The key features and benefits of the 3RB22 and 3RB23 electronic overload relays are detailed in "Overload relay" > "Overview" in PDF form.

Overview of the energy management process

Advantages through energy efficiency

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 controls can also make a major contribution to the energy efficiency of a plant (see http://www.siemens.com/sirius/energysaving).

3RB22 and 3RB23 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
