ASK 41.4 Voltage transformers:

• The isolation class is E, the nominal frequency is 50 Hz (others upon request), and the maximum operating voltage is Um ≤ 0.72 kV.
• 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)
• The MBS AG current transformers completely comply with the following standards: VBG 4, IEC 61869/1+2, DIN 42600, and DIN VDE 0414/1.
• Class 1 (1A secondary) standard current transformers
