Schneider Electric ZB4BW13 Push-button Switch 22mm Momentary

Product Description

The SCHNEIDER ELECTRIC ZB4BW13 is a 22 mm momentary push-button switch designed for industrial control panel applications. It features a round, extended (straight) green metal pushbutton with a non-illuminated operator. The momentary (MO) action means the switch activates only while depressed and returns to its default state upon release. Rated for NEMA 4X and 13 enclosures, the ZB4BW13 meets a broad range of international standards including UL 508 and EN/IEC 60947-5-1, making it suitable for demanding indoor and wash-down environments. Electricians and panel builders typically specify this switch for machine control, process equipment, and operator interface stations.

The ZB4BW13 is used in residential, commercial, and industrial control panels where a compact, corrosion-resistant momentary operator is required. Its 22 mm mounting hole diameter fits standard 22 mm cutout panel openings common across control enclosures and operator consoles. The green color convention typically signals start, run, or go functions in machine and process control wiring. The extended button profile provides positive tactile feedback, which is useful in high-glove-use environments such as manufacturing floors, pump stations, and mechanical rooms.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements and applicable local codes. De-energize and lock out the control panel before removing any existing operator or making wiring connections. Use a 22 mm punch or step drill to prepare the panel cutout if installing in a new location. Verify enclosure NEMA rating compatibility before mounting to ensure the assembly maintains its environmental sealing.
