110V / 240V Over Voltage Digital Protection Relay 30mA 50mA 75mA 100mA

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.

Specifications:

Functions:

1. 25 selectable sensitivity settings 30mA to 30A

2. 9 selectable time delays: 0-3s

3. earth leakage level indicators

4. detection of no connection of ZCT

5. relay tripped indicator

6. trip starting indicator

7. protected againest nuisance tripping

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
