30 mm Red Mushroom-Head Push Button
The Eaton HT8CBRB is a 30 mm mushroom-head push button with a maintained action and a red 40 mm metal operator head. It carries a single normally-closed contact rated at 10A @ 600V AC and is built for industrial control panels and automation equipment. The anodized aluminium bezel and metal construction suit harsh environments where reliable emergency-stop or manual-control functions are required.
NEMA and IP ratings define the environmental limits
The operator meets NEMA 1, 2, 3, 3R, 4, 4X, 12 and 13 ratings and an IP66 ingress-protection rating, so it withstands dust, water jets and corrosion in indoor or outdoor installations. The screw-clamp terminals accept standard wiring for the A600/P600 contact rating, but the device provides no legend plate and no additional contact blocks beyond the single 1NC circuit. Buyers who need illuminated operators, multiple contacts or a different colour must select another model.
Panel mounting is straightforward
The unit fits a standard 30 mm panel hole and secures with the supplied mounting hardware; screw-clamp terminals simplify field wiring without special tools. The maintained-action mechanism stays in the pressed position until manually reset, so operators must verify the reset procedure matches their safety-circuit logic. Miswiring the single normally-closed contact or omitting a required legend plate are the most common installation errors.

Questions about this item
Should I choose the 30 mm mushroom-head operator or a smaller flush button for my panel?
The 30 mm mushroom head gives a large 40 mm domed target that is easy to locate and actuate with gloves, while a flush button would need a smaller cut-out and offers less tactile area.
What does the 10 A, 600 V AC rating mean when the button is wired into a control circuit?
It means the single normally-closed contact can safely break or make up to 10 amps at 600 volts AC, matching the A600/P600 NEMA designation for heavy-duty pilot-duty loads.
The screw-clamp terminals accept what wire sizes and how does the IP66 rating hold up in practice?
The screw-clamp terminals are designed for standard industrial control wiring; the IP66 and NEMA 4X ratings mean the operator resists powerful water jets and corrosion when mounted in a properly sealed enclosure.
