- Description
Order code 1SDA072961R1 is the ABB SACE Emax 2 E2.2B 1600 Ekip Dip LI 4p WMP, a four-pole 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. The part is the drawout truck alone; it needs a matching fixed part and cradle already installed to operate.

Selection Notes
The fourth pole carries 100% of Iu, so this moving part is for a four-wire 1600 A circuit where the neutral must switch with the phases — the three-pole 1600 A WMP in the same E2.2B frame leaves the neutral through-connected. Performance class B holds the 42 kA Icw flat at both 1 s and 3 s, but Ekip Dip LI has no short-time delay (S) stage, so it still trips instantaneously on a fault; specify the LSI-equipped 1600 A four-pole truck instead where selective coordination with downstream breakers is required.
