Allen-Bradley 800T-N2KF4 Selector Switch With Contact Block

Allen-Bradley 800T-N2KF4 is a 30 mm front-mount selector switch from the 800T family, shipped with a matching 800T-XA contact block. The 800T-XA block provides a two-pole contact set: 1 normally open (NO) and 1 normally closed (NC), enabling simple on/off or mode-selection logic in a single compact unit. The contact block is rated to 10 A and supports up to 600 VAC or 600 VDC, making it suitable for controlling relays, interlocks, and small motor starters in standard industrial panels. This combination is designed for use with Bulletin 800T/H operators and mounts behind the operator in a standard 30 mm assembly, with screw-terminal connections for panel wiring. Common applications include selecting between circuits or control modes in industrial automation, machine control, and process equipment, where a single selector switch with a built-in NO/NC path provides clear, dual‑rail signaling without additional devices.
