ABB ACB SACE Emax

The SACE New Emax family of air circuit-breakers consists of six sizes: X1, E1, E2, E3, E4, E6 up to 6300A.
All the SACE New Emax circuit-breakers have the same height and depth both in the fixed and withdrawable version and allow construction of compact switchgears.
Main benefits
Maximum safety is ensured in many different ways, such as racking-out with the door closed, degree of protection towards the outside up to IP54, various different safety locks and double insulation.
The innovative pole structure guarantees complete insulation between phases, and between the phases and neutral, while ensuring full possibility of inspection of the arcing chamber and the main contacts.
Lively performance. E1 now offers current ratings up to 1600A, whilst E3 is enhanced by the top performance level V.
Main features
Brilliant intelligence. The new generation of protection trip units is fitted with the latest advances in electronics, offering individual bespoke solutions for control and protection.
The new trip units, which are amazingly versatile and simply to use, offer important innovations, such as the brand-new intuitive operator interface allowing a complete control of the system with just a few simply key-strokes.
Furthermore, there are new protections, new alarms and connection to handheld and laptop PCs using Bluetooth technology.
With the new standardize system of accessories, studied and made for new Emax, work becomes easier, convenient, safe and rapid.

Thank you so much it was very helpful

[@ambassadorkees]

In=2000? That must be checked from the rating plug (#12 on the instruction photo), NOT from the specs sticker.
Though the frame is a 2000A, the trip unit can actually be downsized to 1600, 1250, 100, 800, 630(?)A by simply exchanging the rating plug.
And that will directly affect the reference In for all settings.

How to change the Rating plug ?

[@ambassadorkees]

@@amaan8670 pop out with a screwdriver (or 2, to go straight) and put a smaller one in.
Cannot be replaced with bigger than sold, only smaller.
However, L setting I1 can be as low as 40% of nominal current, so a lower rating plug is not that often needed.
Typically only with smaller currents in high short-circuit or high temperature conditions.

Thanks for your reply

Good just the InN was the protection for the neutral in percentage to the protection of the 3 phases
