- Description
Order code 1SDA072391R1 identifies the three-pole moving part of a SACE Emax 2 E2.2S 2000 Ekip Dip LI air circuit breaker: 2000 A rated current and 85 kA ultimate breaking capacity at 400 V AC. The LI release covers long-time overload and instantaneous short-circuit protection without an adjustable short-time stage.

Selection Notes
The S performance level pushes Icu to 85 kA at 400 V AC, 19 kA above the E2.2N units in the same frame, which matters on boards with a higher prospective short-circuit current than the N-level breakers cover. With an LI release instead of LSI, this breaker trips instantaneously on a short circuit rather than holding a timed short-time delay - choose the LSI-equipped sibling instead where the incomer must stay closed through a downstream fault for selective coordination. As a WMP unit it ships without a fixed part, so a compatible E2.2 cradle must already be installed.
