22 mm Mushroom Head Push Button for Industrial
The Schneider Electric ZB4BC3 is a 22 mm mushroom head push button designed for industrial control panels. Its momentary action suits machine start, stop or emergency functions where a large, tactile operator is required. The green colour provides clear visual identification on crowded panels. Metal construction throughout ensures durability in demanding environments.
NEMA 1 2 3 4 4X 13 and IP66 IP67 IP69 IP69K
The operator carries NEMA ratings 1, 2, 3, 4, 4X and 13 alongside IP66, IP67, IP69 and IP69K. These ratings confirm protection against dust ingress, high-pressure water jets and temporary immersion. The metal bezel and head maintain sealing integrity under mechanical stress. No legend plate is included, so marking must be sourced separately.
Verify 22 mm Cutout and Momentary Logic Before
Confirm the panel cutout matches the 22 mm mounting standard used by this operator. The 40 mm mushroom head diameter requires adequate spacing from adjacent devices. Ensure the control circuit expects a momentary contact rather than a maintained or latching function. Metal panel thickness and grounding provisions should also be reviewed.
