Working and Installation Condition:

♦ Ambient air temperature: -5℃--+40℃ and average not more than +35℃ within 24 hours;

♦ Altitude: ≤ 2000m;

♦ Air condition: when the highest temperature is +40℃, the air relative humidity is not up to 50%, but the higher humidity is allowed at lower temperature. Like, 90% humidity at 20℃. The condensate dew should be considered when at lower temperature;

♦ Pollution degree: Class 3

♦ Installation category:III

♦ Protection degree: IP20

♦ Installation condition: the gradient angle between installation side and vertical side should not be more than ±5℃

♦ Impact and vibrattion: the contactor must be installed and operate under the circumstances of no obvious shaking, impact and vibration.

 

Structure characteristic:

♦ Safety design against electric shock, more safe and reliable

♦ The feature of small volume, light weight, arcing chamber is enclosed, small electric arcing distance

♦ The arc-extinguishing construction is novel, abrasion of the contacts is small, with a long electric life

♦ The operation of the magnet that many advantages such as good reliability, resistant impact, tiredness and so on significant advantages
