Schneider Electric ZB5AL3 Push-button Switch 22mm Momentary Green

Product Description

The SCHNEIDER ELECTRIC ZB5AL3 is a 22 mm momentary push-button switch operator designed for industrial control panel applications. This nonilluminated, extended straight-profile button features a round green plastic actuator and mounts through a standard 22 mm panel cutout. Rated NEMA 4X and NEMA 13, it is built for wet, corrosive, and washdown environments. The momentary action returns to the off position when released, making it appropriate for start, jog, or signal functions in control circuits. Licensed electricians and panel builders are the primary installers of this component.

The ZB5AL3 is suited for industrial and commercial control panels where a standard 22 mm operator head is required. Its NEMA 4X rating makes it appropriate for food processing, water treatment, and outdoor enclosure applications where moisture and corrosion resistance are priorities. The green color convention is widely used for start or run functions in machine control wiring. This operator head is part of the Harmony XB5 push-button family and is designed to mate with compatible contact blocks and mounting collars in that system.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize and lock out the control panel before removing or installing any push-button component. The operator head requires a compatible contact block and mounting collar for a complete assembly. Verify the panel cutout diameter and enclosure rating before installation to maintain the NEMA 4X seal integrity.
