Siemens Enables Holistic Energy Data Analysis in Buildings

Siemens Enables Holistic Energy Data Analysis in Buildings

At this year’s Light+Building trade show, Siemens Smart Infrastructure will show the first energy management solution that holistically captures energy data in buildings. It collects data all the way to the final circuit without any additional wiring or space requirements. All electrical data – from the power feed-in to the socket outlet – can then be seamlessly integrated into building management systems and analyzed by cloud-based applications.

Phoenix Contact CBM Circuit Breakers with Nominal Current Wizard

Phoenix Contact CBM Circuit Breakers with Nominal Current Wizard

 

Four to eight channels can be safely protected against overload and short-circuit currents with the CBM multi-channel circuit breakers. Thanks to the integrated nominal current wizard, setting the right nominal current for your loads is easy.The selected settings are locked electronically. This prevents the risk of unwanted incorrect settings.

The integrated early warning system ensures fewer failures. When the set nominal current of a channel reaches 80%, a warning is issued via the associated LED. Furthermore, the separate signal output can be used for remote signaling. 

 

Siemens IEC Miniature Circuit Breaker

Siemens IEC Miniature Circuit Breaker

 

IEC style miniature circuit breakers (MCB), according to ENNEC 60 898, are not always permitted in North America. For this reason, MCBs were developed that were based on the miniature circuit breakers of the 5SY series and met the special requirements of UL 489. Within the sphere of influence of NEMA (National Electrical Manufacturers Association) and ANSI (American National Standards Institute) MCBs are certified as a solution for protective applications and can be used for branch circuit protection in the branches of control panels and systems.The connection terminals are designed for the class: “Field wiring”.
