The Allen-Bradley 140M-D8E-C10 Combination Starter 100-C12EJ10 is a versatile and reliable electrical component designed for use in various industrial applications where both overload protection and motor starting functions are required. This starter offers 24VDC coil operation and is suitable for use with motors that have a starting current up to 125 amperes and a rated motor horsepower up to 50 horsepower.
The 140M-D8E-C10 Combination Starter comes with an integrated overload relay, which provides protection against overcurrent conditions. The overload relay is set to trip when the motor current exceeds a predetermined value, thus preventing damage to the motor or other electrical components in the system. The starter also features a shunt trip coil for manual tripping, which can be used in case of overload conditions that cannot be cleared automatically.
The motor starting function of the 140M-D8E-C10 Combination Starter is accomplished through its contactor and overload relay. The contactor is rated for 100 amperes at 24VDC and 600 volts AC, and it provides the electrical connection between the power source and the motor during starting. The contactor is designed to close when the start button is pressed, allowing current to flow to the motor. Once the motor has reached its desired speed, the running contactor is closed, and the contactor is held in the closed position by the motor current.
The Allen-Bradley 140M-D8E-C10 Combination Starter is also equipped with a thermostat overload option, which provides additional protection against overheating. The thermostat overload is located in the motor winding and monitors the motor temperature. If the motor temperature exceeds a predetermined value, the overload relay trips, opening the contactor and stopping the motor.
The 140M-D8E-C10 Combination Starter is designed for easy installation and maintenance. It comes with a removable terminal block that allows for easy wiring connections, and it also features a clear cover for easy viewing of the contactor and overload relay status indicators.
Overall, the Allen-Bradley 140M-D8E-C10 Combination Starter 100-C12EJ10 is a robust and versatile electrical component that offers both overload protection and motor starting functions in a single package. Its 24VDC coil operation, integrated overload relay, and optional thermostat overload make it an ideal choice for a wide range of industrial applications.
