Advantages through energy efficiency
Siemens offers you a unique portfolio for efficient energy management in industry – a
process that serves to optimally shape your energy requirement. Operational energy
management is subdivided into three phases:
● Identifying
● Evaluating
● Realizing
Siemens supports you with suitable hardware and software solutions in every phase of a
project.

The 3RB30/3RB31 electronic overload relays make the following contribution to energy
efficiency in an overall installation:
● Reduced intrinsic power loss
● Reduced control cabinet heat development
● Smaller control cabinet air conditioning units required
