Megabarre Group represents the perfect fusion of a global offer, a highly-qualified service and a great working efficiency.The certificated quality of all its products guarantees the ut-most confidence of the market. Megabarre Group manufacture

busbar system from 25A to 6300A low voltage.Megabarre Group has its manufacturing plants in Brazil, Italy

and Chile and a Branch Office in east Pacific.

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 nom-inal ratings (the L4/L5 circuit with 6 or 6+6 con-ductors rates 25A only). The active conductors are made of electrolytic copper; all along their length they are fully insu-lated by an halogen-free sheet made of self-ex-tinguishing 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 de-mand). The available configurations are 2, 4 and 6 con-ductors 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 avail-able 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 (ex-cept 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 out-lets, or different distances between the outlets are available on demand. The plugs for this version are either phase-se-lecting 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).

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 sin-gle-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-se-lecting 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 “stand-ard plugs” can be installed on this version, too.

The IP55 protection degree is ensured with-out any additional accessory: by a connection joint having a pre-fitted sleeve, at the connec-tion point; by a removable plug-in outlet cover, equipped with a contemporary moulded gasket, at the plug-in outlets position.

Feed units, end covers and mechanical acces-sories designed for suspending the lines and fixing the lamps are also available to complete the system.

The Impact2 busbar trunking system, is de-signed for power transport and distribution and is especially suitable in the electrical switchroom both as a transformer-switchboard or switch-board-switchboard connection and as the mainpower distribution system for industrial, com-mercial and service industry.The Impact2 busbar trunkings system is offered in current ratings from 400A to 5000A with alu-minium conductors and in current ratings from 630A to 6300A with copper conductors (on re-quest are availablehigher current ratings). The current ratings with aluminium conductors are granted with a max-imum ambient temperature of 40°C, while for copper conductors are granted with a maxi-mum 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 perfor-mances (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 (Pe-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+Pe ver-sion with a dedicated earth conductor with a cross-section equal to 50% of the phase cross-section, the 3P+N+Fe+Pe version with a dedicated earth conductor with cross sec-tion equal to 100% of the phase cross-section (isolated) and the 3P+2N+Pe 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 en-tire length. The Impact2 busbar trunkings system is offered in the standard version painted RAL 7035. The Impact2 busbar trunking systems are made with sandwich technology (COMPACT);

the conductor bars are compacted without any space inside the casing and are fully insu-lated using a no hygroscopic halogen free pol-yester 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 out-door 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 avail-able for future maintenances and inspections. A visual signal (red tag) confirms the correct ten-sion on the monoblock. A mechanical interlock device prevents the installer from completing the mechanical connection until the electrical con-nection is correctly completed. The joint mon-oblock doesn’t need any maintenance.
