Selection Notes
The adjustable short-time stage lets this breaker stay closed through a downstream fault on a timed delay, supporting a main-incomer role at 3200 A ahead of smaller selectively coordinated breakers - the LI-only 1SDA072511R1 in the same WMP, H-level frame trips instantaneously instead. Icu of 100 kA and Icw of 85 kA/1 s are the highest ratings available in the Emax 2 range at 400 V AC. As a WMP unit it requires a matching E4.2 fixed part already installed in the switchboard before it can be racked in.
