Rish ELPR - Earth Leakage Protection Relay

The purpose of Earth Leakage protection is to measure the Earth leakage current of an electrical installation, or part of an installation, and interrupt the power supply if the Earth-Leakage current becomes dangerous to property.

Rish Relay - PHR

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

Rish Relay - VR

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

Rish Relay - AR

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

Rish ELR - Digital Earth Leakage Relay (96 x 96 mm & DIN Rail)

Rish Relay 252-PAx - AC Current Relay

The AC Current provides continuous surveillance of the monitored circuit. When the measured current moves outside the set point limit, the relay will operate. An adjustable time delay is provided to prevent the relay from tripping for a predetermined period to prevent nuisance tripping.

Rish Relay - V/Hz (Digital Line Monitoring Relay)

Rish Relay V/Hz is used to protect against Over Voltage, Under Voltage, Phase Unbalance, Phase Sequence detection, Phase Failure detection, Under and Over Frequency conditions.

Rish Relay 253-PVx - AC Voltage Relay with Adjustable Differential

The AC Voltage Protectors provide continuous surveillance of the monitored circuit. When the measured voltage moves outside the set point limit, the relay will operate, giving an alarm and or initiation signal.
