Schneider Electric ZB4BA48 Momentary Push-button Switch

Product Description

The SCHNEIDER ELECTRIC ZB4BA48 is a non-illuminated, momentary push-button switch operator designed for industrial control panel applications. It features a flush-profile, round red metal button and mounts through a 22 mm panel hole. The operator is constructed from metal for durability in demanding environments and carries a NEMA 4X and 13 rating, making it suitable for wet, dusty, and corrosive locations. Electricians and control panel builders install this switch as a discrete operator head in machine control, motor control centers, and industrial automation panels. The momentary action returns the button to its resting state immediately upon release.

This push-button operator is intended for use in industrial and commercial control panel assemblies where a 22 mm mounting footprint is required. Typical applications include machine start/stop stations, conveyor controls, pump panels, and process equipment enclosures. The red color convention is commonly associated with stop or emergency-function designations in control panel layouts. As a replacement or new-installation operator head, it fits into the Schneider Electric ZB4 modular push-button platform, which accepts separate contact block assemblies.

Key Features

• 22 mm mounting hole diameter fits standard industrial panel cutouts
• Flush round red metal button operator — non-illuminated
• Momentary action: returns to neutral position upon release
• NEMA 4X and 13 rated for wash-down, dust-tight, and corrosion-resistant enclosures
• Meets UL 508, CSA C22.2 No. 14, EN/IEC 60947-5-1, and multiple marine and international standards
• Metal construction for extended service life in industrial environments

Compatibility

Designed as an OEM-style operator head for the Schneider Electric ZB4 modular 22 mm push-button platform, requiring a separately ordered contact block for circuit completion.

Installation Notes

Installation is performed by a licensed electrician or qualified control panel technician. De-energize and lock out the control panel before removing any existing operator or installing this switch. The operator head mounts through a 22 mm panel cutout and typically secures with a threaded retaining ring; a contact block must be attached separately to complete the switching circuit. Follow NEC and applicable local codes for industrial control wiring and enclosure requirements.
