Siemens 3SB18 Enclosure

Siemens 3SB18 Enclosure is a plastic enclosure in the SIRIUS ACT family designed to house 22 mm pushbutton units and indicators for panel-mounted control stations. A common variant is 3SB18-01-8AA, illustrating the standard plastic enclosure used with Siemens 22 mm control elements to create compact operator interfaces in industrial equipment. This enclosure, formed from durable plastic, is intended to mate with Siemens' 22 mm SIRIUS ACT devices, providing a ready-made housing that supports clean wiring, easy labeling, and repeatable panel installations. Suitable applications include control stations, start/stop panels, and other localized operator interfaces where Siemens 22 mm pushbuttons and indicators are deployed.
