• MPB3 Feeder Length Aluminium

    Feeder lengths account for the bulk of a busbar run. Distribution lengths are like feeder lengths but with tap off slots.

    Tap off slots allow tap off units to be plugged into the busbar run. The tap off slot outlet and cover are made from a durable, high strength, Class B, 130°C insulation material.

    The tap off slot cover is designed to prevent access to the contacts behind the cover and prevent the entry of dirt, dust or moisture.

    With a standard tap off unit or cover fi tted the Ingress Protection (IP) level is at IP55 but higher levels, up to IP67, can be achieved upon request.

    Straight lengths can be supplied at any length between a minimum of 600mm and a maximum of 3000mm.

    The table below illustrates the diff erent types of build arrangement used depending on the rating of busbar required for the application

  • MPB3 Edgewise Elbow Aluminium

    Edgewise elbows are typically used to make 90° changes in the direction of the busbar system. There are two main kinds, edgewise right and edgewise left. These can be used to turn the busbar route up or down if it is running on its flat, or to turn the busbar left and right if it is running on its edge.

  • MPB3 Flatwise Elbow Aluminium

    Flatwise elbows are typically used to make 90° changes in the direction of the busbar system. There are two main kinds, fl atwise up and fl atwise down. These can be used to turn the busbar route up or down if it is running on its edge, or to turn the busbar left and right if it is running on its fl at.

  • MPB3 Edgewise Offset Aluminium

    An Off set is used to avoid obstacles such as pipes or steel columns and to conform to the structure of the building. It is basically two elbows fabricated into one single piece.

  • MPB3 Flatwise Offset Aluminium

    There are four types of off set section; flatwise off set up and down, and edgewise off set left and right.

  • MPB3-Combination-Elbows---Aluminum-CDL

    Combination elbows are used to conform to the buildings structure and to utilise a small amount of space to change direction by combining both fl atwise and edgewise elbows.

  • MPB3 Panel Flange Aluminium

    Flange connections provide a direct connection to low voltage switchgear, transformer enclosures and other electrical equipment. Cut out details, dimensions and drilling plans are provided with the customer drawings and it is the responsibility of the switchgear manufacturer to provide the opening, drill fixing holes, connecting hardware and busbar risers in their equipment. For proper coordination between the busbar system and the equipment, detailed drawings, including switchgear phase rotation, must accompany the order. Standard fl anges can be off set to the left or right of the section as required.

  • MPB3 Edgewise Flange Aluminium

    A flange combination elbow is a combination of a standard elbow and a standard fl ange. Flange combination elbows are typically used when the minimum leg lengths for either the standard elbow or the standard flange cannot be maintained. A typical example would be when the busbar must lay close to the top of the switchboard, when avoiding other services or when there is reduced head height above the switchgear.

  • MPB3 End Feed Unit Aluminium

    Cable end feed units are used on the ends of busbar risers which are cable fed. They can be on the top of the busbar, feeding down through the building, or they can be located at the bottom of the busbar riser, feeding up through the building.

    The size of the cable end feed unit depends on anumber of factors:

    • rating of busbar
    • size of cable
    • number of cables
    • Is a protective device or an isolator required

  • MPB3 End Caps

    End Caps

    (5)

    End caps are used to safely cap off the end of a busbar run. The end cap units are factory fitted but they can be easily removed on site to allow for the extension of a busbar system. If the busbar run is bottom fed the end cap would be located at the top end of the busbar. If the system is top fed then the end cap would be located at the bottom. In the case of a centre fed system an end cap must be used at both end of the system, one at the top and one at the bottom.
