King Alfred - placed but not working (5)

I believe the answer is:

kaput

I'm a little stuck... Click here to teach me more about this clue!

'not working' is the definition.
(kaput can mean broken)

'king alfred placed' is the wordplay.
'king alfred' becomes 'ka' (this might be a standard abbreviation which I don't know about).
'placed' becomes 'put' (I've seen this before).
'ka'+'put'='KAPUT'

'but' acts as a link.

Can you help me to learn more?

(Other definitions for kaput that I've seen before include "Broken (sl.)" , "out of action" , "Defunct (informal)" , "Bust" , "Wiped out" .)

I've seen this clue in the Sydney Morning Herald.
