SIRIUS ACT knob switch for switching and controlling electrical consumers. Under the brand name SIRIUS ACT, Siemens offers a unique portfolio of control and signaling devices with worldwide product approvals in three modern design series made of robust real metal and high-quality plastic. The innovative snap-on concept simplifies installation to the extent that only one hand and no special tools are required. For mounting holes, non-threaded holes are sufficient, as a 100% anti-rotation protection is already integrated. Thanks to the consistently high protection class, the robust devices are industrial-grade and suitable for outdoor use. Even cleaning with high-pressure jets is possible. Neither dust, oils, nor aggressive alkalis can disrupt reliable operation. In addition to standard wiring, most devices can also be connected to the control system via PROFINET, AS-Interface, or IO-Link. This reduces your wiring effort, minimizes sources of error, and provides greater flexibility. The graphical online configurator comfortably supports the selection and ordering of individual devices, enclosures, and labels. Extensive documentation (e.g., manual, 3D data, connection diagram) is available. Available versions: multiple colors, 2-4 switching positions, short/long knob or rotary knob, illuminated/non-illuminated (illumination can also be retrofitted), latching/tactile operation. Note: Individual device, holder, and modules must be ordered separately. SIRIUS ACT - Performance in Action for commanding and signaling. Easily mounted, simply strong, simply perfect.
