If a compressor starts then trips electrically then invariably it is High current. Compare the current taken with the manufacturers data sheet

Hermetic Compressors:

 

Start Capacitor High current

Run Capacitor Stall

Semi & Open check all protective devices

A good ap to help is Embraco for Iphone or andriod

Yasir,

There are a number of issues why a compressor trips after a few minutes, and they vary depending on the compressor and system type.

If the compressor that is tripping shortly after starting is also suffering with a high pressure issue you could be tripping on the high pressure switch. An auto reset high pressure switch will have a set pressure differential, which will require the discharge pressure to drop a set value below the cut out setting, normally 3.0 to 4.0Bar for Danfoss KP range. Other manufactures may differ. 

What type of compressor is it? Semi-hermetic, Hermetic or open drive? What type of system is it? Flooded or DX?
