Industrial Push Button Operator

The Schneider Electric ZB4BW113 is a 22 mm extended momentary push button designed for industrial control panels and automation equipment. Its all-metal construction suits harsh environments where plastic operators would degrade. The white head provides clear visibility on crowded panels. Operators needing a maintained-action switch or illuminated variant must select a different model.

22 mm Mounting and Momentary Action

The single specification that determines fit is the 22 mm panel cut-out combined with momentary electrical action. The operator returns to its default position immediately when released, making it suitable for jog, start or reset functions. Panels cut to other diameters or circuits requiring a latching mechanism cannot use this part.

IP66 and NEMA 4X Sealing

The metal bezel and head achieve IP66 and NEMA 13, 4X ratings, resisting powerful water jets and dust ingress during wash-down or outdoor exposure. No moving fan or active cooling exists, so acoustic noise is limited to the mechanical click of the contacts. Power draw is defined solely by the contact block installed behind the operator.

Questions about this item

How does the 22 mm mounting size work once the button is installed in a panel?

The 22 mm diameter matches the standard cut-out for industrial control panels, so the operator seats securely with the metal bezel flush against the surface.

What do the NEMA 13 and IP66 ratings actually limit in daily use?

NEMA 13 protects against oil, coolant and water spray indoors, while IP66 adds resistance to powerful water jets and dust ingress from any direction.

What panel thickness and hardware are needed to mount this extended metal operator?

It fits panels up to the standard 6 mm thickness for 22 mm devices and secures with the included metal locking nut — no extra brackets required.
