Question:

The difference between the contactor and the relay, the symbols in the circuit

The difference between the contactor and the relay, the symbols in the circuit

Answer:

His common points are small signal control large signal, symbols are K and KM Different points of the relay for low-power signal control and signal isolation, such as solenoid valves and so on Contactor for high power and high load signal control of three - phase motor

Contactor is the master, the equivalent of the switch, in the circuit connected or cut off the main circuit, the symbol is generally: C Relay is the auxiliary control, for the control circuit, it has a lot of types, the common symbol: J, subdivided down, there are intermediate relay: ZJ Time relay: SJ, thermal relay: RJ, and so on.
