Schneider Electric ZB4BA0 Push-button Switch 22mm Momentary

Product Description

The SCHNEIDER ELECTRIC ZB4BA0 is a round, non-illuminated push-button switch operator designed for industrial control panel applications. It mounts through a 22 mm panel cutout and operates on a momentary (MO) action, meaning the contact state returns to its default position when the operator is released. The operator body is metal construction, providing durability in demanding environments. It carries a NEMA 4X and NEMA 13 rating, making it suitable for wet, corrosive, and dust-heavy locations. Licensed electricians and industrial control technicians are the primary installers for this type of component.

The ZB4BA0 is used in industrial and commercial control panel assemblies where a momentary pushbutton operator is required. Typical applications include machine control stations, motor starter panels, and process control enclosures. The 22 mm mounting diameter is a widely adopted standard in industrial controls, and this operator is designed to fit into compatible 22 mm legend plates, contact blocks, and body assemblies within the same product family. The non-illuminated design is appropriate where pilot light indication is not required at the operator position.

Installation Notes

Installation of push-button switch operators should be performed by a qualified electrician or industrial controls technician. De-energize and lock out the control panel per NFPA 70E and applicable OSHA procedures before beginning work. The operator is inserted through the front of the panel cutout and secured with the corresponding mounting hardware from the rear. Do not overtighten mounting hardware on the panel face, as this may crack the operator body or distort the panel surface.
