Schneider Electric ZB4BW153 Momentary Push-button Switch

Product Description

The SCHNEIDER ELECTRIC ZB4BW153 is a non-illuminated, momentary push-button switch operator designed for industrial control panel applications. It features a round, orange, extended straight metal button that fits a 22 mm mounting hole. The momentary contact action returns to its normal position as soon as pressure is released, making it suitable for start, stop, and jog functions. Rated NEMA 4X and 13, this operator is built to resist dust, oil, and corrosive environments. It meets a broad range of international standards including UL 508, CSA C22.2 No. 14, and EN/IEC 60947-5-1, confirming suitability for demanding service environments.

The ZB4BW153 is used in residential, commercial, and industrial control panel builds and retrofits. It is a standard 22 mm format operator, compatible with the Harmony XB4 panel-mount push-button body platform. Electricians and panel builders install this operator when a clearly visible orange momentary actuator is required, such as for warning functions, emergency jog controls, or operator-interface stations. The orange color provides quick visual identification at a panel face. It is sold as a single unit per package.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements and local codes. De-energize the control panel and verify zero voltage before removing or installing any operator or contact block. The operator threads or snaps into a 22 mm panel cutout — confirm panel thickness is within the accepted range for the mounting hardware before assembly. Do not overtighten the locking nut, as metal operators can crack the panel face material if excessive force is applied.
