The insulation monitoring relays of the CM-IWx range guarantee a continuous insulation monitoring of an IT system. The devices recognize insulation faults as they develop and trip immediately if the value has fallen below the minimum set threshold (1-200 kOhm). This ensures a reliable operation of the system and prevents operational interruption caused by a second, more severe, insulation fault which may lead to a short circuit tripping the main circuit breaker.
Main benefits
Down-time reduction
Safe and reliable operation
Easy to install
Main features
Monitoring of system voltages up 1000 V DC and 690 V AC
Monitoring of system leakage capacitances up to 2000 µF
All kind of systems can be monitored: 2-wire, 3-wire, 4-wire as well as battery systems
Prognostic measuring principle
Interrupted wire detection configurable
Non-volatile fault storage configurable
