2 structure
CLXL type distribution box system enclosed structure, with a thin shell made of steel plate bending. Distribution box in front of the door, the door opened, all electrical equipment Chang Lu power distribution box, in order to facilitate maintenance. Distribution box cover for the lifting rings can be installed with.
CLXL power distribution box of the installed electrical components, with a compact, easy inspection, combined characteristics of a flexible power distribution box installed automatic switches or fuses as short-circuit protection; also equipped with contactors and thermal relays; box can be installed before the meter , voltmeter, and the operation buttons, indicators, switches and so on. When multiple parallel installation, can be attached to the box top closed bus box, height of 300 mm. Before opening the box on the left and right sidewalls, allowing the bus through the.
