ZB4BZ101 is a Harmony XB4 22 mm contact block (body with fixing collar) designed to mate with Harmony XB4 metal push-button heads and the XB5 plastic ranges, and it ships with a mounting collar. It provides one normally open (1 NO) contact and uses screw-clamp terminals for secure, permanent wiring, making it suitable for general-purpose, low-current control circuits within 22 mm push-button assemblies. This compact, stackable block leverages Schneider Electric’s push-in technology to streamline wiring in panel-mounted applications and to extend the functionality of Harmony XB4/ XB5 operator sets.
