Siemens Furnas 52SB2CAB 3 Position Long Lever Selector Switch

Siemens Furnas 52SB2CAB is a 30 mm panel-mount selector switch operator designed for rugged industrial control panels, with a standard cutout size that fits a wide range of DIN-rail and panel-mount enclosures. This three-position, maintained, non-illuminated unit features a long lever, a white insert, and a C cam, and is sold as an operator-only component intended to partner with Furnas Class 52 contact blocks to form a complete, field-serviceable selector switch. The assembly uses a metal bezel and housing for durability and carries UL file E22655, underscoring its suitability for commercial and industrial electrical installations that require reliable position selection in harsh environments. As part of the 52-class family, it is commonly stocked by distributors and widely referenced in official catalogs and listings, used in motor starters, conveyors, packaging lines, and process equipment where a simple, robust three-position control with non-illuminated indication and easy integration into existing control panels is essential.
