Schneider Electric ZB5AG7 3-position Key Selector Switch 22mm

Product Description

The SCHNEIDER ELECTRIC ZB5AG7 is a 3-position momentary key selector switch operator designed for industrial control panel applications. It uses a black key for actuation and returns to center when released, following the momentary (MO) operation type. The operator fits a standard 22mm round mounting hole and carries an IP69K ingress protection rating, making it suitable for wet, washdown, and high-pressure cleaning environments. The round head is constructed with a plastic bezel and is rated NEMA 4X and NEMA 13 for corrosion and moisture resistance. Licensed electricians and control panel builders install this component as part of larger switch assemblies.

This selector switch operator is used in industrial and commercial control panel builds where a spring-return, 3-position key switch is required. Typical applications include machine control stations, motor starters, and equipment requiring key-controlled momentary actuation. The shock-resistant and vibration-resistant construction suits demanding production floor environments. The key removal position is at center, which is standard practice for access control and tamper-resistance in industrial automation circuits.

Key Features

• 3-position momentary (MO) operation with spring return to center
• 22mm round mounting hole for standard panel cutout compatibility
• IP69K rating — withstands high-pressure, high-temperature washdown
• NEMA 4X and NEMA 13 rated for corrosion and moisture resistance
• Black key operator with key removal at center position
• Shock-resistant and vibration-resistant plastic bezel construction

Compatibility

Designed as an OEM-style operator head for 22mm modular selector switch assemblies requiring a 3-position momentary key configuration. Specific contact block and base compatibility should be verified against the manufacturer's 22mm Harmony XB5 series documentation provided in the input data.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC and applicable local codes. De-energize the control panel and lock out the power source before mounting or replacing the operator. The 22mm hole diameter requires a standard punch or existing panel cutout of the correct size — do not force-fit into an undersized opening. Verify that any mating contact blocks are rated and assembled to the operator before returning the panel to service.
