Main Applications

Linear Open Loop current sensors with 3 series and 2 derivations for a total of 25 models.

  • Primary nominal current 50-800A
  • L03S***D15WJ/WM
    - Primary nominal current 50-800 A. Wider Saturation – 2 connector types – Horizontal connector orientation
    L03S***D15
    - Primary nominal current 50-600 A – Vertical connector orientation.

    Note: Models with wider saturation current should not be attached directly to the bus bar

  • Maximum dimensions/through hole dimensions of each series are compatible designed.
