HSW1-6300A HSW1-6300A phone 13356158515 landline: Lingwu 7761716961 QQ: 1293219973 The circuit breaker appearance art , high breaking, zero arcing, with a variety of intelligent protection function, can selectively protect precise action to avoid unnecessary power outages and improve reliability of power supply. The circuit breaker can be widely used in power plants, factories, mines, and modern high-rise buildings, especially intelligent building distribution systems, wind power, solar power and other green projects are also widely used. Product lines or can progress under the line; drawer-type circuit breaker with isolation feature. Standard: GB 14048.2, IEC 60947-2; has obtained "CCC" certification. Normal working conditions and installation conditions ① the ambient air temperature limit of not more than + 40 ℃, lower limit of not less than -5 ℃, 24h average does not exceed + 35 ℃; Note: The lower limit of -10 ℃ or -25 ℃ working conditions, users should declare the factory; upper limit of more than + 40 ℃ or below the lower limit -10 ℃ or -25 ℃ working conditions, users should consult with the factory. ② installation site altitude does not exceed 2000m. ③ atmospheric conditions atmospheric relative humidity in the ambient air temperature does not exceed + 50% 40 ℃ when, at lower temperatures can have a higher relative humidity, the wettest month of the monthly mean maximum relative humidity of 90%, while the month The average minimum temperature of + 25 ℃, due to temperature changes on the surface of condensation in the case must be taken. Exceeds the user should consult with the factory. ④ Protection class: IP30; Pollution Level: 3 ⑤ use category: Class B or Class A ⑥ Installation category rated working voltage of 660V (690V) and below the circuit breaker and undervoltage release, power transformer primary coil for installation category Ⅳ ; auxiliary circuit and control circuit installation category Ⅲ. ⑦ installation conditions require the installation of circuit breakers shall present specification, the vertical inclination of the circuit breaker does not exceed 5 degrees (mine circuit breaker does not tilt more than 15 degrees).
