Overview
The Allen-Bradley 100-SA02 is a side-mounted auxiliary contact block designed for integration with IEC-standard 100-C, 104-C, 700-CF, and 700S-CF contactors and control relays. This 2-pole block provides two normally closed (2NC) contacts without sequence numbering designations, making it ideal for logic, status, and monitoring circuits in industrial automation and control applications.
Key Features
- 2 normally closed (NC) contacts for reliable logic and safety signal monitoring
- Side-mount configuration for compact footprint on existing contactors
- Screw terminals for secure, field-serviceable wire connections
- IEC-compliant design compatible with Rockwell Automation 100-series products
- Box of 10 units—ideal for stock replenishment and system redundancy

Compatibility & Replacements
The 100-SA02 is a direct-fit accessory for Rockwell Automation’s IEC product line and serves as a standard replacement or spare block for 100-C series contactors. It pairs with additional auxiliary contact options such as the 100-SA01 (1NC configuration) for flexible logic design. Always verify contactor model compatibility before installation. Rockwell Automation’s technical documentation (reference 100-TD013) provides detailed application guidance.
