5000A power switch - proper anti-arcing capacitor

I have a 5000A in the shop that has had the power switch replaced (not by me) with no safety capacitor to prevent arcing. This seems to me like it would be a safety hazard.

My typical work is on turntables and I'm frequently replacing dead safety caps for motor switches, usually on Duals. The film caps I have on hand are Phillips .068uf/250v polyesters (like these), Panasonic .068uf/275v X2 (like these) and WIMA .01uf/275v X2.

Would these work? Is there one that would be best?
 
I don't know what the stock value is - guessing 0.047µF ? - based on the fact that having a capacitor fitted is better than no capacitor I would use the 0.068µF @275V. Having no anti-arcing capacitor isn't a safety issue, but it will mess up that replacement switch much faster without one. :)

Update:
I checked for the correct value and it's 0.022µF @600VDC, so if you have 2 of those Wima type capacitors, two of them in parallel will do the trick. ;)
