Circuit Breaker Or Overload For Single Phase Motor

Recommended Posts

Dear Friends;


We have 220V, 1HP, 8A, 1430rpm motors for blowers. To protect the motors against overloading, we want to add safety. As normal circuit breaker do have thermal characteristics, so can we use 9/10A circuit breaker instead of overload type circuit breaker 6.5A-9.5A which usually available in 3poles? If a normal circuit breaker costs $3 then a 3pole overload type circuit breaker costs $30. So kindly guide me if we can use the circuit breaker or not if not than what is the reason.
