Overview
The Allen-Bradley 100-C23A10 is a compact 3-pole IEC contactor from Rockwell Automation’s Bulletin 100-C series, engineered for reliable motor control in industrial applications. This unit is rated for 23A at AC-3 duty (squirrel-cage motor starting and stopping) with a 208–240V AC coil and includes 1 normally open (N.O.) auxiliary contact for control circuit feedback and interlocking. The contactor features screw terminals for secure wiring and line-side coil termination, making it suitable for panel mounting on standard 35 mm DIN rail or direct panel installation.
Key Features
- 3-pole main contacts rated 23A AC-3, suitable for motors up to 10 HP at 460V and 5 HP at 230V
- Factory-installed 1 N.O. auxiliary contact for control feedback and interlocking circuits
- 208–240V AC 50/60 Hz coil with line-side coil termination
- Screw terminals (IP20 finger-protected) for safe, secure connectivity
- DIN rail or direct panel mounting for installation flexibility
- Reversible coil terminals allow wiring from either side of the contactor
