Can IM20-H show fault current?

[Stuart_Cheng]

Hi All,

As the title, can IM20-H show fault current instead of resistance? Thank you.

Hello Stuart, 

IM20-H is IEC offer, the network insulation will be monitored in the form of resistance

(Ω) . Not supported in form of current measurement. The NEMA offers supports the leakage current.
