Stall current for a 775PRO from Vex is 134 Amps (according to Vex)
Trip time for a 40 amp snap action breaker @ 3x load is 0.5 to 1.1 seconds. (according to AndyMark)
Whether you stall the 775PRO or not depends on your gear ratio, not the motor itself. Stalling a 775PRO is very bad for the motor as it has an integrated cooling fan on the shaft so as you stall the motor (highest heat output) you also stop the cooling fan. This will eventually let out the magic smoke.
