Emergency Stop Push Button 22 mm

The Schneider Electric XB4BT845 is a non-illuminated red emergency stop push button built for industrial control panels. It provides a 1NO/1NC contact configuration for safety circuits in manufacturing and automation environments. The 22 mm mounting diameter fits standard panel cut-outs. This component is intended for machine builders and maintenance engineers who need a reliable safety disconnect.

Panel Mounting and Contact Flexibility

The operator uses a chromium-plated metal bezel that secures to a fully metal mounting collar with a single screw. This snap-fit head and body system allows fast installation without periodic retightening. The 1NO/1NC contacts support both low-load signalling and higher-power switching, giving designers freedom to wire the button into diverse safety architectures. Shake-proof connection screws keep terminations secure under vibration.

Sustained Operation in Harsh Conditions

The modular construction resists high-pressure cleaning, dust ingress and extreme temperatures typical of automotive, textile and timber production lines. Contacts maintain consistent actuation force over extended duty cycles without degradation. The robust metal collar and snap-lock mechanism prevent loosening during continuous vibration, ensuring the emergency function remains dependable throughout the equipment service life.

Questions about this item

How long before the 1NO/1NC contacts wear out on this emergency stop?

The contacts are built for industrial duty cycles; mechanical life is rated for millions of operations under normal conditions.

Does the 22 mm chrome-plated metal body get hot or noisy when left engaged all shift?

No moving parts generate heat or sound once the button is latched; the metal collar simply dissipates ambient temperature.

What mounting hardware must I already have to install this XB4BT845?

A standard 22 mm panel cut-out and the matching Harmony XB4 metal mounting collar are required for secure snap-fit installation.
