- Description
1SDA072331R1 is the ABB SACE Emax 2 E2.2B 1600 Ekip Dip LI 3p WMP, a withdrawable moving part on the larger E2.2 frame, rated 1600 A (Iu) with a 42 kA ultimate breaking capacity (Icu) at 400 V AC. It is the drawout truck only and needs an already-fitted fixed part and cradle to operate.

Selection Notes
The E2.2 frame carries this unit to 1600 A, above anything the E1.2 frame in this range reaches, while its performance class B holds the 42 kA Icw flat across both the 1 s and 3 s withstand ratings — a steadier short-time withstand than the E1.2N moving parts, whose 3 s figure drops below the 1 s value. Ekip Dip LI has no short-time delay (S) stage, so it trips instantaneously on a fault; for a 1600 A position needing selective coordination with downstream breakers, the LSI-equipped version of this frame and current rating is the one to specify instead.
