Earth Leakage Relay Electronic Motor Protection Relay with ZCT

Description:

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.

Benefit:

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

Applications:

Industrial equipment protection

Suitable for low voltage distribution protection
