By order of Schneider Electric Bulgaria and for the needs of the newly built vaccine factory "Biovet" in Razgrad, we started the assembly of 3 MDS x 4000 amperes, breaking current 70 kA. The cabinets and busbars used are from Schneider Electric's pre-tested Prisma-P system.
Each MDS is powered by two Masterpact MTZ-40 air circuit breakers, fed by a Canalis insulated busbar system. The consumers are supplied by 9 distribution columns equipped with NSX 100/630A MCCBs.
The input and output circuit breakers are equipped with electronic protection devices to measure electrical energy. A communication system has been implemented, allowing the status of circuit breakers and electricity consumption to be monitored by a SCADA operating system.
