Schneider Electric ZB4BG08 3-position Key Selector Switch

Product Description

The SCHNEIDER ELECTRIC ZB4BG08 is a 3-position momentary key selector switch designed for industrial control panel applications. The operator uses a black key that can be removed in the left position, and returns to center on release due to its momentary (MO) action. The round metal bezel fits a standard 22mm panel cutout. Built to withstand harsh environments, it carries an IP69K ingress protection rating and is rated for NEMA 13 and 4X enclosures, making it suitable for washdown and high-pressure spray conditions. Shock-resistant and vibration-resistant construction supports reliable performance in demanding industrial settings. Licensed electricians and control panel technicians are the typical installers.

The ZB4BG08 is used in industrial and commercial control systems where key-operated, 3-position momentary switching is required. Typical applications include machine control panels, process automation equipment, and enclosures subject to moisture, dust, or washdown cycles. The non-illuminated metal head is well suited for environments where NEMA 4X or NEMA 13 protection is specified. Its IP69K rating makes it a strong fit for food processing, chemical, and heavy manufacturing installations where high-pressure cleaning is routine.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NFPA 70 (NEC) and applicable local codes. De-energize the control panel and verify zero voltage before beginning any wiring work. The switch mounts through a 22mm panel cutout; secure the bezel hardware to the panel before making contact block connections. Do not exceed the electrical ratings of any attached contact block assemblies.
