Product Parameter

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;
