- Description
The Schneider Electric ZB4BA333 is a Harmony XB4 flush push-button head with a green chromium-plated metal bezel marked START in white, for a 22 mm panel cutout. It operates on a spring return action and snaps onto a Harmony XB4/ZB4 contact block, giving the operator a labelled start/run function without a separate legend plate.

Selection Notes
IEC 60947-5-1 reserves green for start/run actuators, so the ZB4BA333's green bezel and START legend let an operator identify the function at a glance without reading a separate plate. Pair it with a Harmony contact block carrying the NO contacts the start circuit needs; use the unmarked ZB4BA3 green head instead where a custom legend plate will be fitted on site.
