Schneider Electric ZB4BPA3 Push-button Switch 22mm Momentary

Product Description

The SCHNEIDER ELECTRIC ZB4BPA3 is a non-illuminated, momentary push-button switch designed for industrial and commercial control panel applications. It features a flush-mounted, round green metal operator with a 22 mm mounting hole diameter. The momentary (MO) action returns to its default state immediately upon release, making it suitable for start, stop, or signal functions. Rated NEMA 4X and 13, this switch meets demanding environmental standards including resistance to washdown and corrosion. It carries multiple international certifications, including UL 508, CSA C22.2 No. 14, and EN/IEC 60947-5-1, confirming its suitability for control circuit applications.

The ZB4BPA3 is used in industrial control panels, machine tool enclosures, and process control stations where a robust, corrosion-resistant momentary actuator is required. The green color convention typically indicates a start or run function in standard control circuit wiring practice. Its 22 mm mounting hole diameter is a widely adopted format across industrial panel components, making it compatible with standard 22 mm cutout enclosures and panel layouts found in both light and heavy industrial installations. Licensed electricians and control panel builders are the primary installers of this component.
