- Description
Rear-horizontal-terminal and four-pole, the ABB 1SDA071792R1 is a fixed SACE Emax 2 E4.2H Ekip Dip LSI air circuit breaker rated 3200 A with 100 kA ultimate breaking capacity at 400 V AC. The LSI release adds an adjustable short-time delay to the overload and instantaneous functions at ABB's largest Emax 2 frame size.

Selection Notes
The fourth pole switches and protects the neutral at the full 3200 A rating, for installations that need a breaking neutral at the top of the Emax 2 current range. With the LSI short-time delay, this breaker can hold through a downstream fault on a timed setting, supporting a main-incomer role - the LI-only 1SDA071791R1 in the same F HR body trips instantaneously instead. Its fixed, rear-horizontal-terminal construction runs a 425 W power loss, well under the equivalent WMP unit's 743 W.
