SKIM600M Insulation Monitoring Device
SKIM600M is an insulation monitoring device for IT system main circuits and control circuits below AC690V and DC400V. SKIM600M can only perform insulation monitoring independently (the wiring method can only be used at the AC end) and cannot be combined with the insulation fault location.
