Industrial Controls



Product Summary

Today's market demands unprecedented efficiency best found in products designed to be flexible and dependable. Siemens offers off-the-shelf hardware and software products that are easy to use and integrate within your existing design. From Soft Starters to Overload Relays, Siemens offers critical components or a total system solution that is the key to your long-term success.

Unsurpassed Control in any Industrial Environment One true measure of effective industrial performance is the ability of the technology you employ to produce real competitive advantages. With a comprehensive industrial control technology offering, Siemens provides just that at practically every level of your facility. Siemens continues at the forefront of power switching technology with a comprehensive line of NEMA, IEC and Definite Purpose controllers.

IEC Contactors

When endurance and extreme load capability are the name of the game, Sirius Contactors are the perfect choice. The narrow design, the high availability, and the wide range of Sirius contactors ensure that these contactors have the optimum type for any requirement. Standard Contactors, along with Vacuum, 4 pole, 4 pole (2 NO + 2 NC), Capacitive, Standard Reversing Contactor Assemblies, Resistive, Solid State or Conventional Coil, with Remaining Life Time indicator, with AS-Interface are just a few of the versions which round out the Sirius Family. A large array of easily installed, standard accessories may be used to customize the contactors for different applications. These auxiliaries can be easily connected to the family of contactors. High contactor reliability, long life time, and the ability to operate under extreme conditions (up to 60 degrees C) differentiate the Sirius family of contactors.


Siemens is leading the industry with the largest selection of NEMA Starters. Typical applications include use with machine tools, air conditioning equipment, material handling equipment, compressors, hoists and various production and industrial equipment, as well as in demanding automotive applications. NEMA starters are ideal for applications requiring dependability and durability. These starters are built rugged to withstand the most severe and demanding industrial and continuous duty commercial applications in the industrial and construction markets. This includes standard full NEMA sizes and motor matched half sizes exclusive to Siemens. Starters are available as open and enclosed with electronic and bimetal overload protection, as well as a wide selection of accessories and spare parts.

SIRIUS IEC Motor Starter Protectors

3RV10 Motor Starter Protectors (MSPs) are built for a wide range of applications and meet the requirements of control users worldwide. Each MSP features a manual ON/OFF switch, a Class 10 adjustable bimetallic overload relay (Class 20 available in the two largest frame sizes), and magnetic trip elements for short circuit protection.


A gentle approach is always the best... Nowadays, three-phase motors represent the most favored type of drive concept. Direct starting or star-delta starting is, in many cases, not the best solution. Such methods often result in unpleasant side-effects such as mechanical impacts inside the machine or voltage dips in the power supply system. Our new SIRIUS family of soft starters is a comprehensive range of products covering all the standard and high-feature motor-starting applications. The advantages of soft start-up and smooth ramp-down with these devices can therefore be exploited in the most varied of applications for simple and economically efficient machinery and equipment layouts.

SIRIUS IEC Overload Relays

SIRIUS overload relays are available in thermal and solid-state versions. The can be directly mounted to SIRIUS 3RT contactors and 3RA reversing contactors or separately mounted in the control panel. 3RU1 thermal and 3RB20/21 solid-state versions provide current-dependent overload protection of motor loads. The modular 3RB22/3RB23 solid-state overload relays offer a higher level of functionality and protection. These devices not only protect your loads as a function of the current, but also as a function of the temperature when a PTC thermistor sensor is connected. The PTC sensor directly measures the temperature of the motor windings which is then evaluated by the relay.

Push Button and Pilot Devices.

Siemens offers an extensive array of pilot devices and signal columns for a wide variety of applications. Pushbutton and pilot device offerings include: • 16mm 3SB2 series for applications where panel space is a premium • 22mm 3SB3 series offers maximum flexibility and industry best time install savings and environmental ratings. Networked control stations offer state of the art technology including certified networked safety combinations. • 30mm Class 52 series is the classic pushbutton design for the NEMA markets. Offering both standard die cast metal and the ultra rugged BLACK MAX styles, you can feel confident using the best pilot devices available • NEMA 7 & 9 Hazardous location and standard duty control stations round out the complete lineup of pilot control components

Signal Columns & Beacons

8WD4 Signaling Columns and Beacons—The smart, modular light pole As automation has evolved in industrial and commercial settings, so has the need for enhanced communication between the automated process and its user. This need has spawned a multitude of signaling columns-none as refined as the 8WD4 Series from Siemens. The 8WD4 Series consists of two product lines: the popular 8WD43 and the compact 8WD42. Within each line, there exists a host of light, color, sound and mounting options. You tailor your 8WD43 or 8WD42 to the system or process you wish to monitor. This versatility lends itself to a broad range of applications.
