Protector Relays

RISH Relay -PHR monitors AC voltage of a system/equipment and protects it from phase failure issues. Suits applications such as  Control close loop operations, Conveyor system, motor protection from faults like incorrect phase sequence, unbalance in phase or loss of phase.

• True RMS measurement
• Self Powered
• Instrument automatically clears (resets) itself as soon asfault condition is recovered
• Compliance to International Safety standard IEC 61010-1-2010
• LED indication for Unbalance, Phase Fail condition and incorrect Phase Sequence condition
• Well suited for 3PH 3W and 3PH 4W applications

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

RISH Relay - AR monitors AC current of a system/equipment and protects it from overcurrent, undercurrent and current unbalance. As well as it indicates the occurrence of faults with help of LED indications. It is a potentiometer based relay thus it is easy to programme trip points and time delays.

• Over Current, Under Current& Current Unbalance Protection
• Nominal current can be set from 1A - 5A on-site
• Adjustable trip point and time delay for Under current and Over current
• Compliance to International Safety standard IEC 61010-1- 2010
• TRMS measurement
• LED indication for Power on, & faults like Under current, Over current, Current unbalance
