What this breaking part is and isn't
The 1SDA068171R1 is the switching mechanism only — the 'breaking part' of an ABB XT2L 160 MCCB. It mates with a separate base and trip unit to form a complete molded case circuit breaker. If you're ordering this for a panel build, confirm you already have the matching base; this part alone won't mount to the bus. Rated Iu 160 A continuous current on the XT2 frame, with a fault-breaking capacity Icu of 120 kA at 415 V AC. That's enough clearing capacity for most industrial main feeders and large subfeeders — the 120 kA rating means it can safely interrupt a bolted fault up to that level without venting or cascading upstream.
Panel fit and electrical specs
Four-pole configuration handles three-phase plus neutral switching — common for TN-S or TN-C-S systems where the neutral needs isolation. Rated voltage 690 V AC gives headroom above the standard 400/480 V distribution levels. Frequency rated 50/60 Hz, so it's universal for global installations without derating.
Sourcing and lifecycle
Sourced and quoted to order against your BOM quantity. No minimum order quantity beyond what the supplier requires for this ABB line.
