General standards for current transformers:

• Type of isolation: E
• The maximum operational voltage is < 0.72 kV, and the nominal frequency is 50Hz (alternative frequencies can be requested).
• Thermal short-time current nominal: Ith = 60 x In
• FS 5 serves as the over-current limiting factor up to 1500 A nominal current.
• MBS AG current transformers fully abide with: IEC 61869/1+2 - VBG 4 - DIN 42600 - DIN VDE 0414/1
