Schneider Electric ZB4BR4 Push-button Switch 22mm Red

Product Description

The SCHNEIDER ELECTRIC ZB4BR4 is a heavy-duty push-button switch designed for industrial control panel applications. It features a 22 mm mounting hole diameter, a red extended mushroom-head operator, and momentary (MO) operation, meaning the contact state returns to normal the instant the button is released. The operator body is constructed from metal for durability in demanding environments. This switch carries a NEMA 4X and 13 rating, making it suitable for washdown and corrosive-environment installations. It is non-illuminated. Licensed electricians and industrial control panel builders are the primary installers of this component.

The ZB4BR4 is used in industrial and commercial control panel applications where a clearly visible, tactile momentary actuation point is needed. The red mushroom-head profile is commonly applied to emergency-stop adjacent functions, machine jog controls, or process reset circuits. The 22 mm format fits standard metric control panel cutouts found across a wide range of machine tool, process automation, and conveyor control enclosures. Its NEMA 4X rating supports use in food processing, marine, and outdoor environments where moisture and contaminant ingress is a concern.

Compatibility

Designed as an OEM-style replacement or new-installation push-button operator for 22 mm metric control panel assemblies in industrial and commercial applications.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC Article 430 or applicable local codes. De-energize and lock out the control panel before installing or replacing the operator. The 22 mm panel cutout should be clean and free of burrs before mounting to ensure proper sealing and NEMA rating integrity. Do not overtighten the mounting nut, as this may crack the panel material or distort the seal.
