Breaking part for the XT2N 160 — what it replaces
The 1SDA068168R1: This is the 4-pole breaking part (interchangeable trip unit + contacts) for the ABB XT2N 160 MCCB frame. The 'breaking part' designation means it is the serviceable internal assembly; the line-side terminals and arc chamber are integrated, but the external rotary handle or motor operator mounts separately on the XT2 frame. Only the breaking part is swapped during a trip-unit upgrade or after a fault-clearing event.
