Schneider Electric ZB4BA46 Momentary Push-button Switch

Product Description

The SCHNEIDER ELECTRIC ZB4BA46 is a non-illuminated, momentary push-button switch operator designed for industrial control panel applications. It features a recessed, round, red metal pushbutton mounted through a 22 mm diameter panel hole. The recessed profile reduces the risk of accidental actuation, making it well suited for emergency-stop or process-control circuits where inadvertent contact must be minimized. At 0.07 pounds, the unit is compact and lightweight. It carries a NEMA 4X and NEMA 13 rating, confirming suitability for wash-down and corrosive-environment enclosures. Licensed electricians and panel builders are the primary installers of this device.

This push-button operator is used in industrial and commercial control panels, machine tool enclosures, and process-automation equipment. The 22 mm mounting standard is widely adopted across industrial controls, making this operator a common fit for new panel builds and field replacements. It is applicable in environments requiring resistance to water, oil, and dust ingress, consistent with its NEMA 4X and NEMA 13 ratings. The momentary action returns the contacts to their normal state immediately upon release, which is the correct behavior for start, jog, and momentary-command functions.

• Meets UL 508, CSA C22.2 No. 14, EN/IEC 60947-5-1, and multiple additional international standards

Compatibility

Designed as an OEM-style replacement or new-installation operator for 22 mm industrial push-button stations and control panel cutouts conforming to the 22 mm mounting standard.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC Article 430 and applicable local codes. De-energize and lock out the control panel before installing or replacing the operator. Verify the panel cutout is 22 mm and that the enclosure rating matches or exceeds the environmental requirements of the installation. Do not over-torque the mounting nut, as this can crack the operator body or distort the panel material.
