700-CF400D | Allen-Bradley MCS-CF IEC Control Relay, 4 N.O., 110/120V

The 700-CF400D is a 400A magnetic contactor from Allen-Bradley’s 700 series. It is used for controlling and switching high-power AC or DC circuits, typically in motor control, HVAC systems, lighting, and other industrial automation applications. The contactor is designed for heavy-duty applications requiring high switching capacity and reliable operation.

Here are the key specifications for the 700-CF400D magnetic contactor:

• Rated Current: 400A (for AC applications).
• Voltage Rating: Suitable for AC circuits; commonly used for 3-phase AC motors.
• Coil Control Voltage: The contactor coil operates with various voltages, typically AC voltages (e.g., 120V, 240V, 480V) depending on the control circuit configuration.
• Number of Poles: 3-pole contactor for controlling three-phase circuits.
• Application: Used for motor control, lighting control, and other automation systems.
• Ambient Temperature Range: Typically rated for -20°C to 50°C (-4°F to 122°F) depending on the environment.

For detailed specifications, refer to the product’s datasheet or user manual.

When selecting a contactor, consider the following:

1. Rated Current: Ensure that the contactor’s current rating (e.g., 400A) is appropriate for the load it will control.
2. Control Voltage: Choose the correct control voltage for your application (e.g., 120V AC, 240V AC, etc.).
3. Number of Poles: For 3-phase circuits, a 3-pole contactor (like the 700-CF400D) is typically required.
4. Load Type: Consider whether the load is resistive (e.g., heating elements) or inductive (e.g., motors), as motors may require a contactor with higher inrush current tolerance.

Consult with the 700-CF400D datasheet and the Allen-Bradley manual for further guidance on selecting the appropriate contactor size for your application.

The 700-CF400D contactor features diagnostic indicators that provide insights into its operational status. These indicators can show:

1. Coil energization: Indicates whether the coil is energized.
2. Contact condition: Indicates whether the contactor is open or closed.

These diagnostic features can be checked visually, and additional information may be provided through auxiliary contacts if they are used in the circuit.

The 700-CF400D contactor is typically used in AC circuits. The voltage rating can vary depending on the coil control voltage used to energize the contactor coil. It is commonly available for use with 120V AC, 240V AC, and 480V AC control voltages. The power contacts are designed for controlling higher voltage circuits, typically used for 3-phase AC motors.
