- Description
ABB's 1SDA073012R1 covers the four-pole point in the SACE Emax 2 E2.2N 2000 Ekip Dip LSI line: 2000 A rated current, four poles with a 100%-rated neutral, and 66 kA breaking capacity at 400 V AC. The LSI release pairs long-time overload and instantaneous protection with an adjustable short-time delay for coordinated tripping.

Selection Notes
The fourth pole carries the same 100% rated current as the phases, so this version suits a solidly-grounded or TT distribution board where the neutral must be switched and protected to the same 2000 A rating as the phases. Against the three-pole 1SDA072382R1 in the same N/LSI combination, pick this 4P unit when the installation needs a switched and breaking neutral rather than a fixed or unprotected one. It remains a WMP unit, so a matching E2.2 fixed part has to be installed in the cubicle first.
