Allen-Bradley 800T-XD2 NSNBC01 Time Delay Relay

Allen-Bradley 800T-XD2 NSNBC01 is a 30 mm shallow contact block accessory for the Allen-Bradley 800T family of pushbutton operators, delivering a single normally closed (NC) contact. It is designed to mount with standard 30 mm 800T pushbutton assemblies to extend control functionality without replacing the entire switch. The XD2 designation identifies a 1NC configuration, making it suitable for simple interlocks, sequencing, and feedback in industrial control panels. The NSNBC01 variant represents a specific packaging/production code for this XD2 block, ensuring compatibility with the corresponding operator family. Used in conjunction with compatible wiring, this block preserves the compact footprint of the 30 mm pushbutton system while adding an auxiliary contact point for straightforward control logic.
