Appleton™ WST and WDS Cast Aluminum Enclosed Disconnect Switches

Appleton

Appleton™ WST and WDS Series cast aluminum enclosed disconnect switches are designed for applications where a heavy duty switch is required. Their gasketed design allows them to be used for raintight or watertight nonhazardous applications. The WST 600 Vac or 600 Vdc and WDS 600 Vac units are available in 30, 60 and 100 Amp, fused and non-fused models. They are used to control power to fixed electrical equipment such as welders, generators, compressors, infrared ovens, batch feeders and conveyors.
