22 mm Flush Momentary Push Button
The Schneider Electric ZB4BW34 is a 22 mm flush push button with momentary action, built for industrial control panels and automation equipment. Its all-metal construction and red colour make it suited for operators who need a durable, clearly identified actuator in harsh environments.
NEMA 13, 4X and IP66 Sealing
The button carries NEMA 13 and 4X ratings together with IP66 protection, resisting dust, water jets and oil ingress without a separate gasket. Metal bezel and head materials withstand mechanical shock and vibration covered by IEC 60068-2-27 and IEC 60068-2-6, so the switch stays reliable in wet or dirty installations.
Direct Panel-Mount Replacement
This operator replaces worn or damaged 22 mm flush buttons on existing Schneider Electric ZB4 stations or compatible cut-outs, avoiding a full panel redesign. The jump is worth it when the original actuator has lost its seal or the legend has faded, and the application demands the same NEMA and IP ratings plus Bureau Veritas, CSA, DNV, GL, LROS, UL 508 and IEC 60947 compliance.

Questions about this item
How do I install the 22 mm flush push button and what is the common mistake?
Insert the operator through a 22 mm panel cut-out and secure with the locking nut; the step often missed is tightening to the specified torque so the IP66 seal seats evenly.
What maintenance or replacement will the ZB4BW34 need over time?
The momentary mechanism is rated for millions of cycles; only the red metal head or legend plate would need swapping if damaged, as the contact block is a separate module.
Which limit appears first during sustained operation?
Continuous duty is bounded by the IEC 60947-5-1 thermal current rating of the chosen contact block, not by the operator itself.
