Features

The Schneider Electric ZB4BG2 is a 22mm key-operated selector switch head from the Harmony XB4 metal range. It provides a maintained, 2-position ($90 $) operation. In Canadian industrial facilities, this is the go-to component for "Auto/Manual" or "On/Off" selections where you want to prevent unauthorized personnel from changing the machine's operating state.
This unit uses the standard Ronis 455 key. While not a high-security "bank vault" lock, it provides a vital layer of operational safety. It ensures that only a supervisor or a qualified maintenance technician with the key can switch a machine from its programmed "Auto" mode into a "Manual" maintenance mode.
The "G2" designation indicates that the key can be removed in any position (left or right). This is a critical feature for Canadian plant managers; you can set the machine to "Auto" and remove the key to lock in that setting, or set it to "Manual" for a weekend shutdown and take the key with you to ensure no one re-starts the system prematurely.
As part of the XB4 series, the ZB4BG2 features a rugged metal bezel. It is designed to handle the grease, oil, and physical impacts common in Canadian workshops, sawmills, and manufacturing plants. It is much more durable than plastic versions, especially in extreme temperature fluctuations common in unheated Canadian industrial spaces.
Despite being a key switch, the ZB4BG2 maintains incredible sealing ratings. It is NEMA 4X and IP69K rated, making it suitable for high-pressure washdown environments like food processing or pharmaceutical plants. A small internal seal ensures that dust and water do not penetrate the lock cylinder.
