Schneider Electric ZB4BL2 Push-button Switch 22mm

Product Description

The SCHNEIDER ELECTRIC ZB4BL2 is a 22 mm push-button switch operator designed for industrial and commercial control panel applications. It features a black, round, extended straight push button made of metal and operates on a momentary (MO) action, meaning it returns to its resting state when released. The operator is non-illuminated and mounts through a standard 22 mm panel cutout. It carries a NEMA 4X and NEMA 13 rating, making it suitable for use in wet, dusty, or corrosive environments. Licensed electricians and panel builders install this type of component as part of machine control stations, operator interface assemblies, and industrial control enclosures.

This operator is suited for use in industrial control panels, machine tool stations, and process control enclosures in both light commercial and heavy industrial settings. The 22 mm mounting format is a widely used standard in industrial controls, making this operator compatible with a broad range of panel cutouts and control station bodies that accept 22 mm components. Applications include motor control, emergency stop circuits, signaling, and other momentary-contact switching tasks where a non-illuminated actuator is appropriate.

Installation Notes

Installation is typically performed by a licensed electrician in accordance with NEC requirements and the equipment manufacturer's documentation. De-energize and lock out the control panel before installing or replacing any push-button operator. Verify that the mounting hole diameter and panel material are appropriate for the NEMA rating required by the application. Do not exceed the electrical ratings of the contact block assembly used with this operator.
