Function and Application
The NLH2-0.8 series current transformers are suitable for indoor use, with a rated voltage of 0.8kV and below, and a rated frequency of 50Hz in AC circuits for current and energy measurement or metering. The product adopts an openable structure, allowing the installation or replacement of the transformer without removing the busbar.
