140U-JD6D3-D22

The product code 140U-JD6D3-D22 is reserved for a circuit breaker from the Allen-Bradley 140U product series. The circuit breaker is designed and manufactured by Allen-Bradley/Rockwell Automation and it is intended for use with combination starter units. The 140U molded case circuit breakers are designed to trip on an inverse-time basis and at 100% to 125% of its continuous current rating. The continuous current rating of the circuit breaker depends on the installed rating plug and this type of circuit breaker has an adjustable instantaneous trip mechanism. The 140U-JD6D3-D22 circuit breaker is a protective device that is made according to the motor criteria and requirements set in standards such as the CSA, UL, NEMA, and CEC and standards. The 140U product series provides circuit breakers with different frame sizes and current ratings in order to meet a wide range of application needs.

The 140U-JD6D3-D22 circuit breaker includes thermal-magnetic/adjustable magnetic trip protection and an IP2X protection class when it is wired. The unit features three poles and a continuous current rating of 220 Amps. The magnetic trip range of the device is between 1250 and 2500 Amps. The 140U-JD6D3-D22 circuit breaker is used with combination starters with a designated NEMA size of 5. The interrupting rating or breaking capacity of this high interrupting capacity unit is 60 to 69 kiloAmps. In addition to that, the current rating of the unit is 100 rr0 Amps. The 140U-JD6D3-D22 circuit breaker supports optional functionalities such as internal control modules, rotary operators, flex cable operators, and molded case switches. Depending on the requirements of an application, the users can choose the right option to enhance the capabilities of the selected circuit breaker.
