Operating conditions Altitude ≤2000m. Ambient temperature Range: -5℃ ~ +40℃, with daily average ≤ +35℃. Atmospheric condition: when the highest temperature is +40℃, the relative humidity of air shall be no more than 50%, higher relative humidity shall be allowable at lower temperature, for instance air humidity may reach 90% at +20 ℃. As for dews, which contigently appear due to change of temperature, special steps should be taken. Pollution Level: Level 3. Inclination between installation p...

Product Features 1. Miniaturization design Product volume miniaturization can meet the customer’s personality needs of the product installation size. 2. Size uniform The same shell level, different breaking capacity (S, M), different functions (air, leakage) product installation size is completely consistent. 3. The function of the reasonable parameter setting Circuit breaker can realize long-time delay overload inverse time, short circuit instantaneous action protection functions such ...
