Schneider Electric ZB5AD28 2-position Selector Switch

Product Description

The SCHNEIDER ELECTRIC ZB5AD28 is a 2-position maintained selector switch operator designed for industrial and commercial control panel applications. It features a black toggle operator with a round head and non-illuminated bezel, housed in a plastic head rated for IP66 ingress protection and NEMA 4X and 13 environments. This operator is shock-resistant, vibration-resistant, and water-resistant, making it suitable for demanding installation conditions. It is installed by licensed electricians and control panel builders working on machine control, process equipment, and automation systems. The ZB5AD28 is a switch operator only and requires a compatible contact block to complete the assembly.

This operator suits industrial control stations, enclosures, and machine panels requiring a maintained 2-position switching function. It fits a 22 mm round mounting hole, a standard diameter across industrial control devices. Typical applications include motor start-stop controls, selector functions for multi-speed or directional motor circuits, and mode selection on automated process equipment. The maintained operation type means the toggle holds its selected position until manually moved, making it appropriate for persistent on-off or dual-mode circuit control.

Key Features

• 2-position maintained operation holds selected state without spring return
• Black toggle operator with round head for standard control panel aesthetics
• 22 mm round mounting hole diameter for compatibility with standard industrial cutouts
• IP66 and NEMA 4X and 13 ratings provide resistance to dust, water jets, and oil splashing
• Shock-resistant and vibration-resistant construction for industrial environments
• Non-illuminated operator keeps installation wiring simple with no pilot light circuit required
• Certified to UL 508, CSA C22.2 No. 14, EN/IEC 60947-5-1, and multiple international standards

Compatibility

Designed as an OEM-style selector switch operator for use in 22 mm industrial control station assemblies. Requires a separately sourced compatible contact block to form a complete switching assembly.

Installation Notes

Installation should be performed by a qualified electrician following applicable NEC requirements and panel builder standards. Disconnect and lock out all power to the control enclosure before removing or installing switch operators or contact blocks. The 22 mm mounting hole should be deburred and verified to dimension before insertion. Do not over-torque the mounting nut, as the bezel material is plastic and may crack under excessive force.
