Vigirex™ Ground-fault Relays
Improved protection and reduced downtime for process machines

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. They are designed for AC installations implementing a variety of solidly-grounded arrangements and are suitable to monitor voltages up to 600 Vac and frequencies ranging from 50/60 Hz and 400 Hz.

There is a wide range of Vigirex models, mounting options and sensors to best suit your application.

• Panel or DIN-mount installation
• Variety of sensors for a wide range of amperages
• Models for most common power supply voltages
• Ground-fault settings from 30 mA to 30 Amps
• Response from instantaneous (no intentional delay) to 4.5 seconds
• Outputs that may be used for protection or alarming
