Detailed Description

1.XRM exchange low-voltage distribution lighting control cabinet XRM exchange low-voltage distribution lighting cabinet apply to high-rise buildings, hotel and residential buildings. realizing lighting distribution circuit switching, leakage, overload, short circuit protection in low-voltage distribution systems which is Ac 50hz, under rated voltage 380v. 2.Use environment (1) the ambient air temperature no higher than + 40 degrees Celsius, no less than -5 degrees Celsius, and average temperature is no higher than + 35 degrees Celsius within 24 hours. (2) clean air, relative humidity does not exceed 50% while in + 40 degrees centigrade, allow higher relative humidity when temperature is lower, for example: relative humidity is 90% in + 20 Celsius. (3)sea level elevation no higher than 2000m. (4) Installation position should be placed vertically, gradient no more than 5 degrees. (5) Installation location with no violent vibration and impact, and insufficient to corrosion electrical components. (6) products with leakage protection devices,external magnetic field intensity of installation location not more than five times the geomagnetic field in any direction. 3. main technical data (1) this product mainly divided into 6, 9 and 12, 15, 18, 24, 30, 36 units for customers to choose. (2) maximum total input current is 20, 25, 32, 40, 50, 63, 100a. (3) biggest shunts output current is 6, 10, 16, 20, 25a. (4) rated insulation voltage 500v . (5) rated short-time tolerance current 3ka . (6) rated leakage current,main inlet line no more than 100ma. single output circuit no more than 50ma. (7) rated leakage no operate current is 50% of leakage operating current . (8) rated leakage time less than 0.1 seconds.
