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
