ArTu K

The K range of ArTu cabinets comprises components for making floor-mounted cabinets, in the form of kits.

ArTu K cabinets are available in the following sizes:
- Three useful height sizes: 1600, 1800 and 2000 mm, to which the H=100 mm plinth with removable front/rear flanges must be added
- Four useful working width sizes: 390, 600, 800 and 1000 mm
- Six useful depth sizes: 150 mm (for 630 A fixed Tmax), 225 mm (for 800 A fixed Tmax T6), 300 mm (for 1600 A fixed Tmax T7), 500 mm (for 1600 A fixed Tmax T7), 700 mm (for up to E3 3200 A withdrawable Emax) and 900 mm (for up to E4 4000 A withdrawable Emax). The Tmax XT series can be installed on any of these depths.

Form 2, 3 and 4 segregation compartments can be created inside 500, 700 and 900 mm depth ArTu K cabinets.

The range of ArTu K cabinets meets all the typical installation requirements for primary and secondary distribution switchgear in industrial and service-providing sectors, such as Power Centers, secondary distribution switchgear and substations.
