Schneider Electric ZB4BW313 Push-button Switch 22mm

Product Description

The SCHNEIDER ELECTRIC ZB4BW313 is a momentary push-button switch designed for industrial control panel applications. It features a flush-style, round white operator with a 22 mm mounting hole diameter and a non-illuminated metal pushbutton body. This switch is built to withstand demanding environments, carrying NEMA 4X and 13 ratings for protection against dust, oil, and corrosive agents. Licensed electricians and panel builders install this type of switch in control enclosures, machine panels, and automation systems where a momentary contact signal is required to initiate or stop a process.

The ZB4BW313 suits residential and commercial industrial control applications, including motor control centers, operator interface panels, and automated machinery. Its 22 mm mounting hole diameter is a widely adopted standard in control panel construction, making it a straightforward fit in new builds and retrofit projects. The white operator color is commonly used for neutral or start functions in panel color-coding conventions. This switch is appropriate for low-voltage control circuits handled by licensed electricians or qualified control panel technicians.

Key Features

• Momentary (MO) operation — contact closes only while the button is depressed
• 22 mm standard mounting hole diameter for broad panel compatibility
• Flush-style round white metal pushbutton operator
• Non-illuminated design simplifies wiring and reduces component count
• NEMA 4X and 13 rated for protection against dust, oil, and corrosion
• Meets UL 508, CSA C22.2 No. 14, and EN/IEC 60947-5-1 among other international standards

Compatibility

Designed as an OEM-style replacement or new-installation momentary push-button switch for 22 mm industrial control panel cutouts conforming to IEC and NEMA mounting standards.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC Article 430 or applicable local electrical codes. De-energize and lock out the control panel before mounting or wiring this switch. A standard 22 mm chassis punch or pre-drilled panel cutout is required for mounting. Verify contact block compatibility and circuit voltage rating before completing the wiring termination.
