Schneider Electric ZB5AH03 22 mm Green Push Button Operator

22 mm Green Push Button Operator

The Schneider Electric ZB5AH03 is a 22 mm flush push button designed for industrial control panels. It uses a maintained action so the contacts stay in the selected position until pressed again. The green colour provides clear visual identification on machinery and process equipment. Panel builders and maintenance engineers specify it for standard operator stations.

Replaces worn or missing 22 mm operators

This unit fits the industry-standard 22 mm mounting cut-out, allowing direct replacement of damaged buttons without re-drilling the enclosure. The jump is worth it when the existing head is cracked, the legend is illegible or the sealing has degraded. It is not for applications requiring momentary action, illuminated heads or a different colour code.

IP66 and NEMA 4X sealing for harsh environments

The plastic bezel and head meet IP66 and NEMA 1, 2, 3, 4, 4X, 13 ratings, resisting high-pressure wash-down and corrosive atmospheres. It comfortably handles food-processing splash zones, outdoor panels and chemical plant areas. It runs out where metal bezels are mandated by specification or where a keyed or mushroom-head operator is required for safety functions.
