Schneider Electric ZB5AH04 Push-button Switch 22mm

Product Description

The SCHNEIDER ELECTRIC ZB5AH04 is a maintained-action push-button switch designed for industrial control panel applications. It features a flush, round, red plastic operator in a nonilluminated configuration and mounts through a 22 mm panel hole. The maintained (MA) operation type means the switch holds its actuated position until deliberately reset, making it suitable for on/off control functions that require a stable switching state. Weighing 0.03 pounds, the ZB5AH04 carries a NEMA 4X and NEMA 13 rating, indicating resistance to dust, oil, and washdown conditions. Licensed electricians and panel builders are the typical installers.

The ZB5AH04 is used in industrial and commercial control panels where a reliable maintained push-button operator is required. Its NEMA 4X rating makes it appropriate for environments exposed to moisture, non-corrosive liquids, and dust ingress. The flush button profile reduces the risk of accidental actuation in close-quarters panel layouts. Applications include machine control stations, process equipment panels, and operator interface assemblies where a clearly identified red stop or hold function is needed.

Key Features

• Maintained (MA) operation holds switch position after actuation without continuous operator pressure
• 22 mm mounting hole diameter fits standard 22 mm panel cutouts
• Flush, round red operator provides clear visual identification for stop or hold functions
• Nonilluminated design simplifies wiring and eliminates pilot light circuit requirements
• NEMA 4X and NEMA 13 ratings suit washdown, dust, and oil-splash environments
• Plastic operator construction with broad multi-standard certification coverage

Compatibility

Designed as an OEM-style replacement or new-installation push-button operator for industrial control panels using standard 22 mm mounting hole cutouts.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements and applicable local codes. De-energize and lockout/tagout the control panel before installing or replacing any push-button operator. Ensure the panel cutout diameter matches the 22 mm mounting hole requirement before mounting. Verify that the maintained-action switching logic is compatible with the control circuit before restoring power.
