Schneider Electric ZB4BC6 Blue Mushroom Head

The Schneider Electric ZB4BC6 is a 22 mm blue mushroom head push button operator designed for industrial control panels. It features a momentary action with a 40 mm metal head, metal bezel and metal base construction. The unit carries NEMA 1, 2, 3, 4, 4X, 13 ratings and IP66, IP67, IP69, IP69K ingress protection for harsh environments.

Suited for panels needing a robust momentary

This operator fits panels cut for a 22 mm mounting hole and serves applications requiring a large, colour-coded emergency or control actuator. It is not suitable for maintained or latching functions, nor for installations that require a smaller flush head or a different colour code. Buyers needing a key-release or twist-to-release mechanism should look at alternative operator types.

Mounts in a standard 22 mm cut-out

The all-metal construction withstands wash-down and outdoor exposure thanks to the high IP and NEMA ratings. It requires a compatible contact block and mounting collar sold separately to complete the circuit. The 40 mm mushroom head provides a large target for gloved operation while the momentary action returns automatically when released.

Questions about this item

Does this push button need a specific contact block or mounting adapter to work?

It requires a compatible 22 mm contact block and mounting collar that match the operator's metal bezel and momentary action.

Will the 22 mm mounting fit the same panel cut-out as my older 22 mm operators?

Yes, the 22 mm size matches the standard cut-out used by legacy Schneider Electric 22 mm operators, so existing panel holes align.

How can I verify the IP66, IP67, IP69 and IP69K seals are intact after installation?

Inspect the blue mushroom head and metal bezel for damage, then confirm the NEMA 1, 2, 3, 4, 4X and 13 ratings by checking that the gasket seats evenly in the panel.
