The switchgear is completed with: - blind IP65 and ventilated IP41 type side panels; - blind and transparent doors, fitted with safety glass which can be mounted on all sides IP The mounting positions are established previously so as to guarantee the insulation distances and perfect alignment of the apparatus on the front panel. Furthermore, the kit plates are of the self-centring type and are fitted with threaded bushings to provide easy assembly of the apparatus from the front.
The aluminium DIN rail has three established mounting positions, corresponding respectively to the depths of the System Pro M, Tmax and Isomax circuit-breakers. It is fitted with double DIN 35 section front and rear , and the rear part can be used to support the duct, up to 60x80mm; - kit for air circuit-breakers consisting of sturdy supporting crosspieces and of the front panel; - universal kits, consisting of back plates and blind front panels, which allow assembly of generic apparatus.
The panels have vertical mm modularity and are fitted with an invisible hinge on the outside, which can be mounted either on the right or on the left, and which guarantees panel earthing, making the equipotential connection superfluous. In the case of modular and moulded-case circuit-breakers placed side by side in the same row, the special section must be used which allows the assembly position of the circuit-breakers to be adapted correctly so that the same modular panel can be used.
When the circuit-breakers do not take up the whole window of the panel, the spaces can be closed using the hole covers. Within the K series of ArTu switchgear with , and mm depths, segregation compartments of Form 2, 3 and 4 can be made in conformity with the IEC Standard, for the whole range of moulded-case circuit-breakers with rear terminals, simply by using the closed functional frame, the installation kits in the segregated version and the special segregations.
The distribution systems, which can be used inside the ArTu switchgear, consist of: - shaped section busbars up to A; - flat busbars up to A; - flexible busbars; - Unifix cabling system, structured up to A; - dividers up to A. The extremely compact dimensions of the system allow the busbars to be mounted directly inside the switchgear, positioning them horizontally or vertically, on the back or on the side of the structure, keeping front access, also thanks to the practicality of the scaled type busbar holder.
These same installation possibilities are offered inside the cable container and the structures with reduced depth. Available in xx and xx H x W x D with optional cable container with transparent or plain door.
