Protection of the Voltage Measurement Inputs and the Supply Voltage of the PAC3100, PAC3200 and PAC4200

  • Entry
  • Associated product(s)


Why has there been a change of the prescribed conductor protection for the voltage measurement inputs and the supply voltage of the PAC3100, PAC3200 and PAC4200?


Inspections have shown that fuse protection for the measurement voltage inputs and power supply is sufficient for the PAC3100, PAC3200 and PAC4200 devices.

The conductor protection for the device supply and the measuring voltage inputs has changed as follows. DE ** fuses are used for conductor protection, max. 16 A (C) or 20 A (B).

Thus, a commercially available conductor protection product can be used up to the specified max. value.
