1SDA068104R1 — XT4N 250 TMA 200 A, 4-Pole
That's the ABB XT4N 250 TMA 200-2000 4p F F InN=50% — a distribution circuit breaker with a fixed continuous current rating of 200 A (In) on a 250 A frame (Iu). Four poles, rated to 690 V AC, 50/60 Hz. The TMA trip unit is thermal-magnetic, adjustable? The type suffix InN=50% means the continuous current setting is pegged at 50% of the trip unit's nominal range — so no field adjustment up; it's fixed at that point. This is a current-production part, quoted to order with a 2-4 week lead.
