Default Compressor causing breaker to trip at high pressure.

I picked up a 10 hp compressor, dual heads, 2 stage, 120 gallon tank.
The Pump has a centrifical unloader. The Motor is 3 phase 240 of which
I run on my 10hp rotary phase converter wired with 8-3 With Ground and
a 40 amp breaker.
The compressor starts fine but the breaker trips when the compressor is
near its top end around 160 psi. What are some causes for the breaker
to trip?
Thanks
