Installation CSH1<strong>20</strong> and CSH<strong>20</strong>0<br />
Core balance CTs<br />
6/22<br />
Function<br />
The specifically designed CSH1<strong>20</strong> and CSH<strong>20</strong>0 core balance CTs are for direct<br />
residual current measurement. The only difference between them is the diameter.<br />
Due to their low voltage insulation, they can only be used on cables.<br />
Note: The CSH280 core balance CT available in the Motorpact offer is compatible with Sepam.<br />
