L03S Family

caraL03S Family

Linear Open Loop current sensors with 3 series and 2 derivations for a total of 26 models.

Succession model ‘s number:L37SxxxD15x series

- Rated Current 50-800 A. Wider Saturation – 2 connector types – Horizontal connector orientation
- Rated 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.
