Earth Leakage Relay Electronic Motor Protection Relay with ZCT


KRIPAL Earth Leakage Relay is a micro-mrocessor based electronic protection device designed to recognize current leakage to ensure the protection of electrical installations and persons against direct and indirect contacts.

KRIPAL micro-processor based digital earth leakage relay used for monitoring low-level leakage or unbalanced current, due to insulation loss on conductors or faulty equipment installed in the network. It

incorporates a real time continuous display of the earth leakage current value in true RMS ampere and allows

the isolation of the faulty network or equipment if necessary.

A ring-type current transformer is used to detect and provide the continuous measurement of the leakage



Current measurement based on fundamental frequency, prevents nuisance tripping

Digital display or dial activated for ease of use

Robust casing protects the unit from external interference


Industrial equipment protection

Suitable for low voltage distribution protection



Sensitivity adjustment

30mA, 50mA, 75mA, 100mA, 125mA, 150mA, 200mA, 250mA, 300mA, 500mA,
