ECO-NHZ1-63A IEC60269-2 33kA DC1000V gG 63A DC pv solar power fuse with base NHZ1B

ECO-NHZ1-63A IEC60269-2 33kA DC1000V gG 63A DC pv solar power fuse with base NHZ1B

Solar dc fuses is primarily used to protect the system wiring from getting too hot and catching fire. Secondly, it’s also used to protect devices from catching fire or from becoming more seriously damaged if there is a short circuit.

3.1 Ambient temperature: no more than 40 ℃, the average value measured in 24h does not exceed 35 ℃, and the average value measured within one year is lower than this value. Ambient air The minimum temperature is -5 ° C.

3.2 Altitude: not exceeding 2000m

3.3 Atmospheric conditions: The air is clean and its relative humidity does not exceed 50% at a maximum of 40 ° C; it can have a higher relative humidity at lower temperatures Degrees, for example, at 20 ° C, the relative humidity can reach 90%, under these conditions, due to temperature changes, moderate condensation may occur by accident.

3.4 Pollution Degree: Grade 3

3.5 Installation Category: Class III

NHZ series DC knife contact fuse has the characteristics of small size, light weight, low power and high breaking capacity. Power distribution devices with a rated voltage of DC 1000V and rated current of 800A are used for overload and short circuit protection.
