Schneider Electric ZB4BC24 Momentary Push-button Switch

Product Description

The SCHNEIDER ELECTRIC ZB4BC24 is a 22 mm momentary push-button switch designed for industrial control panel applications. It features a black, round, extended mushroom-head operator made from metal, providing a durable and tactile actuation point. The switch is non-illuminated and operates on a momentary (MO) contact principle, returning to its default state immediately upon release. Licensed electricians and panel builders install this component in motor control centers, machine control stations, and operator interface enclosures. It carries UL 508 listing and meets multiple international standards, making it suitable for both domestic and global equipment builds.

The ZB4BC24 is intended for use in industrial and commercial control panel assemblies where a 22 mm mounting hole is required. Its NEMA 4X and NEMA 13 ratings make it appropriate for wash-down environments, chemical-exposure areas, and outdoor enclosures where ingress protection is a priority. The extended mushroom-head profile is commonly specified in emergency-stop-adjacent layouts or anywhere a larger contact surface aids operator response. This switch fits within the Harmony XB4 series modular push-button platform.

Key Features

• 22 mm mounting hole diameter for standard industrial panel cutouts
• Momentary (MO) operation — returns to default state upon release
• Extended round mushroom-head operator in black metal construction
• Non-illuminated design simplifies wiring and reduces component count
• NEMA 4X and NEMA 13 ratings suit wet and corrosive environments
• UL 508 listed with Bureau Veritas, CSA, DNV, GL, and IEC certifications

Compatibility

Designed as an OEM-style replacement or new-installation push-button operator for 22 mm industrial control panel stations requiring a momentary, non-illuminated, extended mushroom-head actuator.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements and the panel manufacturer's documentation. De-energize and lock out the control panel before removing any existing operator or installing this switch. The 22 mm panel cutout must be clean and free of burrs to ensure proper seating and maintain the NEMA ingress protection rating. Do not exceed the contact ratings specified in the product datasheet.
