Your switchgear needs the same strong support that comes with high-quality materials. We designed our base frame to match the base of our Modular System: with an uncompromised focus on flexibility and strength. Made from 2.5mm galvanized high strength steel, the Logstrup base frame allows for very high weights. Our standard base frame comes with lifting points for a forklift, and the option to add transport wheels or lifting eyes for easy transportation according to your needs.
The framework is the strength of our Modular System. It is based on our original 190mm Modular Framework made from 2mm steel with 5 bends for optimal strength. In combination with our unique corner profile, the Logstrup Modular System allows you to configure almost any solution that matches your project scope. Due to the special surface of the Aluzinc coating, our framework has self-healing ability that makes it very resistant towards rust and corrosion. This makes the Logstrup Modular System suitable for demanding industries.
Cabinet structures (ACA)
Cabinet structures are made of 1.5mm steel coils, which integrate the structures corner profiles with a non-removable side, top, and bottom cover. The cabinet structures may be used in combination with the framework structures, or as smaller stand-alone enclosures. They are available from 1 to 12 modules in width and height, and from 1 to 3 modules in depth. A multiple of threaded and non-threaded holes on the cabinet structures allows for maximum flexibility when it comes to fixing internal parts and configurations.
Logstrup cover panels are manufactured with an automated corner forming technique that eliminates welding. The appearance and quality are superior to any welded option as it is perfectly rounded and less susceptible to rust. Our external cladding is made from 1.5-2mm sheet steel and coated with either Aluzinc or Polyester powder paint. The qualities and self-healing properties of Aluzinc leave the cladding less prone to minor scratches. If your project requires a painted surface, all RAL-colours are available. The powder coating system we use for painted surfaces ensures a consistently high-quality result. Find all available RAL colours here. Doors and cover panels are sealed with a rubber gasket, ensuring ingress up to IP54. The sealing gaskets are tightly and evenly fitted on the entire edge of the cover panel.
Door corners are made with an automated corner forming technique that leaves a perfectly rounded corner without any use of welding. Our doors are superior in quality and appearance to any welded option. The doors are easy to mount due to click mounting. Doors and hinges are designed to open from 90 to 120-degree angles. Extra stabilisers and doorstops are available for larger doors to ensure safe operation. All doors have concealed hinges for a practical and high-quality finish. Doors and cover panels are sealed with a rubber gasket, ensuring ingress up to IP54. The sealing gaskets are tightly and evenly fitted on the entire edge of the cover panel.
Louvres are available on all doors and cover panels and provide natural ventilation within the enclosures. Our Louvres are designed with easy installation and safe operation in mind. The assembly process is simple: An easy two-part click-on system that fits the standard 1.5mm and 2mm enclosures. Louvres can be mounted in the upper and lower section of the enclosure, depending on your needs. Logstrup louvres are available in black or RAL 7035, providing you with an option to customise the design of your project. All Logstrup louvres are available with an extra filter that provides an increased rating of IP54.
Type AGP plates are flat covers intended to be fitted on the top or rear of enclosures. AGP plates are made from mild steel with an Aluzinc coating. The qualities and self-healing properties of Aluzinc prevent the cladding from minor scratches so no paint is necessary. If you do request a painted solution for your project, Logstrup can provide you with flat panels in any RAL-colour. The AGP plates may be fitted with an optional rubber gasket for IP44 protection, and can optionally be delivered with louvres for natural ventilation of the enclosures.
