Energy-efficient control technology:
SIRIUS brings down energy costs

Energy management in industry

Overview of the energy management process

Be it for plant operators, planners or machine manufacturers: energy-efficient production is a challenge and an opportunity in equal measure.

Energy-efficient production as a success factor

To utilize potential energy savings, we always keep an eye on the entire product development and production process with our comprehensive portfolio. This is because only a perfect interplay of all components results in highly energy-efficient production.

To achieve this, it is important to first create an awareness of existing energy saving potential, to identify optimization options with the aid of a detailed analysis and to evaluate them. Finally, appropriate measures must be implemented (realized).

With our integrated portfolio of energy-efficient drive solutions, automation systems and services, you will also achieve maximum energy efficiency, higher productivity and sustainable competitive advantages in your enterprise.

The three columns of energy efficiency with SIRIUS innovative products

Energy-efficient products – SIRIUS reduces power loss

3RR2 monitoring relays, 3RB3 overload relays, 3RT2 contactors, 3RW soft starters, 3RV2 motor starter protectors and 3RA6 compact starters

SIRIUS Innovations controls are distinguished by extremely low inherent power loss. This cuts not only energy costs, but also the amount of waste heat in the control cabinet. This then translates to a higher packing density and a reduction in the required cooling performance.

Energy-measuring products

SIMOCODE pro 3UF7 motor management and control device, 200D motor starter, ET 200S High Feature direct-on-line starter

Energy management can be instrumental in increasing plant productivity and thus bringing about a significant improvement to the competitive ability of a company – in all areas of industry.

Communication-capable SIRIUS switching and protection devices provide measured energy data without additional installation complexity.

Energy-Optimized Drive Solutions

To optimize energy efficiency of processes, it is not only important to measure the energy flow and to use energy-efficient products. An exact consideration of the application provides the greatest leverage for saving energy:

SIRIUS supports you where UL is concerned.

SIRIUS application areas

We support you where UL is concerned

Product liability laws in the USA are significantly stricter than in Europe. Anybody wishing to export their products to North America is strongly advised to have them certified to UL standards, particularly where electrical equipment is concerned. We can help you with our comprehensive know-how and broad portfolio of UL-certified low-voltage controls.

Who or what is UL?

UL (Underwriters Laboratories Inc.) is one of the world's leading organizations involved in product safety testing and certification. This independent, non-profit making US-based organization was founded in 1894 by American fire insurance groups, with the intention of investigating the fire hazards presented by electrical devices.

Today, UL checks and certifies the operational safety of all kinds of materials, components and end products, particularly with regard to the possibility of personal injury and the formation of fires. There are branches in a number of European countries. You can find more detailed information about this American organization, as well as how to get in touch with the numerous branches throughout Europe, on the Internet at

Differences between UL and IEC

The IEC standards for the IEC market merely define the minimum safety requirements for a device or system. The technical details relating to how safety requirements are to be implemented in practice a matter for the manufacturer.

By contrast, the guidelines for the American market are much more specific. Depending on the standard, the entire process in question may be monitored - from product design and manufacture to application and installation, right through to operation.

NFPA79 is the electrical standard for industrial machinery outside the control cabinet. As such it differs from and is the counterpart to the control cabinet standard UL 508A.

A UL partner since 1969

Enlisting the expertise of a partner such as Siemens is a wise move for anyone who wishes to avoid unnecessary aggravation and save both time and money.

Ever since 1969 our production facility in Amberg, where our entire range of low-voltage controls is developed and produced, has been working closely with Underwriters Laboratories Inc.

Right from the product development stage, we take not only EU Directives and IEC guidelines, but also UL standards, into account. This has resulted in a wide-ranging portfolio of UL-certified low-voltage switchgear, controlgear and protection circuit technology.

We therefore offer comprehensive know-how on the subject of UL certification, ranging from production down to control panel wiring according to UL standards, which we will be pleased to explain to you within the scope of our application consulting service.

Our range of low-voltage controls keeps you on the safe side where UL is concerned, and allows you to assemble UL-compliant control cabinets quickly and easily.
