22 mm Red Mushroom-Head Operator

This Schneider Electric ZB4BC44 is a 22 mm red mushroom-head push button designed for industrial control panels and automation cabinets. It provides a momentary contact action suited to emergency-stop or manual-override stations where a large, visible actuator is required.

Metal Construction and 22 mm Cut-Out

The operator body, head and bezel are all metal, so the device withstands mechanical shock and vibration in harsh environments. Installation uses a standard 22 mm panel cut-out; the only common issue is forgetting to order the matching contact blocks and mounting collar separately.

IP66 and NEMA 4X Under Continuous Use

Rated IP66 and NEMA 1, 2, 3, 4, 4X and 13, the seal maintains its ingress protection during prolonged exposure to water jets, dust and corrosive atmospheres. Compliance with IEC 60947-5-1, IEC 60947-5-5 and UL 508 confirms reliable operation over extended duty cycles rather than brief actuations only.

Questions about this item

How do I confirm the mushroom head push button is operating correctly after installation?

Press the red mushroom head and verify momentary contact closure; the metal bezel and head should return flush without binding, and the IP66 seal must remain intact.

What components are included with the ZB4BC44 and what must be sourced separately?

The operator ships with the 22 mm red mushroom head, metal bezel and metal head; contact blocks, legend plates and mounting hardware are not included and must be ordered separately.

Which version of the 22 mm mushroom head push button should I select for my application?

Choose the ZB4BC44 when you need a 30 mm diameter red metal mushroom head rated NEMA 1, 2, 3, 4, 4X, 13 and IP66 for momentary operation.
