- Description
Order code 1SDA072782R1 is the ABB SACE Emax 2 E1.2N 1000 Ekip Dip LSI 4p WMP, a four-pole withdrawable moving part rated 1000 A (Iu) with a 66 kA ultimate breaking capacity (Icu) at 400 V AC. It supplies the drawout truck only — a compatible fixed part and cradle must already be in place for the breaker to operate.

Selection Notes
The short-time delay (S) stage in Ekip Dip LSI, combined with a 50 kA/1 s Icw, is what makes this 1000 A moving part suitable for a main incomer position with selective coordination downstream, unlike the LI-only moving parts in the same E1.2N frame that trip instantaneously. Choosing the withdrawable WMP version over the fixed F F equivalent trades a bolted connection for drawout isolation, letting the truck be racked out for maintenance without disconnecting the busbar.
