Schneider Electric ZB5AL3 22 mm Green Push Button operator

22 mm Green Extended Push Button

The Schneider Electric ZB5AL3 is a 22 mm green extended push button designed for industrial control panels and machine interfaces. Its momentary action suits start, reset or jog functions where a tactile, projecting head is preferred. The plastic head, bezel and body resist corrosion and meet IP66 together with NEMA 1, 2, 3, 4 and 4X ratings. Compliance includes IEC 60947-1, IEC 60947-5-1, UL 508 and RoHS.

Panel cut-out and contact block

Verify that the mounting surface provides a standard 22 mm cut-out and sufficient depth behind the panel for the operator body and any contact blocks you intend to fit. The unit carries NEMA 13 and IP66 ratings, so confirm the enclosure sealing matches the environment. No legend plate is included; order one separately if identification is required. Wiring must follow the chosen contact block specifications.

Industrial panel builders and maintenance teams

This operator suits panel builders assembling new control stations and maintenance teams replacing worn buttons on existing machinery. Buyers who need an illuminated head, a mushroom-style operator or a maintained action should look at alternative models. Installations requiring a metal bezel or a different colour code will also need a different reference.
