Siemens 52SA2AABA1 Oil Tight Selector Operator

Siemens 52SA2AABA1 is a heavy-duty 30 mm panel-mount selector switch designed for rugged industrial use in water- and oil-tight environments. This two-position, maintained (non-spring-return) operator uses a short lever and A cam to deliver 1NO-1NC (DPST) contacts in a non-illuminated head with a white insert, suitable for on/off style switching in control panels. It is rated for up to 60 A at 110 V AC and UL-listed under file E22655, making it a robust choice for higher-current circuits. Built for harsh conditions, the unit offers ingress protection at IP66 when installed in appropriate enclosures and environments, and it operates across a wide temperature range from -35°C to 70°C. The 52SA2AABA1 variant is specifically a metal-bodied, oil-tight, water-tight selector switch with Maintained operation and a compact footprint that fits standard 30 mm mounting bays, making it a common selection for industrial equipment such as conveyors, machine controls, and power-distribution panels where a reliable two-position selector is required.
