How to implement the start-stop of three-phase ac motor with the contactor?
A master switch, red, green, two button button box, five fuse short circuit protection, 1 overheating protection, ac contactor, thermal relay according to the following diagram together.
The contactor is divided into AC contactor (voltage AC) and DC contactor (DC), which is applied to power, distribution and electricity. A contactor is a term that refers to a magnetic field that is used by an industrial electrical current to generate a magnetic field, which makes the contact close to the control load.
A master switch (knife or circuit breaker), red, green, two button button box, five fuse short circuit protection, a thermal relay, ac contactor, thermal overload protection (rated current is greater than the motor current, coil voltage is consistent with the control circuit voltage), prepare some wires connected line according to the circuit diagram
