Why need SCB?
Traditionally SPD over current protection was provided by conventional circuit breakers or fuses, but this is not ideal for two reasons;
1. To pass the high frequency surge currents the fuses or circuit breakers need to have a higher AC current rating than consistent with good protection against overheating and fire within the SPD.
2. Surge currents can cause the fuses to blow or a circuit breaker to trip even when the SPD is still healthy, this is called nuisance tripping and it may not be detected, this leaves the facility with no surge protection until the trip is noticed.
