NZR Current Transformer TK30 250/5A: additional details
The TK series current transformers are inductive, single-phase 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 TK series is suitable for mounting on both insulated and non-insulated primary conductors.

Current transformers for low-voltage installations (DIN EN 60044/1, DIN 42600, DIN VDE 0414/1), suitable for retrofitting without opening the circuit, core can be opened with a snap closure, frequency from 50 to 60 Hz, for secondary currents of 5 A, operating voltage up to 720 V, accuracy class 1 in accordance with IEC 1036, temperature range from -5 to +40 °C, for mounting on busbars and cable conduits.

TK30, primary current up to 250 A, secondary current 5 A, internal dimensions (H x W) 30 x 20 mm, external dimensions (H x W) 106 x 93 mm, depth (D) 34 mm, class 1, burden 1.5 VA. EAN: 4048652002870.
