Summation current transformers LU01


Designed to summarize several synchronous alternating currents of equal phase relation with any angle of phase dierence. They are used to add secondary currents of several main CT’s in order to measure with the CT only.

The output current again constitutes a standardized quantity. That means the primary currents are not only added but also divided by the number of inputs

  • Available current transformers versions with 2 to 8 primary windings.
  • Nickel plated secondary terminals with +/- screws.
  • Accuracy classes 0,5 & 1
  • Rated secondary output 5A
  • Maximum system voltage 720V
  • Multiple mounting methods, including wall mounting, DIN rail 35mm.
  • Terminal protection IP10.
