ABB 1SDA068135R1 is a current-production XT4N distribution breaker rated 160 A continuous (In and Iu both 160 A) with Ekip LSI electronic trip. Three poles, 690 VAC, 50/60 Hz — covers standard 3-phase distribution panels. The Ekip LSI unit provides adjustable long-time, short-time, and instantaneous protection. That's the key differentiator from the thermal-magnetic peers in the same frame.
