The key features and benefits of the 3RB30 and 3RB31 electronic overload relays are detailed in "Overload relay" > "Overview" in PDF form.

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).

3RB30 and 3RB31 solid-state overload relays contribute to the overall energy efficiency of a plant as follows:

• Lower intrinsic power loss
• Less heating of control cabinet
• Smaller control cabinet air conditioning units can be used
