Compressor capacitor

[N2ae86]

Gents,

Wonder if anyone can help with a bit of advice.

I was given a compressor a short while ago that doesn't want to start. Plan is to fix it up and give it to my dad to use. Having worked on it I suspect the issue is the capacitor (only thing left it can be).

The dead capacitor markings are

30UF ± 5%
450v
400V

--------

400v ~ Mk
450v ~120/50
500v ~ 120/10

25/70 0c 50HZ


I dont actually have a clue what any of that means but google tells me I need a 450V 30UF capacitor.

Before I buy one - do I need to match the other information on the markings or will any 450V 30UF capacitor do the job?

Thanks in advance.

James

Recently bought one for my lathe motor from Ebay. Not very expensive & easy to fit, remembering to disconnect from the mains before doing so, of course.
The first set of markings are the capacitor value (30 uF) +- 5% tolerance on capacitor value(450V) max working voltage. You can forget about the other numbers

Thanks RonA - thats exactly what I needed to know!

I bought one from a local electronics and general electrics shop for a pressure washer. It was physically smaller but same capacity and worked fine. It cost just under £8.
