22 mm flush momentary push button with IP66 and NEMA 1, 2, 3, 4, 4X, 13 ratings for industrial control panels
This Schneider Electric ZB5APA2 operator is a 22 mm flush push button with momentary action. It suits industrial control panels that need a compact, panel-mounted actuator for start, stop or reset functions. The plastic head, bezel and booted button construction keeps weight low while meeting common enclosure requirements.
The operator carries NEMA 1, 2, 3, 4, 4X and 13 ratings plus IP66, so it resists dust, water jets and oil ingress in indoor or outdoor cabinets. Compliance with IEC 60947-1, IEC 60947-5-1, IEC 60947-5-4, UL 508, CSA C22.2 No. 14 and multiple marine and vibration standards means it fits regulated machinery builds without extra certification work.
The 22 mm mounting diameter matches standard industrial cut-outs, so the operator drops in and secures with a locking nut behind the panel. No separate contact blocks or legend plates are included, so installers must order matching ZB5 contact elements and any labelling separately. Verify panel thickness limits against the datasheet before cutting.

The head is moulded from a single piece of plastic rated to IP66 and NEMA 4X, so it resists dust, water jets and corrosion; no scheduled replacement interval is defined for the operator itself.
Mechanical endurance is governed by the internal spring and contact block (sold separately); the operator meets IEC 60947-5-1 durability tests, but the exact cycle count depends on the contact block chosen.
The operator is a passive plastic component with no electrical dissipation; it remains at ambient temperature regardless of duty cycle.
