140M-H8R-D10

The 140M-H8R-D10 circuit breaker is a piece of motor circuit protection equipment that has been designed and manufactured by Allen-Bradley/Rockwell Automation and included in the 140M-H series. This circuit breaker is a molded-case circuit breaker that employs magnets as a protective means. The mechanism of the circuit breaker consists of the detection and stopping of abnormal currents through the use of magnets. This means that magnets receive a current flow, and depending on the quality and conditions of the current, the circuit breaker will react and stop this current from passing to the motor or a group of equipment. Electrical and mechanical operational tests must be performed to ensure that both the Allen-Bradley/Rockwell Automation 140M-H8R-D10 motor circuit protection equipment and the assigned controller are able to operate with the motor and that they can also provide great protection. This circuit breaker can be installed in a cabinet to protect it from physical contact with different particles.

The Allen-Bradley/Rockwell Automation 140M-H8R-D10 circuit breaker has a high breaker capacity of 55 kilowatts at a specific voltage range of 400 to 415 Volts AC at a frequency of 50 Hertz. These ratings are for three-phase powered operations. Its rated operational current has a 100 Amps rating and the breaker's magnets have a current range of 500 to 1500 Amps. Different operation mechanisms such as the branch circuit protection can be executed with the Allen-Bradley/Rockwell Automation 140M-H8R-D10 circuit breaker. This mechanism is commonly used and successful in a variety of applications. This mechanism consists of connecting 2 or more motors to the same branch circuit. The maximum operating temperature for this circuit breaker is 75 degrees Celsius.
