Green Mushroom Push Button 22 mm

The Schneider Electric ZB4BR3 is a 22 mm mushroom-head push button with momentary action. Its green metal head and metal bezel mount in a standard panel cut-out. Rated IP66 and NEMA 1, 2, 3, 4, 4X, 13, it suits industrial control panels that need a distinct, colour-coded operator. The unit carries IEC 60947-5-1, UL 508 and other listed approvals.

Replacing worn or mismatched operators

Swap this button when an existing 22 mm operator is damaged, faded or the wrong colour for the safety scheme. The momentary function matches standard start, reset or jog circuits. The jump is worth it when the panel demands IP66 sealing and metal construction for harsh environments. It is not for applications needing maintained latch action or illuminated heads.

Verify panel cut-out and control voltage

Confirm the enclosure provides a 22 mm mounting hole and that the contact block behind the operator matches the circuit voltage and current. Check that the NEMA and IP ratings meet the enclosure specification. Ensure the green colour complies with the site wiring or safety standard. The device is REACH and RoHS compliant.

Questions about this item

What panel cut-out diameter does the 22 mm mushroom head require?

The operator is designed for a 22 mm panel cut-out, matching the standard mounting size for this series.

How is the momentary mushroom head secured during installation?

The metal bezel threads into the 22 mm cut-out and is locked with the supplied fixing nut; the common error is not tightening the nut to the specified torque.

Which components may need replacement after extended use?

The green mushroom head and internal contact block are the wear items; the metal bezel and mounting nut typically remain serviceable.
