In the 'Gallery' section at the bottom of the page is a chart showing the shield ratings for each ship with each of the shield generators it can equip.

Hope that helps.

Well you are dropping the class form 4 to 3 so it is not sized correctly for your hull/mass. Look at the numbers.

You should look for a class 4 shield.

 

[TheNameIsJambo]

Bumping this up as I'm interested too :-D

Class 4 > Class 3. The optimal hull mass is way too low, look at your 'Current Mass'. It's 80T more than optimal.

I have an A-Grade, Class 4 shield generator on my Cobra. I can destroy Asps, T6s, etc. by ramming them, without losing my shield at all. Then again, my Cobra is worth 8.5 million credits.

Think of Class as size and Rating as quality.
Don't put a Class 3 in a Class 4 slot.

 

[Hamerstein]

The size of the shield generator is your first indicator, the one you have is a class 4, fitted into a class 4 module slot. The new one is a class 3, it's designed for a smaller ship than the Cobra. The A to E refers to rating, which is how good it is compared to the rest of it's class size.

Optimal Hull mass indicated the point where the shield starts to lose effectiveness - as you're asking it to protect more mass than is ideal. Maximum hull mass is the point where it can no longer protect the ship - you won't be allowed to install a shield that can't protect you at all.

So with the 3A, you're already exceeding the optimal hull mass by ~80 tonne, as we don't know the rate of degradation for exceeding optimal mass, it's hard to work out if this would be better than a 4E - a lower rated shield, but running optimally as it's optimal mass exceeds the mass of your Cobra.

I'd tread carefully, it may be a bit better, but to be safe, go for a better rated class 4 shield.

Theres a chart describing them on the elite-dangerous wikia com website

You are putting a smaller shield generator in. Class 3 is smaller than class 4 (Cobra has class 4 module slot for shield gen's). With that mentioned, the shield gen you have there is better yes (hang on though, keep reading). In that its tougher to knock down thanks to its integrity and rating. However, since its smaller than your module space can hold it also has less optimal hull mass/max hull mass, meaning it has a smaller area covered/not power enough to shield your whole ship properly. Your max mass is 420T as you can see to the right in the ship info (your image), and the shield gen you want to buy has 413T max mass.

I would get the next class 4 shield if i was you.

Class 4 > Class 3.

True, in general.

The optimal hull mass is way too low, look at your 'Current Mass'. It's 80T more than optimal.

It's important to realise that Shield Generators use your ship's Hull Mass, which is fixed for each ship and doesn't vary with outfitting or cargo (the Cobra, for example, has a Hull Mass of 180).

My pleasure.

If it helps, here's a summary I wrote of how shield ratings are calculated:

sorry to sound a bit New but how can a shield generator help with ramming ships is it the mass size that counts?

Shields absorb ramming damage, so the stronger your shield the bigger the impact it will protect you against.

Great summary, thank you (I'd rep you but apparently I have to spread the love before I can again - have a cookie instead )

Thank you Space Mates, you are so precious!!!!!
So..... I'll reinstall my default shield, save money, and I'll buy a class 4 'couse..... 4 is better than 3! Cobra needs 4!!!!!!! Thanks! ;-)

This thing is very interesting!!! My Cobra now worth 900k more or less and I'd like to keep my Cobra forever! So, little by little, I'll keep on upgrading!!!

there might be a power issue that's the only thing that is holding me back from upgrading at moment saying that I am running 2 beams might have to figure a work around

 

[clivewil]

anyone know offhand where i might find a 4A shield gen in Empire space? no luck finding one so far, not even on Achenar but i didn't search every station

I need to refit a Class 4 shield too!!!! I've made the mistake.... Now I'm in 42 Aquilae, can't find it.... Do you know A System nearby with Class 4??? Thanks!

EDIT: Found it!!! In YAKABUGAI, Levi-Montalcini City (tribute to the great Italian scientist....!!! ) 174000 cr

More than one shield generator

Is it possible to have more than one shield generator in a single ship? Will you get 6 rings of protection?
Guessing if it is possible you would need a top notch power plant.

Thanks for any help.

dont think so tim
