Schneider Electric ZB4BH02 Maintained Push-button Switch

Product Description

The SCHNEIDER ELECTRIC ZB4BH02 is a maintained-action push-button switch designed for industrial control panel applications. It features a flush-style, round black metal pushbutton head with a 22 mm mounting hole diameter, fitting standard 22 mm panel cutouts. The maintained (MA) operation type means the switch holds its actuated state until pressed again, making it suitable for on/off control functions where a latching output is required. Licensed electricians and control panel builders install this component during panel assembly or field service. It carries a NEMA 4X and NEMA 13 rating, confirming resistance to dust, oil, and water ingress in demanding environments.

The ZB4BH02 is used in industrial and commercial control panels where a reliable, panel-mount maintained pushbutton is needed. Typical applications include machine control stations, motor starter panels, and process control enclosures in manufacturing, utilities, and heavy industry. The 22 mm mounting format is a widely adopted standard in industrial controls, making this switch a common specification in new panel builds and retrofit service work. Its metal construction suits environments where plastic actuators would be vulnerable to mechanical damage or chemical exposure.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements and local codes. De-energize and lock out the control panel before removing or installing any push-button components. A standard panel punch or existing 22 mm cutout is required for mounting. Verify the switch operation type and circuit logic before restoring power to the panel.
