Schneider Electric ZB4BPA2 Push-button Switch 22mm Momentary

Product Description

The SCHNEIDER ELECTRIC ZB4BPA2 is a momentary, nonilluminated push-button switch designed for industrial control panel applications. It features a flush-style, round black actuator with a chromium-plated metal bezel and a 22 mm mounting hole diameter, making it a standard fit for 22 mm cutout enclosures. The momentary (MO) operation type means the switch activates only while pressed and returns to its off state on release. It carries ratings for NEMA 4X and NEMA 13 enclosures and meets multiple international standards including UL 508, CSA C22.2 No. 14, and EN/IEC 60947-5-1. Electricians and industrial control technicians are the primary installers of this device.

The ZB4BPA2 is suited for use in machine control panels, operator interface stations, and industrial automation equipment where a durable, corrosion-resistant momentary pushbutton is required. Its shock-resistant and vibration-resistant construction makes it appropriate for demanding environments such as manufacturing floors, pump stations, and process control enclosures. The NEMA 4X rating confirms suitability for washdown and corrosive-atmosphere installations. This switch is sold as a single unit and is a direct replacement or web-only SKU in the Schneider Electric ZB4 series product family.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the NEC and applicable local electrical codes. De-energize the control panel and verify absence of voltage before removing or installing any push-button operator. Use the appropriate panel punch or chassis knockout to maintain the 22 mm mounting hole tolerance. Ensure the bezel and mounting hardware are tightened to the enclosure to preserve the NEMA 4X and NEMA 13 ingress protection ratings.
