Insulation monitoring relays for unearthed supply systems
Ordering details

Description 2

2CDC 251 017 V0012 The high reliability of an IT system is guaranteed thanks to continuous insulation monitoring.
An insulation monitoring device recognizes insulation faults as they develop, and immediately
reports that the value has fallen below the minimum. This prevents operational interruption
caused by a second, more severe insulation fault.
ABB developed a totally new range of insulation monitors for AC, DC or mixed AC/DC IT Sys-
tems up to 690 V AC or 1000 V DC. With only 4 devices most standard applications can be
served. Additionally a version for solar applications with increased earth leakage capacitance
has been added.
