CFB2s-63 Small circuit breakers

Scope of application
The CFB2 - 63s miniature circuit breaker is suitable for the overload and short - circuit protection of lighting distribution systems or squirrel - cage motor distribution system lines with an alternating current of 50Hz, a rated voltage of 400V and below, and a rated current of up to 63A. It can also be used for the infrequent operation and switching of lines under normal conditions. This circuit breaker is applicable to industrial, commercial, high - rise and civil residential buildings and other places.
Product compliance standards: IEC60898 - 1, GB10963.1.
Working conditions
● Ambient air temperature: - 20°C to + 60°C, and the average within 24 hours shall not exceed 35°C. The normal operating temperature range is - 5°C to + 40°C. When used in an environment with a temperature ranging from - 40°C to - 5°C, it is necessary to inform our factory when placing an order. When the ambient temperature is higher than + 40°C, it is necessary to use it according to the derating coefficient table.
● The altitude of the installation location shall not exceed 2000m. When it is higher than 2000m, derating is required for use.
● The relative humidity of the atmosphere shall not exceed 50% at the maximum ambient temperature of + 40°C. At lower temperatures, a higher relative humidity is allowed. For example, the relative humidity is 90% at + 20°C, and the condensation on the product surface due to temperature changes should be considered.
● Pollution degree: Class 2.
● Protection level: IP20.
● Installation category: Class II, Class III.
● It is installed using the TH35 - 7.5 type installation rail.
● The inclination of the installation surface from the vertical plane shall not exceed 5°.
