Wirtschaftlich Fehlerstromschutzschalter

Applicable scope DZ20LE series leakage circuit breakers (hereinafter referred to as the leakage circuit breakers) is a current movement type electronic surplus electricity flow for protection device, mainly is suitable for the ac rated voltage isolator, for 380V and rated current of the distribution network to 630A, as with personal shock protection, also can be used to prevent the equipment, insulation fault current damage caused by fire danger, and can be used to protect circuit and the distribution of energy and power equipment, and can overload and short circuit as less frequent transition. Leakage circuit breakers rated leakage action value according to the actual demands can be clicked adjustment. The product conforms to the standard GB14048.2-2001. Suitable environment Ambient air temperature Around 1 air temperature limit does not exceed + 40 ° c, 2 within 24h around the average air temperature does not exceed + 35 ° c, Air temperature around 3-5 degrees below limits. The location of the altitude 2000m does not exceed altitude. Atmospheric conditions The relative humidity in the atmosphere around 40 ° c + + highest temperature when does not exceed 50%, at lower temperatures, can have high relative humidity, the monthly average wet minimum temperature does not exceed + 25 ° c, the biggest monthly average relative temperature is not more than 90%, and examination to the operation temperature changes in product surface of condensation. Pollution levels: 3 grade. The external magnetic field Leakage circuit breakers installation site near the external magnetic field in any direction should be no more than five times the geomagnetic field. Product model and its meaning Main technical parameters The basic parameters of the leakage circuit breakers (see table 1) Leakage circuit breakers rated limit short-circuit capacity and rated remaining break points on the abilities of the points (see chart 2)
