Vigirex™ ground-fault relays, with associated sensors (current transformers), measure the leakage current in an electrical installation to detect levels that may be damaging. When used for protection, they cause an associated circuit breaker or switch to interrupt the supply of power to the protected system. They may also be used for monitoring only, with output to an alarm.

Vigirex relays can be used at all levels of an installation: power distribution, industrial control and final distribution, as well as with a variety of OEM equipment. There is a wide range of Vigirex models, mounting options and sensors to best suit your application.
