140U-JTD3-D17

The Allen-Bradley 140U-JTD3-D17 circuit breaker is an adjust magnetic and fixed thermal circuit breaker that employs two different current detection mechanisms that employ temperature sensors and magnets to detect different types of current. The current that the breaker detects is generally the current that, due to its abnormal nature, tends to cause damages to a machine's conduits, motors, and different kinds of equipment. This breaker has been launched to the industrial market by Allen-Bradley/Rockwell Automation. The Allen-Bradley/Rockwell Automation 140U-JTD3-D17 adjustable magnetic and fixed thermal circuit breaker can be attached to motors, conduits, and circuits of industrial equipment. It is recommended to use it under regular operating conditions and to compare each of its specifications with those of the equipment that requires its protection to guarantee safe operations.

The Allen-Bradley/Rockwell Automation 140U-JTD3-D17 adjustable magnetic and fixed thermal circuit breaker operates with a current rating of 2500 Amps, a frequency of 50 Hertz, and an interrupting current rating of 175 Amps with the thermal mechanism and from 875 to 1750 Amps with the magnetic mechanism. The Allen-Bradley/Rockwell Automation 140U-JTD3-D17 adjustable magnetic and fixed thermal circuit breaker uses a voltage rating between 200 and 575 Volts. Depending on the voltage that is applied, the exact interrupting rating of the breaker can vary. The breaker can operate at 100 percent power at an altitude of up to 1000 meters above sea level and an ambient temperature within the range of  0 to 40 degrees Celsius. It can also operate at up to 75 degrees Celsius and 2800 meters above sea level, but the breaker must be derated. The breaker can be mounted in any position as long as it is protected from solid and corrosive particles and it is connected with wiring that is rated at 75 degrees Celsius. Motors and different equipment must be compatible with all the breaker specifications.
