Note : 1. 1 phase 2wire and 1 phase 3wire devices are set for a frequency of either 50Hz or 60Hz. 3phase line devices can operate at either 50Hz or 60Hz. 2. It is necessary to balance the voltage circuits of 3phase 3wire devices. However, the current will behave normally if the circuits are not balanced.

※Power factor measurement in circuits that have tidal currents
The effectuve measurement range of NHP type power factor transducers is LEAD 0.5～1～LAG 0.5.
Does not operate normally during backward tidal current(the current supply and receeipt flow are reversed).
※When items from the NHP series are removed from their sockets,to prevent the input circuits from remaining open
a protector(diode unit ZHP－B)is fitted.
Inform us if this is not required.
※For special specification above contact a company representative.
