Switchgear and control gears of KRU-SESH-61M series are intended for receipt and distribution of electric energy of three-phase current with power frequency of 50 and 60 Hz with voltage 6(10) kV for currents 630-4,000 A. Lead-in cabinets and sectioning cabinets for currents 2,000-4,000 A KRU-SESH-61M are recommended to use in KRU-SESH-63 for input of high currents – more than 1,600 A. KRU-SESH-61M cabinets are joined with KRU-SESH-63 cabinets on the collecting buses without using junctions.
KRU-SESH-61M for NPP is intended for operation in a NPP system of class 20 (for emergency power supply systems) and 3H (for normal operation systems as per classification OPB-88/97 (PNAEG-01-011-97).
