L have a 7.7kw motor wired in delta in terminal box, l have fitted a direct on line contactor fitted with 16 amp overload and 32amp circuit breaker.each time l switch on the circuit breaker trips out,thought it was overload single phasing,so remove overload from circuit and wired motor direct to contactor,but still tripping out at breaker at switch on. what l,m doing wrong.
Check & confirm the following
1. delta connection of the motor is done properly, with the combination of different windings.
2. check the quality of the 3 pole mcb or check with other one.
