Overview
The Allen-Bradley 700-N510A1 /C is a NEMA Low Profile industrial control relay engineered for demanding factory automation and machine control applications. Rated at 10A contact capacity and 300VAC nominal voltage, this relay delivers the proven reliability and longevity required in continuous-duty industrial environments.
Key Features
- Electrically held relay design with manual override capability for safe, hands-on intervention
- Manually visible red bar status indication for instant operational feedback
- Convertible contact cartridges—field-swappable from Normally Open (N.O.) to Normally Closed (N.C.) and vice versa
- NEMA A300 AC rated contacts rated for up to 300VAC
- Robust mechanically linked contact system for high reliability and long contact life
- Compatible with DIN rail or standard control panel mounting
Technical Specifications
- Contact Rating: 10A at 300VAC (NEMA A300)
- Coil Voltage Range: 24–250V AC available
- Contact Configuration: 4–8 poles available (convertible)
- Terminal Type: Screw-terminal connection
- Contact Life: Extended due to mechanically linked design
- Electrical Certifications: UL 508, CSA C22.2 No. 14, cULus Listed (File No. E14840)
- Standards Compliance: EN/IEC 60947-1, EN/IEC 60947-5-1
Typical Applications
- Motor start/stop and reversing circuits in manufacturing equipment
- Machinery interlocking and safety hold circuits
- Process valve and pump control in batch operations
- Industrial automation and control panel switching
- Replacement or retrofit of legacy relay-based control systems
Compatibility & Replacements
The 700-N510A1 /C is part of Allen-Bradley’s Bulletin 700 industrial relay family, which includes the 700-P (NEMA heavy-duty), 700-CF (IEC control), and 700-R (latching) variants. Contact cartridges are interchangeable within the 700-N platform, enabling field configuration for different contact arrangements without replacing the entire relay. Check coil voltage and pole count when cross-referencing similar NEMA relays from competing manufacturers. Always verify application voltage and contact load ratings before installation.
