Product Identity

The Eaton M22S-R30 adapter ring set converts 30 mm panel cut-outs to accept 22 mm M22 push-button operators. It is intended for control-panel builders and maintenance engineers who need to fit standard 22 mm devices into larger openings without replacing the enclosure.

Build and Mounting

Each ring is moulded in black thermoplastic and snaps into the 30 mm hole, providing a flush, secure seat for the 22 mm actuator. The set supplies enough rings for multiple conversions, so installers can complete a panel row in a single session without sourcing additional hardware.

Critical Specification

The adapter bridges a 30 mm cut-out down to 22 mm, matching the Eaton M22 series mounting standard. Panels drilled for any other diameter will not accept these rings, and 22 mm devices from incompatible series may not latch correctly.

Questions about this item

What hole sizes does the Eaton M22S-R30 adapter ring convert between?

The set converts a 30 mm panel cutout down to 22 mm so standard M22 push buttons can be mounted.

What panel thickness or cutout preparation does the adapter ring require?

It fits a 30 mm diameter cutout; the ring seats against the panel surface and secures the 22 mm device from the front.

How is the adapter ring installed and what step is often missed?

Insert the ring into the 30 mm hole, place the M22 operator through the 22 mm centre, then tighten the operator's locking nut — forgetting the nut leaves the assembly loose.
