design of the Multi-9 range provides current limitation with far better protection than con-ventional circuit breakers. For example, on a 6A rating with a prospective short circuit of 5000A, the current will be limited at 350A or 7%. Installation of current limiting circuit breakers offers several advantages: # Better network protection
