Rated working voltage: 380/660V

Maximum working current of main bus: 5000A

Rated withstand current of main bus: 100KA/1s

Rated withstand current of main bus (peak): 220KA/1s

Applied standard: DIN40050, GB7251.1, JB/T9961, IEC529, IEC439-1

Ingress protection ratings: IP30, IP40, IP54

Application Environment

Ambient temperature: -5℃~+40℃, the average value of 24h does not exceed +35℃

Altitude: ≤2000m

Relative humidity: monthly average ≤90% (the average temperature of the month is +25℃); relative humidity ≤50% (when the ambient temperature is +40℃). The relative humidity is related to the ambient temperature. The lower the ambient temperature, the higher the allowable relative humidity. For condensation caused by temperature changes, take appropriate protective measures (such as adding drainage holes).

Transportation temperature: -25℃~+55℃, the average value of 24h does not exceed +70℃

Installation site: no severe impact, no serious pollution and chemical corrosion, no conductive dust or explosion hazard. Should prevent rain and moisture.

When this device is used in offshore oil drilling platforms and nuclear power plants, a separate technical agreement should be signed.
