Schneider Electric ZB5AG3 3-position Key Selector Switch

Product Description

The SCHNEIDER ELECTRIC ZB5AG3 is a 3-position key-operated selector switch head designed for industrial control panel applications. It operates in a maintained (MA) mode, meaning the switch holds its selected position until physically moved. The black key can be removed only from the center position, adding a layer of access control to the operator interface. With a 22mm round head and plastic bezel, it installs into standard 22mm cutouts. This switch head is rated IP69K and NEMA 4X and 13, making it suitable for washdown, wet, and corrosive environments. Licensed electricians and control panel builders are the primary installers.

The ZB5AG3 is used in industrial and commercial control panel applications where key-controlled, multi-position selector functionality is required. Typical installations include machine control stations, process control enclosures, and operator interface panels exposed to moisture, dust, or high-pressure washdown conditions. Its 3-position maintained configuration is common in applications that require distinct operating modes such as manual, off, and automatic selections.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize the control panel and verify zero voltage before beginning installation or removal. Mount the switch head into a 22mm panel cutout and secure with the appropriate locking nut before attaching contact blocks. Do not overtighten the bezel assembly, as this may crack the plastic head.
