5.1.2.2 Circuit breaker (input current > 800 A)
At currents greater than 800 A, the circuit breaker, which is located in the center of the
cabinet, takes on the function of isolating the system from the supply and the overload and
short-circuit protection. The circuit breaker is internally activated and has its own internal
power supply.
The tripping current on the line-side must be set according to the conditions of the system.
The tripping current is set as follows in the default factory setting:
