Schneider Electric ZB4BPA4 Push-button Switch 22mm

Product Description

The SCHNEIDER ELECTRIC ZB4BPA4 is a momentary push-button switch designed for industrial control panel applications. It features a flush-mount, round, red metal operator with a 22 mm mounting hole diameter and non-illuminated construction. The momentary (MO) action means the switch activates only while depressed and returns to its default state upon release. Rated NEMA 4X and 13, this unit is built to resist dust, oil, and water ingress, making it suitable for demanding environments. Certified to UL 508, CSA C22.2 No. 14, and multiple IEC standards, it meets the requirements for industrial control equipment installations.

This push-button switch is used in industrial and commercial control panels, machinery, and automation systems where a momentary operator is required. The red flush-button format is commonly specified for stop, reset, or alarm-acknowledgment functions on operator interface panels. It is installed by licensed electricians and industrial controls technicians as part of a larger control station or enclosure assembly. Its compact form factor and broad certification list make it suitable for domestic and international installations.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC requirements and applicable local codes. De-energize the control panel and verify zero voltage before mounting or wiring the switch. The 22 mm panel cutout must be clean and free of burrs to ensure proper seating and NEMA-rated sealing. Follow the manufacturer contact block wiring documentation when connecting downstream control circuit wiring.
