Schneider Electric ZB5APA4 Momentary Push-button Switch

Product Description

The SCHNEIDER ELECTRIC ZB5APA4 is a momentary push-button switch designed for industrial control panel applications. It features a flush-mount, round, red plastic actuator with a 22 mm mounting hole diameter and non-illuminated operation. The switch is shock-resistant and vibration-resistant, making it suitable for demanding environments. Licensed electricians and control panel technicians typically install this type of operator as part of motor control, signaling, or machine-stop circuits. It carries multiple international certifications and meets NEMA 4X and 13 enclosure ratings for use in wet or contaminated locations.

This push-button operator fits 22 mm standard control station cutouts common in industrial and commercial electrical panels. It is suited for momentary contact applications such as start, stop, or jog commands on motor control centers, machine tool panels, and process control enclosures. The NEMA 4X rating makes it appropriate for washdown or outdoor installations where moisture and dust resistance are required. Installations in the United States are governed by NEC Article 430 for motor control and Article 409 for industrial control panels.

Key Features

• 22 mm mounting hole diameter fits standard industrial control cutouts
• Momentary operation returns to neutral when released
• Flush-mount, round, red plastic actuator for quick operator identification
• Non-illuminated design simplifies wiring and reduces panel complexity
• Shock-resistant and vibration-resistant construction for industrial environments
• NEMA 13 and NEMA 4X ratings suitable for wet and contaminated locations

Compatibility

Designed as an OEM-style replacement operator for 22 mm push-button control station assemblies requiring a flush, round, momentary actuator.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC and local electrical code requirements. De-energize and lock out the control panel before removing or installing any push-button operator. Ensure the mounting hole diameter matches the 22 mm cutout requirement before installation. Do not overtighten the mounting hardware, as plastic actuator bodies can crack under excessive force.
