CKJ5 permanent magnet type low voltage 1.14kv vacuum contactor
  Detailed introduction

1.Product Introduction

This series of vacuum contactors main used for AC 50-60hz,main circuit rated voltage 1.14kv below the rated current from 80A-630A power network systems for remote making and breaking and frequent starting and control of AC motors,transformers and capacitor banks and other occasions.

This series of vacuum contactor conform to the GB14048.4 standard,to current international advanced level.

The contactor with vacuum switch tube for arcing element,have no arcing, long life,without noise,small volume,safety,reliability, etc.

2.The use of the environment conditions

2.1.Ambient temperature -30 ℃ ~ +40 ℃.

2.2.Installation site altitude does not exceed 2000m.

2.3.The air relative humidity at the highest temperature of 40 + not more than 50%.Low temperature allows a higher relative humidity.

3.Action performance

When the ambient air temperature in -30 ℃ ~ +40 ℃,contactor in the control power supply voltage for rating (US) the 85% to 110% range are should be able to reliable suction close,used in mine contactor,in control of the power supply voltage for rating (US) the 75% to 110% range are should be able to reliable suction together.Release the voltage should be not higher than the rated control power supply voltage (US) of 75%,in the ac rated frequency under the release voltage or should not be less than 20% of the US,the dc is not less than 10% of the US.
