Current Transducer CT 10-T  
IPN = 10 A  
For very accurate measurements of currents : DC, AC, pulsed...,  
with a galvanic isolation between the primary circuit (high power)  
and the secondary circuit (electronic circuit).

Notes : If the short-circuit has a duration more than 1 s, the primary current of  
the supply voltage must be interrupted for a short time to restore the  
transducer to proper working order. The internal protection is done by  
PTC resistors
