SCB basic info
Surge Backup Protector is a special device designed and produced according to the requirements of Lec61643-4-43 in article 430.3 :" Before the circuit causes danger, appropriate overcurrent protection device should be used ". Also known as SPD Backup Protector, SCB or SSD.
Why Use SCB?
1, SCB can quickly cut off the access to prevent the lightning protection device fire, cut off the current is less than 3A when the deterioration of the lightning protection device, abnormal overvoltage of the distribution line causes the short circuit of the SPD conduction;
2. When lightning strikes occur, the SCB connected in series in front of SPD can ensure that the lightning does not tripped, damage, and lightning protection is continuous and effective;
3. The UP value (voltage protection level value) is very low when SCB passes through lightning current;
4, Rated short circuit breaking capacity up to 100KA;
SCB compared with duse and circuit breakers :
| SCB | Fuses and circuit breakers |
| SPD special backup protector, intelligent identification of lightning current and power frequency current. | Used for low voltage distribution leakage load, short circuit protection. |
| Surge impact is not tripped, residual low, lightning protection equipment continued effective | wrong action by surge, poor lightning protection performance, generally only 20KA, the equipment lost lightning protection and damage. |
| When the short circuit current >3A flowing through SPD is broken in 0.1-0.3s,SPD will not catch fire | Small current (several amperes) does not operate, its action value is 5~10 times its own rating,SPD fire combustion. |
| Power frequency short circuit breaking ability | Power frequency short circuit breaking capacity is insufficient, after the SPD fire, the short circuit arc continued to burn, causing a major fire accident. |
