Small distribution board - industrial quality -, 4-row, 56 division units, 150 mm bar spacing, integrated ventilation elements to reduce condensation, screwless PE/N terminal bar with 6 screwable terminal points each, 2.5 - 16 mm², 21 / 2 x 14 screwless terminal points 1,5 mm-4 mm², elastic entries at the top, cover and labeling strips, additional double diaphragm connectors and other accessories, protection class II, rated insulation voltage Ui 1000V AC, rated insulation voltage Ui 1500V DC, halogen-free, VDE tested, impact resistance IK08. The Air® ventilation element prevents condensation while maintaining the high IP65 degree of protection. Any condensation that occurs is transported out of the housing in the shortest possible time by means of air exchange. Due to the constant and high air exchange, the air inside can always mix with the ambient air and transports the moisture to the outside.
