Insulation monitor
MH 5880

The insulation monitors MK 5880N and MH 5880 of the VARIMETER IMD family provides best insulation monitoring of pure three-phase and AC IT systems in a state of the art way fulfilling the relevant standards. The adjustment of the setting values is simple and user friendly done on 2 rotary switches on the front of the device. The MH 5880 also has a galvanic separated analogue output and a 11 step LED chain for display the actual insulation value.
