Overview
The Allen-Bradley 140M-C-AFA11 is an internal auxiliary contact module engineered for integration with 140M-C/D/F series motor protection circuit breakers. This front-mounted contact block provides reliable control signaling and status feedback in motor protection and automation systems. Each unit contains one normally open (1 NO) and one normally closed (1 NC) contact, enabling flexible logic configuration for indicator lights, PLC input signaling, and alarm activation.
Key Features
- 1 normally open + 1 normally closed contact configuration (1NO/1NC)
- Front-mounted design for easy installation without additional footprint
- Internal contact block rated for low-voltage control circuits
- Screw terminal connection for secure wiring
- Compliant with UL, CSA, CUL, CE, and CCC standards
- Compact form factor—no additional width required on motor protector
