MSCL95 Al/Cu 25-95mm² 12kV screw connector, 2x aluminum shear head bolt MSCL0952A00

Cable connector for medium voltage installations

The MSCL0952A00 screw connector is an advanced solution for connecting aluminum and copper conductors in applications with voltages up to 12 kV. Equipped with two breakaway aluminum bolts, it ensures fast and secure installation without the need for specialized tools. The product belongs to the MSCL series by Morek, a company specializing in high-quality components for electrical installations.

High-quality construction and materials

The connector body is made of a high-strength aluminum alloy that has undergone a tinning process. The tin-plated finish provides excellent corrosion resistance and compatibility with both aluminum and copper conductors. The two aluminum bolts are coated with a special anti-oxidation grease, which protects against oxidation and guarantees long-term, reliable connection performance.

The design takes into account oil resistance and includes a central barrier, making it resistant to transformer oils and other substances found in transformer stations.

Universal application across a wide range of cross-sections

The connector supports conductors with a nominal cross-section from 25 to 95 mm² for both aluminum (SE, SM, RM) and copper (SM, RM) conductors. For certain copper conductor configurations, the range is narrowed to 25-35 mm² (RE), allowing for precise matching to specific applications.

The product works well with various conductor types: solid, stranded, sector, and round. The compact design requires minimal installation space, which is particularly important for larger conductor cross-sections.

Breakaway bolt mounting system

Breakaway bolt technology eliminates the need for hydraulic tools or specialized torque wrenches. Installation is performed using a standard socket wrench - once the optimal torque is reached, the bolt head automatically shears off.

The bolts are designed so that the breakaway occurs at a precisely defined torque. This guarantees the best possible electrical connection without the risk of under-tightening or mechanical overloading of the conductor.

Safety and reliability in demanding conditions

The MSCL0952A00 cable connector has been tested according to the IEC61238-1 Class A standard - the highest standard for this type of product. Class A signifies full suitability for electrical and industrial installations where high-intensity and long-duration short circuits may occur.

The product is characterized by full water and oil resistance due to the presence of a central barrier. It is suitable for both indoor and outdoor installations, maintaining electrical parameters in harsh environmental conditions.

The IP00 protection rating results from the product's specific nature - as a connecting element mounted inside switchgear or installation boxes, it does not require additional protection against dust or moisture.

International compliance and certification

The product meets the requirements of the EN 61238-1:2003 standard, classifying it as a Class A solution - the highest available category for cable connectors. Certification confirms high manufacturing quality and reliable operation in the demanding operating conditions characteristic of medium voltage distribution networks.

Thanks to its universal Al/Cu design and wide range of supported conductor cross-sections, the connector is suitable for modernizing existing installations as well as new energy infrastructure projects.
