140U-JD6D3-D12

The 140U-JD6D3-D12 circuit breaker is a thermal-magnetic circuit breaker that is designed and manufactured by Allen-Bradley/Rockwell Automation. This protective industrial component is part of the 140U product group and it offers the crucial functions that are necessary for any secured system. The 140U circuit breakers are available with several different frames and as combination/starter units. The wide range of models ensures that specific application requirements are met and every circuit breaker of this kind is designed to trip at 100% to 125% of their rating for the continuous current. The 140U-JD6D3-D12 circuit breaker is built with a JD frame and it is a specified component for a size 4 NEMA starter unit. The 140U-JD6D3-D12 circuit breaker has three poles and it comes without the internal control modules that are available for some frames.

The interrupting rating or breaking capacity of the circuit breaker unit is 60 to 69 kiloAmps while the continuous current rating is 125 Amps. The 140U-JD6D3-D12 circuit breaker features a thermal-magnetic/adjustable magnetic trip and it has a magnetic trip range of 625 to 1250 Amps. In addition to that, the current rating is 100 Amps. The unit has an output rating of 97 Amps and it includes a nominal output power rating of 60 Horsepower at 460 Volts and 60 to 75 Horsepower at 575 Volts. This component carries the IP2X protection marking when it is wired and it is designed for an operating temperature range of -25 to 60 degrees Celsius (-13 to 140 degrees Fahrenheit). The storage temperature range is -40 to 80 degrees Celsius (-40 to 176 degrees Fahrenheit).
