- Description
A three-pole Tmax XT7S M unit rated 1600 A, the ABB 1SDA101389R1 pairs a stored-energy plus lever operating mechanism with an Ekip Touch Measuring LSI electronic release. It carries a 50 kA breaking capacity at 400-440 V AC, a 20 kA short-time withstand (Icw), and a 690 V AC rated voltage.

Selection Notes
At 1600 A this is the top of the XT7S M three-pole range covered here - use it as a main or tie breaker ahead of the 800, 1000, and 1250 A siblings rather than on a feeder sized well below 1600 A. The Ekip Touch Measuring LSI release's S (short-time) stage, paired with the 20 kA/1 s Icw, supports selective coordination with downstream devices on main-incomer duty.
