Overview
The Allen-Bradley 100-F /B auxiliary contact block is a compact snap-on front-mount accessory designed for integration with Allen-Bradley 100-C series contactors. With a current rating of 10 amps and voltage rating of 600V AC, this auxiliary contact block expands the logic capabilities of standard contactors by adding extra contacts for signal monitoring and control interlocking. The Series B construction delivers durability suitable for industrial automation, motor control, and process control applications.
