Professional fast CJ12-B-150/3 AC contactor

/[Professional Manufacturing] AC Contactor Professional AC Contactor Contactor Supply Scope of Application Series AC contactor is mainly used to make and break circuits in power lines with AC rated operating voltage to (or rated operating current to) and can be used with appropriate thermal Relays or electronic protection devices are combined into electromagnetic starters to protect circuits that may be overloaded. The product complies with other standards.
Product model and meaning
The auxiliary code consists of five parts and is selected in the following order according to needs
br/>The first part uses letters to indicate the general type and does not need to be written to indicate the reversible type
The second part uses digits to indicate the number of poles of the main circuit to represent poles, poles and poles respectively. It does not need to be written out
The third part is used The digit indicates the maximum rated operating voltage and does not need to be written. Table
The fourth part indicates the rated control power supply voltage. The letters are expressed as AC and DC. Write out
Note: This item includes two parts: the number of main contacts and the number of auxiliary contacts. They are represented by numbers as shown in the following diagram
(□□□□) represents the number of main contacts that are normally open and the main contacts that are normally closed. The number of auxiliary contacts is normally open, the number of auxiliary contacts is normally closed
Normal working conditions and installation conditions
The altitude of the installation location does not exceed
The upper limit of the ambient air temperature does not exceed the lower limit and does not fall below< br/>The relative humidity of the air at the installation site does not exceed when the maximum temperature is. Higher relative humidity can be achieved at lower temperatures. The monthly average minimum temperature of the wettest month does not exceed the average maximum relative humidity of the month. Due to the temperature Measures must be taken to change the condensation situation that occurs on the product

Pollution level
In a place without significant shaking, shock and vibration
Main structure
The AC contactor is a formal direct-acting double-breakpoint structure with an iron core located on the lower bridge-shaped double-breakpoint contact. The yoke and static contacts are respectively fixed on the base and body made of insulating materials. on. The armature and the movable contact bridge can move linearly in the body as movable parts. The additional auxiliary contacts are independent components and can be installed on the top or both sides of the contactor. The entire contactor can be quickly installed using standard guide rails or Screws are used for fixed installation.
The AC contactor is an open-type formal installation, a direct-acting double-breakpoint structure, and the auxiliary contacts are installed as independent components on both sides of the main contact and are electrically separated. The iron core is type The structure has a permanent air gap. The base is made of aluminum alloy die-casting (and installed with screws above) and the base is made of unsaturated polyester fiberglass reinforced molding material. The installation method can be screw installation or guide rail installation. The arc extinguishing cover is made of resistant plastic and iron grid. The composition has high breaking capacity and professional AC contactor. Contactor supply/[Professional manufacturing] AC contactor
