(4) see VAC M-sheet 3101; storage temperature inside cardboard packaging (5) Constructed, manufactured and tested in accordance with IEC60664-1:2007 Isolated wires are preferred. If isolated primary conductors are used, the isolation coordination is according to: Reinforced insulation, Insulation material group 1, Pollution degree 2, altitude ≤ 4000m and overvoltage category II. (6) The results are valid under following conditions: 55°C mean component ambient temperature by continuous operation (8760h per year); Environment condition: ground mobile, no dust or harmful substances, according to IEC61709; Fit equals one failure per 10^9 component hours. General description of sensor function: The Sensor is sensitive to AC and DC current and can be used for fault current detection in IC-CPD applications. The Sensor detects AC and DC fault currents according to IEC62752:2016. In the event of a DC fault current, PIN 3 will change it’s state from a low level (GND) to high impedance level. In event of an AC current fault, PINs 3 and 4 will change state from a low level (GND) to a high impedance level. Error conditions (e.g. an internal error) are signaled on PIN 1 (ERROR-OUT). Patents added on sheet 1. CN-21-290 Sheet 1, Sclear, pp and Screep, pp (Clearance, unisolated primary to primary) deleted. Minor change.
