100-C30EJ10 | Allen-Bradley MCS-C Contactor, IEC, 3 Poles, 30A, 24VDC

The 100-C30EJ10 is an electromagnetic contactor used for switching electrical circuits, typically in industrial control applications. It is designed to control the operation of motors, lights, heating equipment, or other electrical devices. The contactor works by using an electromagnet to close or open the contacts in the circuit.

The 100-C30EJ10 contactor features:

• 30A rated current at 600V AC.
• 3-pole configuration, typically used for controlling three-phase loads.
• Coil voltage of 110V AC.
• Compact design, suitable for industrial applications where space is limited.
• High reliability and durability, designed to handle frequent switching operations.

To wire the 100-C30EJ10 contactor:

1. Coil wiring: Connect the coil terminals to a 110V AC control power supply.
2. Load wiring: Connect the three-phase load to the three poles of the contactor (L1, L2, L3). The contacts will allow the load to be powered when the coil is energized.
3. Auxiliary contacts: If additional auxiliary contacts (NO or NC) are needed, they can be wired according to your application to provide extra switching functions.
4. Control wiring: Use appropriate control wiring and ensure all connections are secure before applying power to the circuit.

The 100-C30EJ10 contactor is commonly used in:

• Motor control circuits for industrial machinery.
• Lighting control systems for large installations.
• Heating control applications in industrial processes.
• Pump control in HVAC systems or water treatment plants.

The 100-C30EJ10 contactor requires minimal maintenance, but regular checks can ensure longevity:

• Inspect the contactor periodically for wear or signs of electrical arcing.
• Clean any dust or debris from the contacts and coil to ensure proper operation.
• Check the contactor for any loose or damaged wiring and secure connections.
• If the contactor is operating in a harsh environment (e.g., extreme temperatures or humidity), ensure that it is housed in a protective enclosure.
