AC Current transducer APR-B420L  
IPN = 10 .. 400 A  
Split core transducer for the electronic measurement distorted AC  
waveforms current, with galvanic isolation between the primary circuit  
(power) and the secondary circuit (measurement). Switch selectable  
ranges and True RMS 4-20mA current output.
