The contactor is a voltage-controlled switching device suitable for systems that frequently turn on and off the AC-DC circuit. It belongs to a kind of control device, and it is one of the most widely used low-voltage electrical appliances in electric drive system, machine tool equipment control circuit and automatic control system.
There are ac contactor, dc contactor and so on.
4. The contactor is a voltage-controlled
switching device suitable for systems that
frequently turn on and off the AC-DC circuit.
It belongs to a kind of control device, and it is
one of the most widely used low-voltage
electrical appliances in electric drive system,
machine tool equipment control circuit and
automatic control system
C According to the types current which run
through the contacts, it can be divided into
AC contactor and DC contactor.

6. The AC contactor is an on-off switch applied in the AC power
environment and is most widely used in various control circuits. It
features low voltage/zero voltage release protection, reliable
operation, stable performance, high operating frequency, and easy
maintenance.
In practical applications, the AC contactor is mainly used as an on-
off switch in the AC power supply line to achieve long-distance
connection and disconnection line functions, such as in frequent
starting and breaking control lines of AC motors, welding machines
and electric heating equipment.

7. From the figure below, it can be seen that the AC contactor is installed in the motor control box and
is mainly used to control the turning on or off of the power supply of the motor so as to control the
start and stop of the three-phase AC motor.

10. The DC contactor is an on-
off switch applied in the
DC power supply
environment, and also has
the characteristics of low
voltage release protection,
reliable operation, and
stable performance.
In practical applications, DC
contactors are used to remotely
switch on and off the DC power
supply or control lines and
common DC motor start-stop
control.
