140M-H8P-C70

The 140M-H8P-C70 circuit breaker is a molded-case circuit breaker that has been designed and manufactured by Allen-Bradley. This circuit breaker has been designed with the specifications of Frame H from the Allen-Bradley 140M series of motor protection circuit breakers. This specific circuit breaker provides short-circuit protection and it requires a different device that provides overload protection to work along with it to protect the host machine as well as possible. The Allen-Bradley 140M-H8P-C70 molded-case circuit breaker has a rated operational current of 70 Amps and a magnetic trip current that goes from 210 to 770 Amps. This circuit breaker can be used with both single and 3-phase motors. It has an output rating of 30 kilowatts. This circuit breaker can operate with 100% efficiency if it is applied and installed properly. The installation steps for this circuit breaker are not complex.

The Allen-Bradley 140M-H8P-C70 molded-case circuit breaker provides disconnection for the motor branch circuit, short-circuit protection, branch-circuit protection, overload protection, and switching functions. This circuit breaker can operate at a maximum temperature of 75 degrees Celsius, It is recommended to use aluminum and copper wirings rated at up to 75 degrees Celsius that can handle frequent operation at the highest specified temperature. It is recommended to install the breaker in a cabinet and locate it in a strategic place so it can fulfill its purpose correctly. Before making the final selection of the Allen-Bradley 140M-H8P-C70 molded-case circuit breaker, the motor that will host it needs to be examined to guarantee that both devices are compatible and that they can operate without inconveniences. A protective device like a circuit breaker is necessary for industrial motors since it can help reduce the risks of accidents and faults that are caused by an irregular current.
