22 mm Flush Push Button Red

The Schneider Electric ZB4BA4 is a 22 mm flush push button in red designed for industrial control panels and automation systems. It provides momentary actuation for operators who need a reliable manual input device in demanding environments.

IP66 and IP69K sealed construction

The metal head bezel and base meet NEMA 1 2 3 4 4X 13 ratings and IP66 IP69K ingress protection so dust and high pressure washdown do not affect operation. Compliance with IEC 60529 IEC 60068 2 6 2 27 and UL 508 confirms durability under vibration shock and temperature cycling.

Metal build with 22 mm panel cutout

The all metal operator head bezel and mounting nut install in a standard 22 mm cutout and satisfy CSA C 22 2 No 14 EN IEC 60947 1 5 1 5 4 5 5 DNV GL LROS Bureau Veritas and IEC 60536 Class I. RoHS and REACH SVHC free materials suit regulated installations.

Questions about this item

How do I mount this 22 mm flush push button in a panel, and which step is often missed?

Drill a 22 mm hole, insert the operator, and secure the metal bezel with the locking nut; the step often missed is tightening the nut to the specified torque so the IP66 and IP69K seals seat correctly.

What part of this push button will need replacement after extended use?

The momentary contact block behind the flush head wears first; keep a spare ZB4 contact block on hand for quick swap without removing the metal operator.

Which environmental limit is reached first during continuous operation in a wash-down area?

The IP69K rating covers high-pressure hot water, but sustained exposure above the IEC 60068-2-27 shock and IEC 60068-2-6 vibration limits will degrade the metal bezel seal before the IP66 rating is exceeded.
