Overview
The Allen-Bradley 100-FA20 is a front-mount auxiliary contact block designed to add extra contact points to Allen-Bradley 100-C, 104-C, 700-CF, and 700S-CF contactors. This two-pole device features two normally open (N.O.) contacts and snap-on mounting for fast installation or removal without tools. With screw terminal connections, the 100-FA20 simplifies adding logic, status, and auxiliary signaling capabilities to existing contactor systems.
