Download informationW1 series intelligent universal circuit breakers (hereinafter referred to as circuit breakers) are used in distribution networks with AC 50Hz, rated voltage up to 660V (690V) and below, rated current 200A-6300A, to distribute power and protect lines and power supply equipment from overload, undervoltage, short circuit, single-phase grounding and other faults. The circuit breaker has intelligent protection function and precise selective protection, which can improve the reliability of power supply and avoid unnecessary power outage. At the same time, it has open communication interface and can carry out "four remote" to meet the requirements of control center and automation system.
Ⅰ、The upper limit of the surrounding air temperature should not exceed +40℃, the lower limit should not be lower than -5℃, and the average value of 24h should not exceed +35℃.
Ⅱ、Installation site at an altitude of not more than 2000m above sea level.
Ⅲ、Atmospheric relative humidity does not exceed 50% when the ambient air temperature is +40°C; higher relative humidity is possible at lower temperatures; the monthly average maximum relative humidity for the wettest month is 90%, while the monthly average minimum temperature for that month is +25°C and takes into account the frosting that occurs on the product surface due to temperature changes.
Ⅳ、Pollution level: Class 3
Ⅴ、Installation conditions: can be installed vertically or horizontally
Ⅵ、Installation category: The main circuit of the circuit breaker and the undervoltage permeable air is in love with the primary coil of the power transformer and the installation category of the rest of the auxiliary circuit and the control circuit is category III.
