22 mm momentary mushroom push button with metal head and bezel, rated IP66 and NEMA 1, 2, 3, 4, 4X, 13 for industrial panels
The Schneider Electric ZB4BC24 is a 22 mm mushroom-head push button designed for industrial control panels and automation equipment. Its momentary action suits start, stop or emergency functions where a distinct, tactile operator is required. The metal head, bezel and base construction withstand harsh environments in manufacturing, process and marine applications.
Rated IP66 and NEMA 1, 2, 3, 4 and 4X, the operator resists dust ingress and powerful water jets during continuous operation. Compliance with IEC 60068-2-6 and IEC 60068-2-27 confirms vibration and shock endurance, while IEC 60529 and Bureau Veritas certification validate long-term sealing integrity. The RoHS and REACH declarations confirm restricted-substance compliance for regulated markets.
Verify that the mounting cut-out matches the 22 mm size and that the panel thickness suits the operator's clamping range. Confirm the control circuit voltage and current align with the contact blocks you will pair with this head, as the head itself carries no electrical rating. Ensure the enclosure rating meets the required NEMA or IP class for the installation zone.

The push button is a passive mechanical operator with no internal power draw, so it generates no heat and produces no audible noise during momentary actuation.
It fits a standard 22 mm panel cut-out and requires a compatible Schneider Electric contact block or LED block that snaps onto the back of the operator.
Yes, the operator is certified to EN/IEC 60947-5-1 and carries the same NEMA 1, 2, 3, 4, 4X, 13 ratings as legacy industrial panels.
