A green 22 mm flush momentary push button operator rated IP66 and NEMA 13, 4X for industrial control panels
This Schneider Electric ZB5AW533 is a 22 mm flush momentary push button operator designed for industrial control panels and automation systems. The green plastic head and bezel provide clear visual identification in machinery interfaces. It suits panel builders and maintenance engineers who need a reliable momentary actuation device for start, reset or signal functions.
The operator meets IP66 ingress protection and NEMA Type 13 and 4X ratings, resisting dust, water jets and oil exposure in harsh environments. Plastic construction across the head, bezel and boot eliminates corrosion risk. Compliance with IEC 60529, IEC 60068-2-6 and IEC 60068-2-27 confirms durability under vibration and shock conditions.
Certified to EN/IEC 60947-1, EN/IEC 60947-5-1, EN/IEC 60947-5-4, UL 508, CSA C22.2 No. 14, GB 14048.5 and marine approvals including DNV, GL and LROS, the button maintains performance during prolonged duty cycles. RoHS compliance and REACH freedom from SVHC substances support regulated installations. It is not suited for applications requiring maintained latching action or illuminated indication.

Mount the operator in a 22 mm panel cut-out, secure the locking nut to the rated torque, then clip the contact block onto the back — skipping the contact-block clip leaves the circuit open.
The plastic head and bezel resist IP66 ingress; inspect the boot seal periodically and replace the operator if the green colour fades or the momentary action feels soft.
The mechanical endurance of the momentary mechanism is the first limit; the IP66 seal and NEMA 13/4X rating remain effective as long as the boot is intact.
