Over the last decade, medium voltage distribution networks have experienced significant changes. The new energy distribution philosophy, so called Smart Grid, has changed network's needs and solutions. Innovative solutions are required to satisfy these new demands. The so called integrated circuit breaker (iCB) series, has been specifically developed to enable easy, flexible and reliable medium voltage switchgear engineering and operation. Thanks to the sensors and the Intelligent Electronic Device (IED) integrated on board; the iCB combines measurement, protection and control capability with the primary power disconnection, switching and interruption technology. The IED has been designed to unleash the full potential of the IEC61850 standard for communication and interoperability. The entire switchgear life cycle is optimized by the adoption of the iCB. Starting from the easier specification and ordering, to the drastically reduced complexity of the switchgear in terms of engineering, wiring and testing, commissioning and maintenance of the panel. The MV iCB simplifies the connection of the private networks to smart grids with higher reliability, safety and at lower cost for the whole installation.
