The ABB 1SDA068133R1 is a 3-pole XT4N 160 molded case circuit breaker with an Ekip LSI trip unit set to 63 A, on a 160 A frame. Rated voltage is 690 VAC at 50/60 Hz. The 63 A rating is what protects your downstream conductors; the 160 A frame handles the mechanical and thermal margin — order the correct In. Trip curve covers long-time, short-time, and instantaneous protection — mate it with an upstream breaker for full selectivity. No add-on modules needed for LSI; it's built into the Ekip unit.
What this breaker doesn't do
No ground-fault protection in the standard LSI; if you need G, order the Ekip LSI/G variant. Also this is a 3-pole device — 4-pole versions share the XT4 frame but carry a different order code.
