Allen-Bradley 100-A09NZ3 Contactor

The Allen-Bradley 100-A09NZ3 Contactor with 195-FA11 Auxiliary Contact Block is a compact 3-pole electromechanical switch designed for industrial motor control and automation, providing reliable load switching and an auxiliary signaling path through the 195-FA11 block. It uses a 24 VDC coil to switch up to 9 A (AC-3) and includes one normally open and one normally closed auxiliary contact for status indication or interlocking in control circuits. This Bulletin 100-A device supports DIN rail or panel mounting with screw-clamp terminals and operates on 50/60 Hz electrical systems, offering UL Listed, CSA Certified, and IEC 60947-compliant performance for harsh industrial environments. It is commonly employed in motor starters, conveyors, HVAC equipment, packaging machinery, and other process control applications where compact size and easy panel integration matter. For retrofit or replacement, common alternatives include Allen-Bradley 100-C09D10, Schneider Electric LC1D09BD, and Siemens 3RT2015-1BB41 Contactors.
