- Description
Four-pole and rated 1600 A, the ABB 1SDA071612R1 is a SACE Emax 2 E2.2B Ekip Dip LSI air circuit breaker in fixed form with rear horizontal terminals. Breaking capacity (Icu) reaches 42 kA at 400 V AC, with a matching 42 kA short-time withstand (Icw) for both 1 s and 3 s. The fourth pole switches the neutral for four-wire 690 V AC distribution.

Selection Notes
The fourth pole on this version switches the neutral conductor, making it the choice over the three-pole fixed version for four-wire 690 V AC distribution where the neutral needs isolation along with the phases. Icu holds at 42 kA with a 42 kA Icw sustained for 3 s, and the LSI release's short-time delay stage supports selective coordination with downstream devices. Fixed, rear-horizontal terminals mean no separate cradle is needed for this 1600 A unit.
