Product Overview

The Allen-Bradley 700-CF310 belongs to the Bulletin 700-CF family of high-reliability IEC control relays. This 4-pole device provides a specialized contact configuration of 3 Normally Open (N.O.) and 1 Normally Closed (N.C.) poles, optimized for complex interlocking and logic-based control circuits. Its compact frame allows for high-density mounting in motor control centers and automation panels where cabinet space remains at a premium. We provide this unit as 100% Brand New and Original, ensuring your industrial machinery benefits from consistent switching performance and an extended electrical service life.

Engineering Advantages

Bifurcated Contact Design: The 700-CF310 incorporates high-reliability contacts that ensure signal continuity even in low-energy logic circuits. This minimizes the risk of dry-circuit failures in PLC input loops.
Space-Saving IEC Profile: The slim width of the 700-CF series enables engineers to maximize rail density. You can mount these relays side-by-side without derating, provided the ambient temperature remains within the specified 60 degree Celsius limit.
Modular Accessory Expansion: This relay supports the front-mounting of auxiliary contact blocks and pneumatic timers. This flexibility allows you to expand the contact count to up to 8 poles without increasing the DIN rail footprint.
Enhanced Coil Suppression Compatibility: The relay housing facilitates the direct snap-on installation of surge suppressors (such as the 100-FSV136 varistor). This integrated approach eliminates the electromagnetic interference (EMI) that often plagues high-speed communication networks in modern automation panels.

FAQs

Q: What does the "310" in the 700-CF310 part number signify?

A: The "310" designates the base contact configuration. The first digit "3" indicates 3 Normally Open (N.O.) poles, while the second digit "1" indicates 1 Normally Closed (N.C.) pole. The final "0" confirms that no additional factory-installed auxiliary contacts are present.

Q: Can I use the 700-CF310 to switch motor loads directly?

A: No. The 700-CF310 is a control relay, not a power contactor. It is rated for a thermal current of 10A (AC-15/DC-13 duty) and is intended for switching contactor coils, solenoids, and pilot lights rather than high-horsepower motors.

Q: Is the coil replaceable on this model?

A: No, the 700-CF series features a sealed housing design. If the coil fails or if you require a different control voltage, you must replace the entire relay unit. For applications requiring replaceable coils, consider the larger Bulletin 700-P or 700-PK series.

Q: How does this relay perform in high-vibration environments?

A: The 700-CF310 features high-tension screw terminals and a secure DIN-rail latching mechanism. These design elements ensure that wires remain seated and the relay remains fixed during the mechanical vibrations common in gantry systems and heavy manufacturing equipment.
