thermal protection for motor (49)
thermal protection for motor (49)
(OP)
for motor protection circuit, we have two scheme. Scheme A is fuse/CB + contactor + thermal over load, Scheme B is fuse/CB + contactor + relay. I find Scheme B is popular right now ( I am not sure I am right). Please give me your suggestions based on your experience.
thanks
thanks

For larger motors powered from load centers we use a metal frame breaker and a relay... no contactor.
