Insulation monitoring devices meeting all the requirements for the supervision of the medical IT power supply system (MIS). It evaluates the insulation resistance in the range of 5 kOhm to 10 MOhm. The thermal load of the transformer can be sensed by three sensor types, PT100, NTC or an opening contact. The current load is monitored by current measuring transformers of the HIG-MT series.

Lightning impulse current and surge arresters type T1+T2+T3. They are suitable for objects with considerable levels of protection LPL I and LPL II and installed as close as possible to the point where overhead line enters the building, i.e. in the main distribution boards.

Lightning impulse current and surge arresters type T1+T2 intended for photovoltaic systems (PV) at Y connection. They are suitable for level LPL I or II and installed on the DC side in PV applications with external LPS, where a sufficient distance "s" is not observed.
