The 1SDA068142R1 is an ABB XT4N 160 Ekip LS/I molded case circuit breaker rated for 40 A continuous (In) on a 160 A frame, 4 poles, 690 V AC, 50/60 Hz. The Ekip LS/I electronic trip unit handles long-time and instantaneous protection, so it fits feeder or main breaker roles in distribution panels. The 160 A frame (Iu) gives you headroom: the breaker's thermal and mechanical capacity supports uprating later by swapping the trip unit without replacing the entire breaker.
Lifecycle & Sourcing
Estimated lead time runs 2 to 4 weeks, so it quotes to order without extended backlog for this active line.
Mounting & Layout
Four-pole version shares the same footprint as the three-pole variant, so panel layouts stay consistent between 3P and 4P designs.
