It sounds like the wires came in contact with each other probably the wire insulation wore off with vibration. the wires are forming an arc similar to welding until the arc is terminated by the circuit breaker when it trips. wires need to be replaced make sure all connections starting from the circuit breaker all the way to the compressor are tight you don,t want wires melting and causing a fire it can damage your equipment, your property to say the least.. Best of luck.
