Scope of Application
CJT1 AC Contactor (Also known as motor contactor), mainly used for the power line of AC 50Hz or 60Hz, rated working voltage to 380V, current to150A, for long-distance making and breaking circuit, and combine with the appropriate thermal relay or electronic protective device into a motor starter to protect circuits that may overload.
CJT1 AC contactors (motor contactor)meet the standards: GB14048.4, IEC60947-4-1 and JB / T8730, is an alternative product of CJ10 AC electrical contactor.
Model and meaning
Some common models:
CJT1-10,CJT1-20,CJT1-40,CJT1-60,CJT1-80,CJT1-100,CJT1-150
Normal operating conditions and installation conditions
Ambient air temperature: -5℃~+40℃, the average does not exceed +35℃ within 24 hours.
Altitude: not more than 2000m.
Atmospheric conditions: the maximum temperature is +40℃, the relative humidity is not more than 50%; at lower temperatures can allow a higher relative humidity, for example, +20℃ up to 90%, special measures should be taken for condensation produced occasionally due to temperature changes.
Pollution level: 3.
Installation category: Ⅲ.
Installation conditions: The inclination of the installation surface and the vertical plane is not more than ±5°.
Shock Vibration: The product should be installed and used in the place without significant shaking, shock and vibration.
Main parameters and technical performance
According to the current level, moto contactor is divided into: 10A, 20A, 40A, 60A, 100A, 150A.
Coil rated control supply voltage Us is: AC (50Hz): 36V, 110V, 127V, 220V, 380V.
Operating conditions: pull-in voltage (85% ~ 110%) Us; release voltage (20% ~ 75%) Us.
The main parameters and technical performance (see table).
Structural features
The motor contactor has the same structure and installation size as CJ10. The arc extinguish chamber is made of arc-resistant plastic arc cover and iron grille, and the base of CJT1-60, 100 and 150 are made of reinforced plastic.
CJT1-10~40A electrical contactor for the double-break direct-acting structure, 60-150A electrical contactor contact system for the double-break direct-acting, electromagnetic system for the lever rotation structure. Contact are using a new copper-based alloy material without silver. With strong resistance to oxidation, contact resistance is small and stable, and have good anti-welding and abrasion resistance, saving precious metals, reduce costs. 20-40A electrical contactor with U-shaped arc extinguishing caps and phenolic plastic arc extinguish chamber, 60-150A electrical contactor use a new staggered arrangement of vertical and transverse grid, DMC arc-resistant plastic arc extinguish chamber, performance of arc extinguishing is good.
