10.2 Technical data
Circuit breakers for fixed installation
10.2.1 Performance data and weights
( 1 ) At operating voltages lower than the rated voltage, the same values fundamentally apply as for the rated voltage. Higher values on request.
( 2 ) Individual unit without truck
( 3 ) Breakers for 4000 A with fan cooling
Rated voltage kV 12 17.5
Rated frequency Hz 50/60 50/60
Rated lightning impulse withstand voltage kV 75 95
Rated power frequency withstand voltage kV 28 38
