AC/DC contactor has four main components:
( 1) the electromagnetic system, including the attraction coil, a movable iron core and the static iron core;
( 2) the contact system, comprising three main contacts and a two normally open, two auxiliary normally closed contact, it and the movable iron core is connected together are linked with each other;
( 3) arc extinguishing device of large capacity, general AC contactor with arc extinguishing device, in order to quickly cut off the arc, from burning the main contact;
( 4) insulation casing and accessories, all kinds of spring, a transmission mechanism, a short circuit ring, wiring column.
IEC utilization categories
The current rating of the AC/DC contactor depends on utilization category. Example IEC categories in standard 60947 are described as:
AC-1 - Non-inductive or slightly inductive loads, resistance furnaces
AC-2 - Starting of slip-ring motors: starting, switching-off
AC-3 - Starting of squirrel-cage motors and switching-off only after the motor is up to speed. (Make Locked Rotor Amps (LRA), Break Full Load Amps (FLA))
AC-4 - Starting of squirrel-cage motors with inching and plugging duty. Rapid Start/Stop. (Make and Break LRA)
Normal working conditions and installation conditions
1. Surrounding air environment is from -5 to +50 degrees Celsius.
2. Altitude does not exceed 2000m.
3. The tilt with the vertical is not more than 5 degrees.
4. The pollution degree of installation sites is level 3.
5. Installation category is class II.
6. No space of significant shake and shock and vibration.
