General data

● Plastic case and insulating resin are self-extinguishing.
●  Two fixing modes:
  ●  Horizontal or vertical with fixing holes in the case moulding.
  ●  By bar using the intermediate flange kit (Refer to accessories and options on the following page).
●  Max tightening torque for M6 screws (flange mounting): 2 N.m
●  Direction of the current:
  ●  Output current (IS1 and IS2): A primary current flowing in the direction of the arrow results in a positive secondary output current on terminals IS1 and IS2 .
  ●  Output voltage (VS1 and VS2): A primary current flowing in the direction of the arrow results in a positive secondary output  voltage on terminals VS1 and VS2 .
●  Burn-in test in accordance with FPTC 404304 cycle.		Primary connection

Hole for primary conductor.
The temperature of the primary conductor in contact with the case must not exceed 100°C.


Secondary connection
● Male straight 8 pin connector (integrated in the sensor) A female straight 8 pin connector is provided as standard with each product.

● Shielded cable 6 x 2000 mm (cross section 0.5 mm2).
