Schneider Electric ZB5AZ009 22 mm plastic mounting base

22 mm plastic mounting base

The Schneider Electric ZB5AZ009 is a 22 mm plastic mounting base for Harmony XB5 and ZB5 modular push buttons, selector switches and pilot lights. It provides the foundation for round or square plastic bezel operators in industrial control panels. The snap-fit head and body lock together and are secured with a single screw for quick, reliable assembly. Shake-proof connection screws eliminate the need for periodic retightening in vibration-prone environments.

Suits panels built around 22 mm Harmony plastic

This base is intended for machine manufacturers and control-system integrators who use 22 mm plastic modular operators in automotive, textile, timber or similar production equipment. It supports both low-load electrical contacts and high-power applications with the same mounting footprint. Installers who require metal mounting collars or chromium-plated metal bezels should select the XB4 or ZB4 series instead, as this base is designed exclusively for the plastic Harmony range.

22 mm mounting diameter decides fit

The 22 mm diameter is the critical dimension that determines whether this base matches the panel cut-out and the operator head you are installing. Only Harmony XB5 and ZB5 plastic operators with a 22 mm mounting requirement are compatible with this base. Verify the panel cut-out and operator series before ordering to ensure correct mechanical and electrical integration.
