Product Description
Ambient temperature
· Short-term maximum temperature +40℃;
· 24-hour maximum average temperature +35℃;
· Minimum temperature -5℃;
· When the equipment is used in temperatures above the above ambient temperatures, it should operate at a reduced capacity;
Environmental conditions
The climate environment during normal operation should comply with the relevant provisions of GB7251.1-2005 and IEC60439-1 standards, with a surrounding relative humidity of 50% at 40℃.
The conditions for the installation site of the switch cabinet indoors should meet the requirements of the corresponding standards. In cases where condensation may occur, ventilation or heating measures will be taken inside the switch cabinet to prevent condensation. If the switch cabinet is installed at an altitude of more than 2000 meters, the equipment should operate at a reduced capacity.
Product features
· The frame uses double-fold edge technology with aluminum-zinc plate;
· The top cover of the horizontal busbar area can be removed;
· It has three functional units: drawer type, movable type, and plug-in type;
· Drawer structure, can accommodate up to 36 circuits;
· Under the condition of not reducing the protection level, three-position conversion of drawer circuits can be achieved;
· Drawer movable component position positioning can match sound, light, and text indicators;
· Complete drawer-type electric operation circuit solution;
