The ABB 1SDA068169R1 is an XT2S 160 breaking part, 4-pole, rated Iu 160 A continuous. It is not a complete MCCB — it is the interrupter mechanism without a trip unit, functioning as a switch-disconnector or as the base for a field-installed trip block.
Rated voltage and frequency — what the 690 V and 50/60 Hz mean on the line
Rated voltage Ur 690 V AC covers standard 400/480 V systems with 50% headroom, and also suits 690 V mining, marine, or industrial installations where the line-to-line voltage is higher.
