Industrial 22 mm potentiometer
The Schneider Electric ZB4BD922 is a non-illuminated selector switch with an integrated potentiometer. It mounts in a standard 22 mm panel cut-out and carries NEMA ratings 1, 2, 3, 4, 4X, 12 and 13. The unit suits industrial control panels that require manual analogue adjustment in protected environments.
Replacing worn selector pots
This component replaces a failed or ageing potentiometer in an existing 22 mm operator station. The upgrade is justified when the original device no longer holds calibration or its sealing has degraded. It is not suited for applications that demand digital encoding, illuminated feedback or a different mounting diameter.
NEMA-rated sealing limits
The listed NEMA ratings cover indoor and outdoor protection against dust, water ingress and corrosion. The device does not carry hazardous-location certifications such as NEMA 7 or 9, so it cannot be installed in classified explosive atmospheres. Users must verify that the panel enclosure maintains the same rating after installation.

Questions about this item
What panel cut-out diameter does the 22 mm Schneider Electric ZB4BD922 potentiometer require?
The operator fits a standard 22 mm panel cut-out, matching the 22 mm size stated for the ZB4BD922.
How is the ZB4BD922 potentiometer mounted, and which step is often missed?
Insert the operator through the 22 mm hole, secure the anti-rotation collar, then tighten the locking nut — skipping the collar lets the body rotate under torque.
Which NEMA-rated seal on the ZB4BD922 potentiometer may need replacement after extended use?
The front-panel gasket that provides NEMA 1, 2, 3, 4, 4X, 12 and 13 sealing can degrade and should be inspected periodically.
