Hello Mads,


I‘d like to know if shipping to Luxembourg is as much as shipping to Germany. And are the „additional savings“ still available?  :)


Thank you!
Max

Shipping to Luxemborg is the same as to Germany, 52 Euro, for a XL package with GLS just under 20kg

I will take off 10% of the price for forum members :)

FWIW, that's almost pennies on the dollar.  Those things go new for kilobucks!

I'd jump on it (even with shipping to here), if only I needed one. :P

I know that, but if you don‘t really need it, it‘s still a lot of money with shipping. However, because it‘s an excellent offer and knowing that I‘ll use it one day for sure, I couldn‘t resist ;)

One question: are the capacities of the tabs all against the case?


Kind regards,
Max

I only checked from terminals to water inlet connections, as these are where the brackets connect to. Case is mentioned to be live, but I am not sure which side of the capacitor that is, or it is undetermined due to capacitive coupling?

Ill check this weekend.

Hmm, that style is usually case = common.  Is there continuity between water pipes and case?

I tried measuring on two different sizes of these that I have, both on unused units and refurbished.

There is no connection between case and water connections, the water connections are also sitting on ceramic insulators.

Good morning,


Thank you for measuring! I tried to find datasheet, which should mention what „case live“ means exactly, but apparently NWL doesn‘t produce this unit anymore.


Kind regards,
Max

I also tried to locate a datasheet and writing them did not give any results.

They are custom made units and I think that I just found a datasheet for a similar capacitor and trusted it to be very much identical to that.

I can not find a datasheet for NWL on my NAS, so it does not seem like I saved it.

I looked at the WFC series capacitors: http://www.nwl.com/products/capacitors/wfc-series/

And from their datasheet they can actually both be live or dead, depending on design: http://www.nwl.com/wp-content/uploads/pdf/nwl-wfc-series-capacitors-product-data.pdf

You found the same documents and conclusions as I did ;)

However I wouldn‘t call that document a datasheet... It‘s nothing more than a overview of the WFC series.


Thanks for looking anyway!
