Measuring Current Transformer TK40 - TENSE

Product Description:
The TK40 current transformer is designed for indirect AC current measurement in low-voltage installations and industrial applications. The transformer converts large primary currents into standard secondary currents suitable for measurement, control, or equipment protection.

Features:

  • Accurate current conversion with 0.5S accuracy class.

  • Compact and durable housing made of non-flammable, fire-resistant ABS.

  • Terminal block with non-removable cover, suitable for large wires.

  • Short-circuit current resistance: Ith = 60 × In

  • Continuous current resistance: Id = 1 × In

  • Operating temperature: -25 °C ... +85 °C

  • Installation: KK0001 or KK0002

  • Test voltage: 3 kV for 1 minute

  • Maximum system voltage: 0.72 kV
