MISTRAL 25-40 A LIGHTING AND SMALL POWER DISTRIBUTION The MISTRAL bus-bar trunking system, used to distribute lighting and low power, is mainly installed in industrial, commercial and service buildings. The MISTRAL range rates 25A and 40A of nominal ratings (the L4/L5 circuit with 6 or 6+6 conductors rates 25A only). The active conductors are made of electrolytic copper; all along their length they are fully insulated by an halogen-free sheet made of self-extinguishing thermoplastic material. The casing (used as PE conductor as well) is available either made of hot galvanized steel or hot galvanized and plasticized steel (white colour, RAL 9016), being the latter particularly suitable where resistance to chemical agents is required (different colours are available on demand). The available configurations are 2, 4 and 6 conductors within a single casing, and 2+2, 4+2, 4+4 and 6+6 conductors within a double casing, mechanically separating the two circuits along the whole length. The MISTRAL bus-bar trunking system is available in two versions: - with standard plug-in outlets ; - with inter-locked plug-in outlets. The version with standard plug-in outlets is equipped with orange colour plug-in outlets (except for the 4+2 conductors one), pre-installed along the unit length in the number of 2, 3 or 6 on a single side for the single-casing element, and 2+2, 3+3, 6+6 on both sides for the double casing element. Different number of plug-in outlets, or different distances between the outlets are available on demand. The plugs for this version are either phase-selecting plugs (with or without fuse) or pre-wired plugs (with cable, without fuse). The plugs have different colours to identify the pre-wired circuit. The plugs do not have any mechanical device to restrain their insertion into the bus-bar element, except for the 4+2 conductors configuration, where it s possible to create an inter-lock on the two conductors side, by using the LOCK/A plugs (to be used, for instance, as emergency circuit). sides for the double casing element. Different number of plug-in outlets, or different distances between the outlets are available on demand. The plugs for this version are either phase-selecting plugs (with or without fuse) or pre-wired plugs (with cable, without fuse). The plugs have different colours to identify the pre-wired circuit. The plugs have a mechanical device restraining the insertion into the bus-bar element: the red colour plugs (LCK/A) can be inserted into the red colour plug-in outlets only, while the white colour plugs (LCK/B) can be inserted into the white colour plug-in outlets only. All the standard plugs can be installed on this version, too. The version with inter-locked plug-in outlets is supplied with white and /or red colour plug-in outlets, pre-installed along the unit length in the number of 2, 3 or 6 on a single side for the single-casing element, and 2+2, 3+3, 6+6 on both Feed units, end covers and mechanical accessories designed for suspending the lines and fixing the lamps are also available to complete the system. The IP55 protection degree is ensured without any additional accessory: by a connection joint having a pre-fitted sleeve, at the connection point; by a removable plug-in outlet cover, equipped with a contemporary moulded gasket, at the plug-in outlets position.
MISTRAL LIGHTING AND SMALL POWER DISTRIBUTION 25-40 A IP55 Without adding accessories Used to distribute electric power with nominal ratings of 25A and 40A (the L4/L5 circuit of the elements with 6 or 6+6 conductors, from 40A, rates 25A only), the straight element is ensuring the IP55 protection degree in its standard version already (without any additional accessory). The casing (used as conductor as well) is made of hot galvanized steel sheet or plasticized steel.

Patented! IMPACT 2 400-6300A HIGH POWER TRANSPORT AND DISTRIBUTION The Impact 2 busbar trunking system, is designed for power transport and distribution and is especially suitable in the electrical switchroom both as a transformer-switchboard or switchboard-switchboard connection and as the main power distribution system for industrial, commercial and service industry. The Impact 2 busbar trunkings system is offered in current ratings from 400A to 5000A with aluminium conductors and in current ratings from 630A to 6300A with copper conductors (on request are available higher current ratings). The current ratings with aluminium conductors are granted with a maximum ambient temperature of 40 C, while for copper conductors are granted with a maximum ambient temperature of 50 C. On request are available configuration, for higher ambient temperature. Thanks to a casing made with an aluminium alloy extruded profile which gives to the product great mechanical rigidity and resistance performances (with a very light weight), the product can be used in its standard configuration also in boundary ambient conditions. The standard product is offered in the 3P+N+PE with the neutral and the phase being of the same cross-sectional area and the earth (-casing) cross-section more than 100% of the phase cross section. Phase and neutral conductors are made by one, two or three bars depending on the rated current; in the two and three bars version, the bars are opportunely connected at each junction. Available are also the 3P+N+Fe/2+ version with a dedicated earth conductor with a cross-section equal to 50% of the phase cross-section, the 3P+N+Fe+ version with a dedicated earth conductor with cross section equal to 100% of the phase cross-section (isolated) and the 3P+2N+ version with the neutral with cross section equal to 200% of the phase cross-section. Aluminium conductors are galvanically tinplated along their entire length while on request, the copper conductors can be galvanically tin- or silver-plated along their entire length. The Impact 2 busbar trunkings system is offered in the standard version painted RAL 7035. The Impact 2 busbar trunking systems are made with sandwich technology (COMPACT); the conductor bars are compacted without any space inside the casing and are fully insulated using a no hygroscopic halogen free polyester sheath (thermal class 150 C or 155 C). This technology guarantees the products high performance in relation to voltage drop values even in high current and long runs. The standard protection degree is IP55 (on request IP66 only for transport lines without tap-off units). For outdoor installations an extra protection (canopy) is used. The electrical connection is achieved by a monoblock system with one or more bolts with an anti- screwing spring which guarantees the electrical continuity between the units of the run. The self-breakable bolt is double headed; the first head is used for the installation (breaking at 85 Nm torque moment) carried out without any special tool, while the second head will be available for future maintenances and inspections. A visual signal (red tag) confirms the correct tension on the monoblock. A mechanical interlock device prevents the installer from completing the mechanical connection until the electrical connection is correctly completed. The joint monoblock doesn t need any maintenance.
