ST450-N Electric Skylight Actuator 300mm Stroke Adjustable Bracket 45kg Load

Product Overview

The ST450-N electric actuator is designed for automating the opening and closing of skylights and roof windows in commercial and industrial buildings. With a load capacity up to 45 kg, it operates on 230 V AC and integrates magnetic limit switches and an overload cut-off for added safety. Installers benefit from its 300 mm stroke length and standard mounting brackets, suitable for a wide variety of window and skylight types.