The Logstrup Busbar System consists of modular components, which allow unlimited variations and ratings. Three, four and five-wire systems can be designed with ease. Ratings up to 8500A are standard and tested for both temperature rise and short circuit level. The Busbar System is based on a two-bar-per-phase system, both horizontal and vertical, eliminating time-consuming drilling and bending of copper bars. The busbar joints are attached by bolts and nuts of 8.8 quality in connection with special spring washers, type DIN 6796. This ensures a highly efficient and reliable connection throughout the complete lifetime of the assembly, even during variations in operational and thermal conditions. The connections between the horizontal and vertical bars are made by a special busbar connector system that secures a stable and safe connection. The BXC 11649 spacer has been tested to 2900A. We use special fishplate connections to join two-panel sections. The fishplate connections range from 800A up to 8500A and are easily mounted and ensure a reliable connection. Configuration: Systems up to 8500A can be assembled as standard. A 2 bar, 2x2 bar, or 3x2 bar per phase arrangement is used. This allows connections and extensions to be made without drilling or bending of the copper. The Busbar holder components are manufactured from a high-grade polymer which provides high insulation for the copper bar, good mechanical and thermal strength to meet the stress during a short circuit and ability to withstand variations in temperature during service conditions. The Logstrup Busbar System consists of modular components that allow unlimited variations. 3, 4 & 5 wire systems can be created with ease, while the space between phases can be increased to ease connection to large breakers and facilitate connections of multiple cables. The busbar support insulators are manufactured from a high-grade polymer, which can withstand all the mechanical and thermal stresses involved. All polymers used in the system are CFC and halogen-free. The high short circuit level of the busbar system and the mechanical robustness of the enclosures guarantee a reliable, safe, and long-lasting system suitable for even the most demanding environments.
Fixed Functional Units
Logstrup Modular System allows for panels to be designed with an internal form of separation by steel compartmentation according to IEC 61439-1/2, Form 1-4B, and according to BS 61439-1&2. The Logstrup Fixed units are attached to the switchboard and can therefore not be removed. The fixed units have adjustable depth mounting plates and are nonferrous gland plates.
Our Removable Units (RMU) ensure high protection against contact and can be accessed from the front or rear. The RMU’s are fully re-configurable while live which ensures minimal downtime. It is possible for the RMU unit to be in a tested position if the disconnector has a test position or by an external test function when the disconnector is in off position. The RMU’s have an optional Logstrup coding system that ensures that the units are placed in the right position in the switchboard. For safety measures, our RMU’s have a mechanical interlock on the disconnector shaft. There are two dedicated positions achieved by physical movement of the unit: - Removed position - Connected position Type of electrical connections (acc. To IEC 61439-2) : WF F/D (depending on configuration)
Omega WDU Type A is a withdrawable unit with a position indicator and moving control unit. Our withdrawable units (WDU) have high operational safety and have IP20 Protection in all positions. The units can rate up to 630A, 500kw, 690V, and can hold up to 20 units per section. The WDU’s can be put in a test position and they are fully re-configurable while live which ensures minimal downtime. The outgoing cables are connected to outlets or terminals in the cable section, so the units can be switched out or fixed easily. The auxiliary cables are connected to terminals in the cable section, which can be accessed from the rear or the front. To guarantee the safety of the WDU’s, an optional Logstrup or Harting coding system depending on plug configuration is available, which ensures that the units are placed correctly in the switchboard. The Units have a Mechanical interlock on the disconnector shaft and key. The optional microswitches make it possible to change between isolated, test, and connected position. The units can connect with different communication systems such as DeviceNet and Profibus. 4 dedicated positions achieved by physical movement of the unit: - Removed position - Isolated position (padlocking possible) - Test Position (padlocking possible) - Connected position Sizes: X = 3, 4.

The mini WDU offers high protection for personnel and can be accessed from the rear and the front. The units rate up to 80A, 55kW, and 690V. The unit has an interface box that can be prewired and is removable. To ensure the minimal down-time the Mini WDU is fully re-configurable while live. The mini WDU can have up to 40 units per stack, and the auxiliary controls up to 46 control pins. The mini WDU comes with an optional coding system and can connect with different communications systems such as DeviceNet and Profibus. Sizes: X = 1, 1.5, 2, 3. Y = 1
The modularity of the Logstrup Modular System continues in our cable sections. The cableways can be designed to fit the number of cables and their sizes in the assembled Logstrup switchboard. Standard widths are 450mm, 640mm, and 830mm. A cableway can run horizontally throughout the whole length of the board, at the top and bottom, as well as vertically beside each functional unit section. This provides a complete island around each functional unit section and allows inter-wiring between various units and back to PLC sections with ease.
