100-C AUX CONTACT BLOCK FRONT MOUNTING 4NO

The ALLEN-BRADLEY 100-FA40 is an auxiliary contact block that provides four normally open (4 NO) contacts for front mounting on 100-C contactors. Designed for front mounting with screw terminals, it attaches directly to 100-C contactors to add auxiliary switching points for control circuits. The four NO contacts allow simple expansion of control functions such as signaling, interlocking, or feedback to PLC and relay inputs. Ideal for electricians and control panel builders who need a compact, front-mounted auxiliary contact block to integrate additional switching into existing 100-C contactor installations.
