## Product Overview: Allen-Bradley 700-F400A1

The 700-F400A1 is a high-performance, IEC-rated industrial relay from Rockwell Automation’s Allen-Bradley line. It is part of the 700-F series of miniature contactor relays, designed for heavy-duty switching in space-constrained control panels.

### Technical Specifications (Product Parameters)

The “400A1” suffix specifically defines the contact configuration and coil voltage:

### Key Product Advantages

• Space-Saving Design: Its miniature footprint allows for high-density installation in control cabinets where space is at a premium.

• High Reliability: Built for millions of mechanical operations, ensuring longevity in demanding industrial environments.

• Modular Flexibility: Supports front-mounted auxiliary contact blocks if additional circuits are required.

• Bifurcated Contacts: The design ensures high contact reliability even at low-level signals.

• Ease of Installation: Features clear terminal markings and a snap-on DIN rail mechanism.

### Safety and Operational Precautions

1. Voltage Verification: Always ensure the supply voltage matches the 120V AC coil rating. Applying DC voltage or incorrect AC levels will damage the coil.

2. Load Limits: Do not exceed the 10A thermal current rating. For high-inductive motor loads, ensure the relay is derated according to the AC-3/AC-15 charts.

3. Environment: Avoid installation in environments with excessive conductive dust or corrosive gases without a secondary protective enclosure (IP20 rated).

4. Wiring: Ensure all screw terminals are torqued to specification to prevent arcing and overheating.

### Common Product Applications

• Control Logic: Used in complex interlocking logic for manufacturing assembly lines.

• Motor Starter Control: Acting as a pilot relay to trigger larger contactors for high-horsepower motors.

• Lighting Systems: Switching industrial lighting circuits.

• HVAC Systems: Controlling fans, dampers, and small pumps.

• Interface Signaling: Isolating PLC (Programmable Logic Controller) outputs from field loads.
