Selection Notes
The adjustable short-time stage lets this breaker hold through a downstream fault on a timed delay, supporting a main-incomer role ahead of smaller selectively coordinated breakers - the LI-only equivalent in the 2000 A step trips instantaneously instead. At 2500 A it is the higher-current, same-frame step above the 2000 A E2.2S WMP units, letting the physical E2.2 envelope cover a wider current range before moving up to E4.2. As a WMP unit it requires a matching E2.2 fixed part already mounted in the switchboard.
