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