Technical characteristics
| Secondary | 5 A |
|---|---|
| Mains voltage | ≤ 660 V · 50 / 60 Hz |
| Rated voltage | ≤ 660 V |
| Type | Current transformer with through-type primary1 |
| Rated current | Primary 30 – 1.000 A · secondary 5 A · Ith 60 × In1 |
| Accuracy class | 0.5 or 1 depending on the ratio1 |
| Primary | Cable or bar passing through the CT window |
|---|---|
| Mounting | Window for cable or bar · mounting on plate or DIN rail2 |
| Standard | IEC 61869-2 |
|---|
| Selection | Ratio ≥ rated current of the outgoing circuit; CT burden ≥ device consumption + secondary wiring losses |
|---|---|
| Safety | Never open the secondary under load: short-circuit terminals S1–S2 before disconnecting the instrument |
