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:
It can be installed with auxiliary contacts block, time relay and current-limited contacts block, and thermal relay, then to be other derivative products;
This series contactor has small volume, light weight, less power loss, long life and safe and reliability etc;
The contactor can be equipped with 1NO auxiliary contact or 1NC auxiliary contact(less than 32A), and 1NO auxiliary contact+1NC auxiliary contact(more than 40A). In addition, it can be equipped with F4 auxiliary contactor block (2blocks or 4blocks);
In addition to use screw to install, contactor can be tightened with the standard installing rail of 35mm (sc09~95) and the standard installing rail of 75mm(SC40~95)
