Allen-Bradley 800T-XA Auxiliary Contact Block

The Allen-Bradley 800T-XA is a 30 mm shallow auxiliary contact block designed to mount on 800T/H pushbuttons, adding a second circuit with a single normally open (NO) and one normally closed (NC) contact. With screw attachment for secure mounting to 30 mm operator controls, this accessory is part of the 800T family and provides an extra contact set without replacing the primary device. It is rated for up to 600 V AC or DC and can carry up to 10 A, making it suitable for signaling, interlocking, or auxiliary control in standard machine-control panels. The 800T-XA's 1 NO / 1 NC configuration supports simple signaling or safety-related interlocks in the same compact footprint as the original pushbutton, enabling compact control circuits in space-constrained panels. Supplied as a single piece, the 800T-XA is a shallow block designed for quick field installation and straightforward integration with existing 800T controls. Active in many industrial applications, it pairs with pushbuttons and other 800T/H components to expand logic options while maintaining the original actuator aesthetics and fit.
