Product Detail
The short circuit & earth fault indicator is used for detecting the short circuit and earth fault of the electrical equipment

Function:

1. Short circuit alarming; 

2. Earthing alarming; 

3. Auto reset ; 

4. Test / Reset ;

5. Alarming information remote transmission

6. Low voltage of the battery alarming indication:

Technical data: 

1. Short circuit alarming  current:  150A to 2000A

2. Earthing alarming current:     10A ,20 A,30A,40A,50A,60A+-10% delay 120ms 

3: Temperature range :            -15 to +60

4. Humidty:                      <=95%

5.Earth lead length :              3.5m

6.Conduct  optical fiber length     10m(MAX)

7.Power supply:                  lithium battery 3.6V/2.45Ah

8. Auto-reset time :               7s,1hrs,2hrs,4hrs  9. Output relay :     120 V AC 1A, 30V DC 2A

10.Cutting hole dimension:        91*44mm 11.Main controller dimension :     95*50*80mm

12.Cutting hole size :             91*44 mm  13.Protection class : Main Controller :IP40  Sensor:IP65

Characteristic 

1. With high reliability MCU, lower power consumption while monitoring;

2. Passive sensor to be used;

3. With long life of lithium battery for power supply ,has low voltage detect function 

4. Three phases independence testing

5. Use optical fiber to transimit the short circuit  signal and separate the sensor circuit from high voltage, so ensure the safety and reliability.

6.  With self-locking type output relay
