Testermeter- SKIM400 Insulation Monitoring Device below AC400V
| SKIM400 is an insulation monitoring device for IT system main circuits and control circuits below AC, DC and AC/DC 400V. SKIM400 can only perform insulation monitoring independently and cannot be combined with the insulation fault location. |
