Schneider Electric ZB4BW37 Momentary Push-button Switch

Product Description

The SCHNEIDER ELECTRIC ZB4BW37 is a momentary push-button switch designed for industrial control panel applications. It features a flush-mount, round, clear nonilluminated operator and mounts through a 22 mm panel hole. The operator body is metal construction, rated NEMA 4X and 13, making it suitable for wet, dusty, and corrosive environments. Weighing 0.05 pounds and measuring approximately 1.3 x 1.2 x 1.3 inches, it is a compact, single-unit replacement part installed by licensed electricians and control panel builders. It carries UL 508 listing and meets multiple international standards including EN/IEC 60947-5-1.

The ZB4BW37 is used in industrial and commercial control panel assemblies where a momentary, nonilluminated operator is required. Typical applications include machine tool controls, motor starter stations, and process control panels. The clear flush-button design suits installations where operator contact verification is needed without illumination. Its NEMA 4X rating qualifies it for indoor and outdoor enclosures exposed to washdowns, rain, or corrosive atmospheres. This switch is sold as a single-unit replacement component.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize and lock out the control panel before removing or installing any push-button operator. Verify the panel cutout diameter matches the 22 mm mounting requirement before installation. Do not overtighten the mounting nut, as this may crack the operator body or distort the panel surface.
