The 1SDA068136R1: Three-pole MCCB in XT4 frame, rated 250 A continuous at 690 V, 50/60 Hz. Ships with Ekip LSI electronic trip unit.
250 A In sets overload threshold; Ekip LSI trip unit allows short-time delay adjustment for selective coordination.
Within the XT4 frame, the 1SDA068135R1 (XT4N 250 with Ekip G trip unit) is the closest functional sibling — same frame, same current rating, but with a ground-fault protection module instead of LSI. No pin-compatible second source exists outside ABB.
Both In and Iu are 250 A — the breaker is rated for continuous 250 A load without derating.
Alternative models and sibling configurations in the same ABB series. For obsolete or discontinued parts, these models can serve as compatible replacements or functional alternatives for plant maintenance.
