CT PCB Models and Versions 

 

The 

<

  

 

CT PCB series of current transducer has three different models that 

differ  for  primary  current  rating;  each  model  is  available  in  two  different  output 
versions  –  i.e. secondary current-output (standard) or secondary voltage-output (“V” 
version). 

 
The different models and versions of the CT PCB series are summarized in the 

following table (

Table 1
