MOREK MSCL25 Screw Connector for Al/Cu Conductors 6-25mm 12kV with 2 Shear-Off Bolts

The MOREK MSCL25 is a professional-grade screw connector engineered for the reliable joining of aluminum and copper conductors. Designed to accommodate wire cross-sections from 6 to 25mm², this connector is rated for medium voltage applications up to 12kV. It utilizes a robust construction with two integrated shear-off bolts, which are designed to break at a predetermined torque, ensuring consistent and optimal contact pressure for every installation.

Advantages

This connector offers exceptional versatility by allowing the connection of both aluminum and copper conductors, making it a flexible solution for diverse electrical infrastructure projects. The use of shear-off bolt technology eliminates the need for specialized torque tools, as the bolts automatically snap off once the correct pressure is reached. This design feature guarantees a secure, low-resistance electrical connection while significantly reducing the risk of human error during assembly. Its durable build ensures long-term performance in demanding medium voltage environments.

Suitable for

• Joining aluminum and copper conductors in medium voltage networks
• Electrical infrastructure and power distribution projects
• Cable repair and maintenance work
• Installations requiring reliable, high-pressure mechanical connections

When it may not be suitable

This connector is specifically designed for medium voltage applications up to 12kV and is not intended for use in low-voltage residential wiring where smaller, non-shear-off connectors are standard. It is also not suitable for conductors outside the 6-25mm² range.

Key specifications

• Conductor range: 6-25mm²
• Voltage rating: Up to 12kV
• Material compatibility: Aluminum and Copper
• Fastening mechanism: 2 shear-off bolts

How to use

To install the connector, first strip the insulation from the ends of the conductors according to the required length. Insert the conductors into the connector body until they are properly seated. Tighten the two shear-off bolts using a standard wrench or socket. Continue tightening until the bolt heads shear off, which indicates that the optimal contact pressure has been achieved. Ensure the area is clean and free of debris before installation to maintain electrical integrity.

What to consider before purchase

• Verify that the conductor cross-section falls within the 6-25mm² range
• Ensure the application voltage does not exceed 12kV
• Confirm compatibility with your specific cable type

Usage recommendations

Always follow local electrical safety regulations and manufacturer guidelines during installation to ensure the longevity and safety of the electrical connection.
