October 10, 2014 - Siemens adds size S2 Sirius switching, protecting and monitoring devices. S2 has a compact width of just 55 mm, a power rating of up to 37 kW, as well as a current rating of 80 A. The devices are thus especially space-saving in the control cabinet, meeting the requirements of modern plant engineering and mechanical engineering for components with minimum space requirements.
The same accessories used on the sizes S00 and S0, introduced in 2009, can also be used for the new size S2. The devices can be connected to the open systems AS-Interface and IO-Link simply via the plug-on function modules. Direct monitoring and control of the application are possible using the current monitoring relay that can be integrated into the feeder. The function modules for logic avoid intensive wiring effort, and simultaneously reduce the risk of wiring errors. Thanks to these function modules, and the possibility of integrating current monitoring directly in the feeder, the devices can be integrated easily into the automation environment, such as Totally Integrated Automation (TIA). Approximately 45,000 type-tested combinations enable simple configuring of the components. The individual devices can be combined as desired and thus flexibly assembled. They are available throughout with screw-type connections and spring-loaded connections, both in the main circuit and in the control circuit. From size S2, spring-loaded connections are offered in the control circuit only, due to the high current. The latest generation of the Sirius modular system is equipped throughout for conversion to the new IE3 motor generation. Thanks to global approvals, the devices can be used anywhere, and they comply with all the necessary standards. Siemens AG (Berlin and Munich) is a global technology powerhouse that has stood for engineering excellence, innovation, quality, reliability and internationality for more than 165 years. The company is active in more than 200 countries, focusing on the areas of electrification, automation and digitalization. One of the world's largest producers of energy-efficient, resource-saving technologies, Siemens is No. 1 in offshore wind turbine construction, a leading supplier of combined cycle turbines for power generation, a leading provider of power transmission solutions and a pioneer in infrastructure solutions and automation and software solutions for industry. The company is also a leading supplier of medical imaging equipment – such as computed tomography and magnetic resonance imaging systems – and a leader in laboratory diagnostics as well as clinical IT. In fiscal 2013, which ended on September 30, 2013, revenue from continuing operations totaled €75.9 billion and income from continuing operations €4.2 billion. At the end of September 2013, Siemens had around 362,000 employees worldwide on the basis of continuing operations.
