30 mm Red Emergency Stop Operator

The Eaton HT8AERB is a 30 mm mushroom-head push button built for industrial control panels. It provides a single normally-closed contact rated at 10 amps and 600 volts AC for emergency-stop or safety-interlock circuits. The red anodised-aluminium bezel and metal head meet NEMA 1, 2, 3, 3R, 4, 4X, 12, 13 and IP66 ratings, so the device suits wash-down and outdoor enclosures. Panel builders who need a compact, standards-compliant e-stop will find it matches the cut-out and legend requirements of many Allen-Bradley compatible panels.

Sealed Construction for Harsh Environments

The IP66 and NEMA 4X ratings mean the operator resists high-pressure water jets, coolant spray and corrosion without extra gaskets. Screw-clamp terminals accept solid or stranded wire directly, reducing wiring time and eliminating loose-crimp failures in vibration-prone machinery. Momentary action returns the contact to its closed state automatically when the 40 mm mushroom head is released, giving a predictable reset for safety circuits. No internal illumination or electronics are present, so there is no heat dissipation or electrical noise to manage.

Panel Integration and Compatibility

The 30 mm mounting diameter fits standard industrial push-button cut-outs, and the anodised aluminium bezel matches common panel finishes. One operator occupies a single station, leaving adjacent positions free for indicator lights, selector switches or additional e-stops. CSA and UL listings simplify control-panel certification for North American installations. Buyers who require a normally-open contact, a maintained-pull-to-release action, or an illuminated head will need a different operator model.

Questions about this item

How do I mount the 30 mm mushroom head operator into a panel cut-out?

Insert the operator through the 30 mm panel hole, orient the metal mushroom head and anodized aluminium bezel, then tighten the locking nut from behind until the IP66 seal seats evenly.

What parts will need replacement after extended service?

The screw-clamp 1NC contact block rated 10 A at 600 V AC and the momentary-action mechanism are the wear items; the metal head and bezel typically outlast them.

Which environmental limit is reached first during continuous operation?

The contact rating of 10 A at 600 V AC defines the electrical ceiling, while the IP66 and NEMA 4X enclosure ratings set the ingress boundary.
