Advantages through energy efficiency

Overview of the energy management process

We offer you a unique portfolio for efficient energy management in the industry – a process that is used to optimize the energy requirements. We divide operational energy management into the three phases: identification, evaluation and implementation, and support you with suitable hardware and software solutions in each phase of the process.

The new SIRIUS industrial control technology products can also significantly contribute to the energy efficiency of a plant. (seehttp://www.siemens.de/sirius/energiesparen).

With 3RM1 motor starters, control cabinets warm up less because power losses have been reduced by operation:

• Lower intrinsic power loss (than comparable motor feeders with thermal overload trip) by means of electronic current analysis
• Lower control circuit power losses (compared with conventional switching devices) as a result of electronic control of switching points
• Thanks to the above advantages, additional energy savings are possible because less cooling is required (and a more compact design is possible)

Product advantages

The SIRIUS 3RM1 motor starters offer a number of benefits:

• Greater endurance and reduced heat losses thanks to hybrid technology
• Less space required in the control cabinet (20 to 80%) as a result of greater functional density
• Less wiring and testing required as a result of integrating several functions into a single device
• Lower costs for stock keeping and configuration as a result of the wide setting range of the electronic overload release (up to 1:5)
• Fast wiring without tools for rigid conductors or conductors equipped with end sleeves thanks to push-in spring-type connections
• Safety-orientated shutdown in accordance with SIL3/Ple by shutting down the control supply voltage without additional devices in the main circuit
• Motor status feedback to the higher-level control system in the case of 3RM10 and 3RM12 motor starters in the 24 V DC version
• Virtually error-free wiring on the mains connection side and reduction in short-circuit protective devices by means of 3RM19 infeed system
• ATEX certification: "Increased safety" type of protection EEx e according to ATEX Directive 94/9/EC (3RM1 motor starters in the safety version are suitable for overload protection of explosion-proof motors with "increased safety" type of protection EEx e)
