How does the contactor interlock?
the electrical interlock is deactivated Therefore, it is necessary to use a mechanical interlocking contactor for demanding locations
The normally closed contacts of the KM2 contactor are connected in series to the coil circuit of the KM1 contactor, but if a contactor is welded
Electrical interlocking connection is: KM1 The normally closed contacts of the contactor are connected in series to the coil circuit of the KM2 contactor.
if the two contactor at the same time pull, will occur between the power phase and phase short circuit.
Interlocking is the two contactors can not be connected at the same time, generally used in the motor reversing circuit
