LEM ATO Series Split Core Current Transformer, 50A Input, 50:1, 10mm Bore

The LEM transformer is a split core current transformer with quick, non intrusive and easy setup with no interruption of electricity during installation on insulated conductors. ATO series is ideal for the electronic measurement of AC waveform current with galvanic separation between the primary circuit (power) and the secondary circuit (measurement). ATO series is an ideal current transformer for new smart grid applications.
