140M-C2E-B16 | Allen-Bradley Motor Protection Circuit Breaker, 1.0-1.6 A

The 140M-C2E-B16 is a magnetic motor starter from Schneider Electric’s TeSys range. It is used for controlling and protecting motors in industrial applications. The starter combines a contactor for switching the motor on and off with a thermal overload relay to prevent damage to the motor from excessive current. The 140M-C2E-B16 is rated for a 16A current capacity and is suitable for AC motor control.

Key specifications for the 140M-C2E-B16 motor starter include:

• Rated Current: 16A.
• Voltage Rating: Suitable for AC motors and typically supports voltages from 230V to 480V AC.
• Number of Poles: 3-pole contactor for 3-phase motor control.
• Coil Voltage: Available in multiple coil voltages (e.g., 24V AC, 120V AC, 230V AC).
• Overload Protection: Built-in thermal overload relay for motor protection.
• Applications: Designed for use in HVAC systems, pumps, fans, and other automated machinery.

Always refer to the product datasheet or user manual for detailed specifications.

Wiring the 140M-C2E-B16 motor starter involves the following steps:

1. Coil Connections:

• The control circuit coil terminals (typically A1 and A2) are where the control voltage is applied (e.g., 24V AC, 120V AC).
• The control voltage energizes the coil, causing the contactor to close and start the motor.

2. Power Connections:

• The L1, L2, and L3 terminals are for the incoming power supply.
• The T1, T2, and T3 terminals are used to connect the motor to the contactor.

3. Thermal Overload Relay:

• Adjust the thermal overload relay to the motor’s full-load current to ensure the motor is protected from overheating due to excessive current.

4. Grounding:

• Ensure proper grounding of the motor starter for safety and stability.

Always refer to the wiring diagram provided in the user manual for more detailed terminal locations and connection instructions.

The 140M-C2E-B16 motor starter is designed for use with AC voltage circuits, typically operating in the range of 230V to 480V AC. The control coil voltage may vary based on the specific model (e.g., 24V AC, 120V AC, 230V AC). Always verify the voltage ratings on the motor starter to ensure compatibility with your motor and control circuit.

To reset the 140M-C2E-B16 motor starter after an overload trip:

1. Identify the cause of the overload: Inspect the motor and load for any issues (e.g., excessive load, motor malfunction).
2. Reset the overload relay: After addressing the cause, press the reset button on the thermal overload relay to clear the fault condition.
3. Test the system: Ensure the motor is operating normally and the starter is functioning correctly before restarting the system.
