Rated current and frame size — what In=100A and Iu=160A mean for your panel
The 1SDA068145R1 carries a rated current In of 100 A on a 160 A frame (Iu). The Iu is the thermal-magnetic frame size of the XT4N breaker; the In is the installed trip unit rating. This means the breaker body and bus bars are sized for 160 A continuous, but the Ekip LS/I trip unit is set to protect at 100 A — a common configuration when you want a larger frame for short-circuit withstand or future upsizing without swapping the entire breaker. Four poles cover three phases plus neutral, standard for 4-wire distribution systems. The 690 V rated voltage at 50/60 Hz handles 400 V, 480 V, and 690 V line-to-line panels — common in European and North American industrial installations.
Trip unit: Ekip LS/I — what it protects and how it adjusts
The Ekip LS/I is an electronic trip unit with LS (long-time and short-time) protection plus I (instantaneous) protection. Long-time delay handles overloads; short-time delay allows selectivity with downstream breakers; instantaneous clears high faults fast. The trip curves are adjustable via dip switches or a front potentiometer — no software required. The 'F F' suffix in the type code indicates fixed thermal and fixed magnetic settings — the trip thresholds are factory-set and not field-adjustable on this variant. If you need adjustable protection, look for the 'A' (adjustable) suffix in the XT4 family.
Lifecycle and sourcing — active production, quoted to order
Sourced through independent distribution channels; availability and current pricing confirmed at RFQ. Estimated lead time is 2–4 weeks for production quantities — typical for a catalog item not held in high-volume stock.
