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 ELPR is earth leakage relay ( ELR ), a protection device to be used in electrical installations against electric shock and / or damage to equipment caused by punctured or weak insulations or contact to live parts. Instrument operates by monitoring the earth leakage current through CBCT and disconnecting the circuit in case of hazardous levels of earth leakage currents.
RISH ELPR is available in two versions, Smart and Smart+

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 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.
