Schneider Electric ZB4BPA5 Push-button Switch 22mm Momentary

Product Description

The SCHNEIDER ELECTRIC ZB4BPA5 is a momentary (MO) push-button switch designed for industrial control panel applications. It features a flush-style, round yellow actuator with a chromium-plated metal bezel and mounts through a 22 mm panel hole. The switch is non-illuminated and rated for NEMA 4X and NEMA 13 enclosures, making it suitable for wet, dusty, and corrosive environments. Built to withstand shock and vibration, the ZB4BPA5 meets multiple international standards including UL 508, CSA C22.2 No. 14, and EN/IEC 60947-5-1. Licensed electricians and control panel builders are the primary installers of this component.

The ZB4BPA5 is used in industrial and commercial control panel assemblies where a momentary switching action is required. Typical applications include machine control stations, operator interface panels, and process equipment. The yellow color designation commonly signals a caution or specific functional assignment in panel layouts. Its NEMA 4X rating makes it appropriate for washdown environments and outdoor enclosures where moisture and contamination resistance are required.

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 switching component. The 22 mm mounting hole should be deburred and clean before seating the bezel to maintain the NEMA 4X enclosure rating. Do not overtighten the mounting hardware, as this can deform the bezel seal and compromise ingress protection.
