MOREK MSCL50 Screw Connector for Al/Cu Conductors 10-50mm² 12kV with 2 Shear-Off Bolts

The MOREK MSCL50 is a professional-grade screw connector engineered for the secure and reliable termination of aluminum and copper conductors. Designed for medium voltage applications up to 12kV, this connector accommodates a conductor cross-section range of 10 to 50mm². It utilizes two shear-off bolts that are specifically calibrated to provide the precise contact pressure required for optimal electrical conductivity and long-term mechanical stability in demanding infrastructure environments.

Advantages

The primary advantage of the MOREK MSCL50 lies in its specialized shear-off bolt technology, which eliminates the need for torque wrenches by ensuring the bolt head breaks off only when the correct tightening torque is reached. This feature guarantees consistent installation quality and prevents damage to the conductor or the connector body. The connector is constructed from high-conductivity materials compatible with both aluminum and copper, minimizing the risk of galvanic corrosion and ensuring a durable, low-resistance connection suitable for medium voltage systems.

Suitable for

• Medium voltage electrical distribution networks
• Connecting aluminum and copper power cables
• Infrastructure projects requiring reliable cable terminations
• Industrial electrical installations

When it may not be suitable

This connector is not intended for use with conductors outside the specified 10-50mm² range, as improper sizing can lead to poor electrical contact or mechanical failure. It is also not suitable for low-voltage applications where a simpler, non-shear-off connector would be more cost-effective.

Key specifications

• Conductor range: 10-50mm²
• Material compatibility: Aluminum and Copper
• Voltage rating: Up to 12kV
• Fastening mechanism: 2 shear-off bolts

How to use

To install the MOREK MSCL50, first prepare the conductor by stripping the insulation to the required length. Insert the conductor fully into the connector bore. Tighten the two shear-off bolts sequentially using a standard wrench or socket. Continue tightening until the bolt heads shear off at the predetermined torque level, which indicates that the optimal contact pressure has been achieved. Ensure the installation area is clean and free of debris before proceeding.

What to consider before purchase

• Verify that the conductor cross-section falls within the 10-50mm² range
• Confirm the compatibility of the connector with your specific cable type
• Ensure the 12kV voltage rating meets the requirements of your electrical system

Usage recommendations: Always follow local electrical safety regulations and manufacturer guidelines during installation. Ensure that the connector is properly insulated according to the specific medium voltage cable system requirements after the mechanical connection is completed.
