Schneider Electric ZB5AR2 Momentary Push-button 22 Mm

Product Description

The SCHNEIDER ELECTRIC ZB5AR2 is a momentary push-button operator designed for industrial and commercial control panel applications. This nonilluminated, extended mushroom-head operator features a round black plastic button and mounts through a 22 mm panel cutout. It is a discrete switching element intended for use with compatible contact blocks to complete a control circuit. Licensed electricians and panel builders install this component when assembling or servicing machine control stations, motor starters, and similar low-voltage operator interface assemblies. The part carries multiple certifications including UL Listed, CSA, and EN/IEC 60947-5-1, making it suitable for demanding industrial environments.

The ZB5AR2 is used in industrial control panels, machine tool stations, and process automation equipment across both light and heavy commercial applications. Its 22 mm mounting diameter is a standard size in modular operator systems, allowing it to fit into compatible legend plates, operator housings, and enclosures rated for NEMA 4X and NEMA 13 environments. Electricians and controls technicians select this operator when replacing worn or damaged push-button heads on existing control stations without replacing the entire assembly.

Key Features

• Momentary (MO) operation returns the button to its default position upon release
• Extended mushroom-head profile for high-visibility or emergency-stop style actuation
• Nonilluminated design eliminates the need for indicator lamp wiring
• Black round plastic button fits standard 22 mm panel cutouts
• NEMA 4X and NEMA 13 ratings support washdown and dust-tight enclosure applications
• Certified to UL 508, CSA C22.2 No. 14, EN/IEC 60947-5-1, and additional international standards

Compatibility

Designed as an OEM-style replacement operator head for 22 mm modular push-button control station systems. No specific compatible model numbers were provided in the product data.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the NEC and applicable local codes. De-energize and lock out the control panel before removing or installing any push-button operator or contact block. Verify that the mounting panel thickness and cutout diameter are compatible with the 22 mm mounting requirement before assembly. Do not overtighten the mounting nut, as the plastic operator body can crack under excessive torque.
