Motor circuit breaker acts on the electric motor to adjust the protection of the electric motor in the event of an overload
The motor circuit breaker acts on the electric motor to adjust the protection of the electric motor in the event of an overload. The advantage of the motor circuit breaker in the electric motor has a current adjustment, where the rated current of the electric motor can be configured. So if the motor circuit breaker has an adjustment scale that starts with six amps at the end 10 amps this means that you need to turn on the electric motor with rated 6 to 10 amperes.
The protection device against lack of phase in the network is fundamental to avoid that the electric motor burns. If there is an accident with the electric conductors or with the electric power supply, it may cause a break in one of the phases that feed the electric motor. Of course, if the electric motor does not have this protection device, the electric motor could burn in a short time and this will cause enormous damage. If there is a phase failure, the electric motor may have its coil burned out quickly because it has no protection. https://www.mrosupply.com/hydraulics-and-pneumatics/hose-reels/2517108_ez-shw-175_coxreels/
