160 percent of loading current or more. Time is from 0 second to hours... You are the one to coordinate it, mate.

Depends on the manufacturer, depends on the model. No way to answer that.

Too late to append:

For example a "Constant Torque" rated drive will typically be 150% for 60 seconds, but a 'Variable Torque" rated drive of the same output power might only be rated for 110% for 30 seconds. Even those values differ from one mfr to another, and some don't use the terms Constant and Variable Torque, choosing instead to say something like Heavy Duty and Light Duty etc. etc.
