Schneider Electric ZB4BA1 Push-button Switch 22mm

Product Description

The SCHNEIDER ELECTRIC ZB4BA1 is a non-illuminated, momentary push-button switch operator designed for industrial control panel applications. It features a flush-style, round white push button mounted through a 22 mm diameter panel hole. The operator body is constructed of metal, providing durability in demanding service environments. As a momentary contact operator, it activates the circuit only while depressed and returns to its default state on release. This component is installed by licensed electricians and industrial control technicians during panel assembly, retrofits, or switch replacement work. It carries UL 508 listing along with CSA, IEC, and multiple international certifications.

The ZB4BA1 is suited for use in industrial control panels, machine operator stations, and process equipment enclosures requiring a standard 22 mm push-button interface. Its NEMA 4X and NEMA 13 ratings make it appropriate for wash-down environments and locations exposed to dust, oil, or non-corrosive coolants. It is a direct operator head component and requires a compatible contact block to complete the switching function.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC requirements and applicable local codes. De-energize and lock out the control panel before removing or installing any push-button operator. Ensure the panel cutout diameter matches the 22 mm mounting requirement before installation. A compatible contact block must be attached separately to complete the circuit switching function.
