MOREK MSCL150 Screw Connector for Al/Cu Conductors 25-150mm² 12kV with 2 Shear-Off Bolts

The MOREK MSCL150 is a professional-grade screw connector engineered for the reliable joining of aluminum and copper conductors. Designed to accommodate a wide cross-section range from 25mm² to 150mm², this connector is suitable for medium voltage applications up to 12kV. It utilizes two shear-off bolts that guarantee consistent and optimal contact pressure, ensuring a secure electrical connection without the need for specialized crimping tools.

Advantages

This connector offers significant installation efficiency due to its shear-off bolt technology, which eliminates the risk of under-tightening or over-tightening connections. The robust construction ensures long-term durability and excellent electrical conductivity across various environmental conditions. Its versatility in handling both aluminum and copper cables makes it a highly adaptable solution for diverse electrical infrastructure projects, simplifying inventory management and field assembly.

Suitable for

• Medium voltage cable jointing and termination
• Connecting aluminum and copper conductors in power distribution networks
• Electrical infrastructure projects requiring reliable mechanical and electrical performance
• Installations where specialized hydraulic crimping tools are unavailable or impractical

When it may not be suitable

This connector is not intended for use with conductors outside the specified 25mm² to 150mm² range. It should not be used in applications exceeding the 12kV voltage rating or in environments where the connector material is incompatible with specific chemical exposures.

Key specifications

• Conductor range: 25-150mm²
• Voltage rating: Up to 12kV
• Material compatibility: Aluminum and Copper
• Fastening mechanism: Two shear-off bolts

How to use

To install the connector, first strip the insulation from the cable ends according to the required length. Insert the conductors into the connector body until they are fully seated. Tighten the shear-off bolts using a standard wrench or socket tool. Continue tightening until the bolt heads shear off at the predetermined torque level, which ensures the connection has reached the correct contact pressure. Ensure the area is clean and free of debris before installation to maintain optimal conductivity.

What to consider before purchase

• Verify that the conductor cross-section falls within the 25-150mm² range
• Ensure the voltage rating of the system does not exceed 12kV
• Confirm compatibility with the specific cable type being installed
• Check that the installation space allows for the use of a wrench to tighten the bolts

Usage recommendations

Always follow local electrical safety regulations and manufacturer installation guidelines to ensure a safe and durable connection. Use appropriate cable preparation tools to avoid damaging the conductor strands.
