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). 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.
The rated continuous current In is 200 A; the frame rating Iu is 250 A.
Physically yes — same frame XT4, same dimensions, same footprint and mounting. Electrically the In differs (200 A vs 225 A), so the overcurrent protection setting changes. If the panel design accommodates a 200 A trip, it will fit without rewiring; verify coordination with the existing loads.
