CJX2 Series AC Contactor

CJX2 series AC contactors (hereinafter referred to as contactors) are mainly used in circuits with AC 50Hz or 60Hz, rated insulation voltage of 1000V, and rated current up to 800A at rated working voltage of 380V under AC-3 use category.
The AC contactors can be used to connect and disconnect circuits over long distances and can be combined with suitable thermal overload relays to form electromagnetic starters to protect circuits where operational overloads may occur.

The contactor can be used for frequent starting and control of AC motors.

The contactor is suitable for frequent starting and control of AC motor. The product conforms to GB14048.4 and IEC60947-4-1 standards.

Overview

CJX2 AC Contactor

The Normal Working Conditions And Installation Conditions
  • Ambient air temperature: -5℃ +~40℃ , the average value of which does not exceed +35℃ within 24 hours.
  • Altitude: not more than 2000m.
  • Atmospheric conditions: maximum temperature of +40 ℃ , the relative humidity of the air does not exceed 50%; at lower temperatures can be allowed to have a higher relative humidity, such as +20 ℃ up to 90%, due to temperature changes occasionally produce condensation should take special measures.
  • Pollution level: Class 3
  • Installation category: Class III.
  • Installation conditions: The inclination of the mounting surface to the vertical is not more than ± 5°.
  • Shock and vibration: The product should be installed and used in a place where there is no significant shaking, shock and vibration.
Characteristics of the structure
  • It can be assembled with auxiliary contact set, air delay head, thermal relay and other accessories by block mounting method, and combined into a variety of derived products.
  • AC contactor has the characteristics of small size, light weight, low power consumption, high life, safety and reliability.
  • The contactor body has a pair of normally open or normally closed auxiliary contacts by default for 32A and below, a pair of normally open and normally closed auxiliary contacts for 40A and above, and the product body does not have auxiliary contacts for 115A and above, and F4, F8 auxiliary contacts or air delay head and other accessories can be added.
  • In addition to screw mounting, AC contactors can also be mounted with 35mm [CJX2-09 ~ 95], 75mm [CJX2-40 ~ 95] and 2*35mm [CJX2-115 ~ 170] standard clamp rails
