It mates with the corresponding XT4 base and arc chamber to form a complete MCCB. ## Rated current and breaking capacity — what the numbers mean for fit Iu 250 A is the continuous current rating at 40 °C ambient — the breaking part carries this current indefinitely without exceeding the temperature rise limits of the XT4 frame. For derating above 40 °C, apply the ABB XT4 derating curve from the application guide. Icu 36 kA at 415 V AC is the ultimate short-circuit breaking capacity — the unit can interrupt a fault current up to 36 kA once and remain functional after the event, per IEC 60947-2. At 690 V rated voltage, the breaking capacity is lower; check the coordination tables for the specific system voltage. ## Lifecycle and sourcing — active production, quoted per BOM Sourced to order against the BOM quantity from authorized distribution. Lead time is estimated at 2–4 weeks; volume pricing and firm availability confirmed at RFQ.","metaTitle":"ABB 1SDA068178R1 XT4N 250 MCCB Breaking Part, 4P, Iu 250 A","metaDescription":"ABB 1SDA068178R1 XT4N 250 molded case circuit breaker breaking part, 4-pole, Iu 250 A, Icu 36 kA at 415 V, 690 V rated.
