Schneider Electric ZB5AG0 3-position Key Selector Switch

Product Description

The SCHNEIDER ELECTRIC ZB5AG0 is a 3-position key-operated selector switch head designed for industrial and commercial control panel applications. It uses a maintained (MA) operation type, meaning the switch holds its selected position until manually moved. The black key can be removed at any position, which adds a layer of access control in environments where operator lockout is required. Rated IP69K, this selector switch head resists high-pressure washdowns, making it suitable for demanding environments. The round head fits a standard 22 mm panel cutout and features a plastic bezel construction. Licensed electricians and controls technicians are the primary installers.

The ZB5AG0 is suited for use in light industrial, food processing, marine, and commercial facilities where moisture, vibration, or shock exposure is a concern. Its IP69K and NEMA 4X ratings make it appropriate for wet or wash-down locations. The NEMA 13 rating covers oil-tight indoor applications as well. This switch operator head is typically wired into machine control circuits, motor starters, or automation panels requiring a key-controlled multi-position selector input. It is sold as the operator head only and requires a separate contact block assembly to complete the switching function.

Installation Notes

Installation should be performed by a qualified electrician or controls technician in accordance with NEC requirements and local codes. De-energize the control panel and lock out all power sources before beginning installation or removal. The operator head mounts through a 22 mm panel cutout and secures with the appropriate mounting collar or nut. This part is the operator head only — do not attempt to use it as a complete switching device without attaching a rated contact block.
