General standards for current transformers:

• Category of isolation: E
• Maximum operational voltage: < 0.72 kV
• Nominal frequency: 50 Hz (other frequencies upon request).
• For thermal short-time current, the nominal value is Ith = 60 x In.
• Up to 1500 A nominal current, the over-current limiting factor (FS 5)
• All MBS AG current transformers adhere to: DIN 42600, IEC 61869/1+2, VBG 4, and DIN VDE 0414/1
