The Eaton Z-S230/S is a compact, heavy duty, single phase, 27KVA voltage selector switch designed to isolate, step-up/step-down, and/or reverse phase electricity. It offers a rugged, mechanical design with an integral spring mechanism on a stainless-steel flat plate to prevent over-pressure and thermal overload, making it suitable for harsh industrial and outdoor environments. The switch features two selector handles and two, three-position switches for phase-reversal, step-up/step-down and isolation functions. The switch is enclosed in an outdoor-rated NEMA 4X stainless steel enclosure for weather-resistant performance, providing protection from dust, dirt, moisture and other environmental elements.
