Contact voltage limiting value   

 

25 V or 50 V

The contact voltage is calculated relating to I

∆N

 (standard) or 2 

× I

∆N

 (selective).

For the contact voltage, the fault loop resistance is calculated as follows:

∆

The entire measuring range complies with the requirements specified in EN61557-6. The specified
accuracies apply to the entire operating range.
