NZR Current Transformer 42600300: further details
Current transformers of the TQ series are inductive, single-conductor current transformers operating on the transformer principle. They are used to adapt the primary measurement quantity to the input rated values of the connected measuring devices. Due to the applied measurement principle, these current transformers are suitable for exclusive use in alternating current networks. The TQ series is only suitable for installation on insulated primary conductors. The TQ30 is only suitable for use in a weather-protected and dry location on insulated primary conductors.

Current transformers for low-voltage systems according to IEC61869-2, suitable for retrofitting without breaking the circuit, operating temperature range -10 °C to +55 °C, ambient conditions 5% to 85% relative humidity, no condensation, protection class IP20, thermal short-time current 60 x In/1s, thermal continuous current 100%, maximum operating voltage 0.72 kV, insulation test voltage 3 kV, rated frequency 50/60 Hz, insulation class A (105°C), cable opening for conductors up to Ø 18 mm, secondary connection fixed wired cable, 3 m, 0.5 mm², for installation only on insulated conductors.
