- Description
Built as a four-pole fixed-mount breaker with rear horizontal terminals, the ABB 1SDA071602R1 is a SACE Emax 2 E2.2H 1250 Ekip Dip LSI air circuit breaker rated 1250 A. It reaches a 100 kA breaking capacity (Icu) at 400 V AC and an 85 kA short-time withstand (Icw) for 1 s, with the LSI release enabling selective tripping ahead of downstream protection.

Selection Notes
The fourth pole on this fixed, rear-horizontal breaker switches the neutral, distinguishing it from the three-pole version for four-wire 690 V AC installations. The LSI release's short-time delay stage supports selective coordination with downstream breakers ahead of the instantaneous trip. At 1250 A, Icu reaches 100 kA at 400 V AC with an 85 kA Icw for 1 s.
