700-CF310E Bulletin 700-CF Industrial Control Contactor | Allen-Bradley

Product Overview

The Allen-Bradley 700-CF310E serves as a high-performance IEC control contactor designed for demanding industrial switching and motor control applications. As part of the Bulletin 700-CF family, this unit handles high-frequency switching cycles with precision, serving as the primary interface between low-power control logic and high-power loads. We provide this unit as 100% Brand New and Original, ensuring that the contact surfaces and coil assemblies meet full factory specifications for electrical endurance and mechanical life.

Technical Specifications

Engineering Advantages

• High-Cycle Durability: The 700-CF310E utilizes advanced silver-alloy contacts that resist welding and pitting. This design extends the operational life of the contactor during heavy-duty AC-3 or AC-4 motor starting applications.

• Electronically Controlled Coil: The "E" designation indicates an electronic coil. This circuitry reduces "coil hum," minimizes power consumption during the holding phase, and provides a wider voltage tolerance, preventing contact chatter during brownouts or voltage fluctuations.

• Space-Efficient Geometry: The compact frame allows engineers to pack more control logic into standard enclosures. Its 0.90 lb lightweight construction reduces the mechanical stress on DIN rails in high-vibration environments, such as mobile machinery or stamping presses.

• Modular Auxiliary Expansion: The front-facing design accepts additional auxiliary contact blocks without increasing the unit's width. This allows for complex interlocking logic or status feedback to PLCs while maintaining a slim profile.

FAQs

• What does the "310" in the part number signify?

  The "310" identifies the specific contact arrangement. It consists of 3 normally open (N.O.) main power poles and 1 normally open (N.O.) auxiliary contact. This configuration suits standard 3-phase motor applications requiring a single feedback or latching signal.

• Does this unit arrive in original packaging?

  Yes. We supply the 700-CF310E in 100% brand new, original factory packaging. This guarantees that the unit remains free of dust and oxidation, which can compromise contact conductivity in precision control circuits.

• Can I mount this contactor in any orientation?

  While the 700-CF310E supports various mounting angles, we recommend a vertical orientation on a standard 35mm DIN rail for optimal heat dissipation and mechanical balance of the internal armature.

• Is the coil replaceable on this model?

  The 700-CF series features a modular design; however, for the 700-CF310E, replacing the entire unit is often more cost-effective and ensures that both the mechanical linkages and the electronic coil share the same wear cycle for maximum reliability.
