Product Description

The SCHNEIDER ELECTRIC ZB4BZ079 is a fixing collar designed for use with Harmony XB4 series pushbutton control stations. This accessory secures the control station body during panel installation, maintaining proper alignment and mechanical retention of the operator interface. Measuring 1.2 inches in length, 1.1 inches in width, and 0.9 inches in height, it is a compact hardware component weighing 0.01 pounds.
