General data Primary connection
– Plastic case and insulating resin are self-extinguishing Hole for primary conductor.
– Two fixing modes: The temperature of the primary conductor in contact with the case
- Horizontal or vertical with fixing holes in the case moulding. must not exceed 100 °C.
- By bar using the intermediate side plate kit (Refer to Accessories
and options on the following page).
– Max tightening torque for M6 screws (side plate mounting): 2 N.m Secondary connection
– Direction of the current: – Male straight 8 pin connector (integrated in the sensor)
- Output current (I S1 and I S2): A primary current flowing in the A female straight 8 pin connector is provided as standard with each
direction of the arrow results in a positive secondary output cur- product
rent on terminals I S1 and I S2. – Shielded cable 6 x 2000 mm (cross section 0.5 mm²).
- Output voltage (V S1 and V S2): A primary current flowing in the
direction of the arrow results in a positive secondary output volt-
age on terminals V S1 and V S2.
– Burn-in test in accordance with FPTC 404304 cycle
