Circuit isolation Miniature Circuit Breaker

 

 

 

 

Detailed Specifiction

 

1. Usage: SPGM-63P DC circuit-breaker is used for solar energy PV generation with rated           

 operating voltage up to DC 1000V which adopts special arc extinction and current limitation system to break fault current in DC distribution system rapidly.

 

2. working principle 

The circuit-breaker could protect the important element in solar PV generation system- PV modules from the damage of DC reverse current and AC feedback current

 because of inverter fault. So that solar energy PV generation system can operate reliably.

 1).  Quick closing and opening mechanism.

 2).  Inm: 63A(1~63A);  Icn: 6KA/DC 100V

 3)   Icn: 6kA/DC 1000V

 4)   Instruction window

 5). No edge joint in the obverse side

 6).  Isolating function

 

 

4 Standard

1) SP5-63 Pseries solar energy generation miniature DC
    circuit-breakers comply with the following standard:

2) IEC 60947-2 GB 10148.2:

3) Circuit-breakers for overcurrent protection for household
    and similar installation-Part 2: Circuit-breakers for a.c. and d.c.
   operation

 

5 Application environment:

 

1. The altitude should not exceed 2000m. If it is higher than 2000m, the capacity should be derated. For details, see derating
    capacity table.
2. The ambient air temperature is between -25°C and +40°C, its average over a periods of 24h is +35°C. When ambient air
    temperature is higher than +40°C or lower than -25°C, please contact manufacture.
3. Resistance to moisture (three proofings);
4. Resistance to salt spray and oil mist (three proofings);
5. Resistance to fungus (three proofings);
6. The produce should be installed in Distribution Box with waterproof measure
