For further details on the cell type assignments see the section on dimensions for circuit-breaker on withdrawable assembly
1)
At operating voltages lower than the rated voltage, the same values fundamentally apply as for the rated voltage. Higher values on request.
2)
With a motorized withdrawable part, the weight is increased by approx. 2 kg.
