, terminals, electrical ratings, and dimensions match the requirements of the existing equipment.

Material Compliance and Certifications

The JDB3175 is UL Listed, providing a manufacturer-confirmed certification that buyers can check when matching the breaker to the requirements of an existing installation. No additional material or environmental compliance information was supplied for this catalog number, so certifications such as RoHS, REACH, CSA, or IEC compliance should not be assumed.

Where It Works Best

The JDB3175 is suited to compatible existing and legacy electrical equipment that specifically calls for a 175A, three-pole Series C JDB circuit breaker with a J frame and T186 trip type. Because this model includes aluminum line and load terminals, the terminal arrangement and materials should also be part of the compatibility check.
