RISH Relay - VR monitors AC voltage of a system/equipment and protects it from overvoltage, undervoltage and phase failure issues. As well as it indicates the occurrence of faults with help of LED indications.

• Compact size : Width of 17.5 mm
• True RMS measurement
• Under voltage, Over voltage protectionas well as protection against Phase unbalance, Phase failure, Incorrect phase sequence & Neutral failure
• LED indication for faults
• Disabling of Over & Under Voltage fault on site is possible
• Onsite selection of VLL / VLN value based tripping
• Self powered
• Adjustable Nominal voltage, Trip point, Trip time delay
• Compliance to International Safety standard IEC 61010-1-2010
