Overview
The Allen-Bradley 700-N400A1 is a compact, high-reliability 4-pole industrial control relay designed for general-purpose motor control switching applications. Part of the proven Bulletin 700-N series, this relay delivers dependable performance in automation control systems, motor starters, and industrial machinery control assemblies. The relay operates on 110V AC (50Hz) or 120V AC (60Hz) coil voltage with a maximum control voltage rating of 300V AC.
Key Features
- 4 normally open (N.O.) contacts with 10 amp maximum rating
- Electrically held design with manual override capability for safe maintenance operations
- Convertible contact cartridges—easily configured from N.O. to N.C. as application demands change
- Low-profile form factor enables compact panel mounting and integration
- Highly visible red status indication bar for quick visual verification of relay state
- UL 508 and CSA C22.2 No. 14 certified (cULus listed) for North American installations
