The Siemens Building Technologies Division has expanded its offering of Sivacon S8 low-voltage switchboard assemblies by adding new panel types and modules which enable even greater flexibility and efficiency for the configuration of power distribution in industrial plants.
The new additions include a panel with universal installation system and an optimised ventilation concept, a panel for the integration of up to three air circuit breakers, and an active filter module for network quality enhancement. The new switchboard assemblies will be presented at Hanover Fair 2011.
The circuit breaker panel of the Sivacon switchboard assembly was expanded in order to increase the packing density. As the result it is now possible to install up to three air circuit breakers 3WL from Siemens in one panel and to combine them flexibly as required.
With type tested standard modules, Sivacon switchboard assemblies guarantee efficient power distribution in industrial applications and provide for a high level of operator and plant protection.
The new universal installation panel permits the space-optimised integration of unit combinations for motor controls, safety relays and frequency converters in withdrawable design or fixed-mounting technology.
The rack units contain the latest Sirius switching and protection devices, Sinamics frequency converters, and the Simocode pro motor management system from Siemens. The fail-safe expansion modules, which are part of Simocode pro, enable the safe shutdown of motors in process automation.
Simocode can be connected through Profibus to higher-level automation systems and unites all essential protection, monitoring and control functions for each motor feeder in a single system. In addition the switchgear panel has its own ventilation system which can be connected to a heat exchanger or a building air conditioning system in order to make further use of the hot air produced in the system.
The cold air, which enters the switchgear panel via ventilation slots, is directed by a new integrated ventilation duct along a defined route through the inside of the panel and the heated air is then discharged in upwards direction from the left side of the panel.
