The Eaton Cutler-Hammer part number JT3175T is a thermal-magnetic trip unit optimized for use with Series C circuit breakers. It offers a continuous current capacity of 175 A and operates efficiently within a voltage range of up to 600 VAC. This trip unit consists of three poles, ensuring reliable performance in three-phase applications.
Designed specifically for compatibility with J frame breakers, the JT3175T features an internal mounting style that enhances integration with the circuit breaker. The mounting mechanism is non-interchangeable, indicating that this trip unit is specifically designed for its intended application. An instantaneous trip range of 5 to 10 times the rated current ensures quick disconnection during fault conditions, providing enhanced protection for connected circuits.
Electrical connections are made via a bolt-in style, which allows for secure mounting and effective power transmission. This trip unit functions at system frequencies of 50 or 60 Hz, maintaining compatibility with standard electrical supply systems. Calibrated to operate optimally at an ambient temperature of 40 °C, the JT3175T ensures stability and reliability under specified conditions.
