Allen-Bradley 800T-XA4 Shallow Contact Block 2NC

The Allen-Bradley 800T-XA4 is a shallow 30 mm contact block that mounts to an Allen-Bradley 800T pushbutton to provide two normally closed contacts (2NC), expanding the available circuit paths without adding a separate switch housing. As part of the 800T/H accessory family, the XA4 preserves a compact panel footprint and uses screw attachment for secure, vibration-resistant mounting in demanding industrial environments, while its shallow profile helps minimize enclosure depth. The two NC contacts enable two independent circuits within a single 30 mm control station, allowing straightforward stop/interlock or basic interconnection in control logic as part of a compact operator assembly. Designed specifically for 800T series operators, the XA4 integrates with existing 800T assemblies to tailor electrical configurations, supports a space-efficient control panel layout, and preserves the modular simplicity that makes 30 mm pushbutton systems a common choice in automation. In typical panel builds, engineers pair the 800T-XA4 with the corresponding 800T pushbutton to achieve reliable, compact operator assemblies that meet standard 30 mm control station layouts.
