Schneider Electric ZB4BA36 Push-button Switch 22mm Momentary

Product Description

The SCHNEIDER ELECTRIC ZB4BA36 is a 22 mm non-illuminated push-button switch operator designed for industrial control panel and machine tool applications. It features a recessed, round, green metal pushbutton with momentary (MO) operation, meaning the switch returns to its default state as soon as the operator releases pressure. The recessed design reduces the chance of accidental actuation in demanding environments. Rated to NEMA 4X and NEMA 13, this operator is built to handle wash-down, dust, and corrosive-atmosphere conditions. Licensed electricians and panel builders install this type of operator as part of a modular 22 mm push-button assembly.

This operator fits 22 mm mounting hole cutouts standard in industrial control enclosures, machine tool panels, and motor control centers. The green color convention signals a start or run function in most panel wiring practices. The ZB4BA36 is a metal-body operator intended for use in light industrial and heavy-duty commercial settings where panel vibration, contamination, or operator abuse is a factor. It is sold individually and is intended as a modular component that pairs with a compatible contact block and enclosure to form a complete switching assembly.

Compatibility

Designed as an OEM-style modular operator for 22 mm push-button assemblies in industrial control panels. Specific compatible contact blocks and mounting bases are not identified in the available product data and should be confirmed against the manufacturer documentation before ordering.

Installation Notes

Installation should be performed by a licensed electrician following applicable NEC and local electrical code requirements. De-energize and lock out the control panel before removing or installing any push-button operator. The operator threads into or clips onto a compatible 22 mm body and contact block assembly — confirm mechanical compatibility with the existing base before final assembly. Do not over-torque the mounting nut, as metal operators can crack panel substrates if forced.
