This is a solenoid from an Italian made marine windlass.
Could you please help me understand the specifications written on it?
From what I know, the coil and connector is 12V because that is the voltage on the connections.
It was hooked up to an Optima Red Top battery for operations.
Here is some technical data for a product that looks very similar in markings, save for the manufacturer or supplier logo which is a very Italian "Ravioli" rather than "Quick".
They claim it has a feature for quick drop-out and slow pull in for reversing applications. Also the coil appears to be intermittent duty only (80% duty cycle maximum) as marked on your unit- coil dissipation is a hefty 20W. Maximum on-time 15 minutes.
Your "Bobina" (coil) is 12V.
150A is the maximum continuous current (limited by heating) and it can break 720A.
"Class 300 - 50%" appears to mean maximum 300 operations per hour at 50% of rated current (not sure whether it's 50% of the 150A or the higher 180A intermittent rating).
As with all ratings, it's best to stay well away from the maximums if you want long and reliable life span. No indication is given (that I can see) of the expected life in the webpage or pdf document that are linked. The 'mechanical life' of 2,000,000 operations is with zero load and is basically how long it takes to shake itself to death. Electrical life will likely be much, much fewer operations (could be as low as thousands or as high as 50,000 or 100,000) and very much dependent on load current and nature of the load.
