This is a grounded delta system, one leg of the transformer is 190v to
ground(commonly called high or wild leg), the other legs are 120v to
ground. Center tap of one transformer is grounded and can be used as
neutral conductor. You can feed single phase 230v loads using any two
phase conductors,120v loads as long as you do not use high leg. 3 phase
supply is fine as you get 230 volts between any phase.
To answer the original question NO, 11 amps exceeds 6 amps get a proper
motor starter and overloads as required by the NEC, it will probably
keep you from smoking the motor one day.
