The Allen-Bradley 800T-XD3 is a shallow 30 mm contact block in the 800T family that provides a single normally open (1NO) contact to extend the switching capability of 800T push-button and selector switches. As an accessory in the 800T and 800H line, it mounts behind the operator to add one NO contact for control circuits without adding bulk. This 800T-XD3 is designed for 30 mm 800T operators, enabling an additional NO contact on compatible Allen-Bradley equipment.
