AC Contactor Specifications

Note: For electricity-related maintenance and installation, make sure that the operator holds the qualification for electrical work and takes necessary power-off and insulation protection measures.

Features

• 32 pieces of iron core with solid materials, the suction is more smooth and tight.
• Provides silver alloy contacts with strong conductivity and flame retardant housing.
• With copper coils with strong electromagnetic suction when the coil is energized.

Normal Working and Installation Conditions

1. Ambient temperature: -5℃~+40℃, the average value should not exceed +35℃ within 24 hours.

2. Altitude: ＜2000m.

3. Atmospheric conditions: When the temperature reaches 40℃, the relative humidity of atmosphere should be ＜50%. When at relatively low temperatures, it could have higher relative humidity. Monthly maximum relative humidity could be not more than 90%. Special measures should be taken if there is occurrence of dews due to temperature changes.

4. Class of pollution: Class 3

5. Installation category. Ⅲ

6. Installation conditions: The inclination degree between the installation surface and the vertical surface does not exceed ±5°.

7. Impact shock: AC contactors should be installed and used in the place where there are no strong shakes and impacts.

KNOWLEDGE BASE

A contactor is an automated control electrical appliance. The contactor is mainly used to connect or break AC and DC circuits frequently, has a large control capacity and can be operated remotely. Contactor relay can be equipped with the relay to realize timing operation, interlock control, various quantitative control as well as voltage loss and under voltage protection. AC contactor is widely used for the automatic control circuit and to control motor as well as other electrical loads, such as electric heaters, lighting, electric welding machines, etc. Contactors can be classified into AC contactors and DC contactors according to the type of controlled current. Additionally, AC contactors can be classified into AC magnetic contactor and AC vacuum contactor.
