External dimensions	Width [mm]	Height [mm]	Depth [mm]	Weight [kg]	Width [mm]	Height [mm]	Depth [mm]	Weight [kg]
ZK-1a, ZK-1b	400	660	250	11,0	400	860	250	14,5
ZK-2a ZK-2b, ZK-2c, ZK-2d	600	660	250	22,5 20,0	600	860	250	29,0 26,5
ZK-3a ZK-3b, ZK-3e ZK-3c ZK-3d	850	660	250	25,0 25,5 23,5 25,0	850	860	250	31,5 32,5 30,5 32,0
Maximum cross-sections of connection cables	120 mm²				240 mm²

connection boxes may be made in three versions: free-standing, wall-mounted and recess-mounted,
in case of a recess-mounted connection box, the dimension of the recess should be increased by 10 mm compared to the connection box dimensions (as in the drawing of the ZK-1 connection box),
it is possible to manufacture connection boxes with different dimensions, adapted to the needs at the location.

Foundation

Free-standing connection boxes are installed on prefabricated concrete foundations. These foundations enable feeding in of cables from four directions. The view, dimensions and example foundations of cable connection boxes was presented on figures below.
