ABB CM-IVN.P 1SVR760669R9400 Monitoring relay

The high reliability of IT systems is ensured by continuous insulation monitoring. Insulation monitoring detects developing insulation faults and immediately reports that the value has fallen below the minimum. This prevents business interruption due to a second, more severe insulation fault. ABB developed a completely new insulation monitoring device series for AC, DC or AC/DC IT systems up to 690 V AC or 1000 V DC. With only 4 devices, most standard applications can be operated. In addition, a version for solar applications with increased leakage capacity has been added.
