Interruptor rotativo Siemens 3SU1150-0AB20-1CA0 SIRIUS ACT, 22mm, 2 posições, 1NO, preto

The Siemens 3SU1150-0AB20-1CA0 is a robust 22mm selector switch from the SIRIUS ACT series, engineered for reliable control in industrial environments. Its latching 2-position operation with a 90° switching angle ensures precise, tactile actuation for machine control panels, conveyor systems, and automation tasks. The black actuator and silver front ring provide clear visual status, while the IP66/IP67/IP69K front protection makes it suitable for demanding washdown applications.

Advantages

This selector switch offers exceptional durability and ease of installation. The screw terminal connection allows secure wiring without special tools, and the modular design supports quick replacement of contact blocks. The high degree of front protection (IP66, IP67, IP69K) and NEMA ratings (4X, 12, 13) ensure resistance to dust, water jets, and temporary submersion, reducing downtime in harsh conditions. Its compact 22mm mounting diameter fits standard panel cutouts, and the plastic enclosure provides electrical insulation and corrosion resistance.

Suitable for

• Machine tool control panels requiring manual mode selection
