MSCM150 Al/Cu screw connector 50-150mm² 36kV, 2x breakaway aluminum bolt MSCM1502A00

Shear bolt technology for high-voltage applications

The MSCM150 screw connector is a professional solution for connecting aluminum and copper conductors in high-voltage installations up to 36 kV. It utilizes innovative shear bolt technology, which enables the installation of terminations using a standard socket wrench - without the need for specialized crimping tools or other complex devices.

This advanced technology allows for precise control of the tightening torque. Aluminum bolts are designed to shear off at an exactly specified moment, guaranteeing an optimal electrical and mechanical connection. As a result, the installer achieves a repeatable installation result without the risk of over-tightening or under-tightening the connection.

Material and structural versatility

The connector body is made of a high-strength aluminum alloy, which has subsequently undergone a tinning process. This material combination ensures compatibility with both aluminum and copper conductors, eliminating galvanic issues resulting from direct contact between different metals.

The design supports conductors with cross-sections of 50-150 mm² for aluminum and 50-120 mm² for copper, covering RE (solid round), RM (stranded round), and SM (sector) types. This cross-section range allows for flexible solution selection within a single installation project.

Protection against oxidation and operating conditions

A key protective element is the bolts coated with a special anti-oxidant grease. This protective layer eliminates all types of oxidation at the electrical contact points.

The connector features a waterproof design, making it suitable for both indoor and outdoor installation.

Compactness and system compatibility

The compact design requires significantly less space during installation, especially with larger conductor sizes and in applications where mounting space is limited.

The product is compatible with most termination kits offered by various manufacturers.

Certification and quality standards

The connector has undergone rigorous quality testing in accordance with the IEC61238-1 class A standard. This certification includes both thermal cycle tests and short-circuit tests - meaning the product is suitable for use in distribution and industrial networks, where it may be exposed to short circuits of relatively high intensity and duration.

Class A according to the EN 61238-1:2003 standard ensures resistance to dynamic loads occurring during power grid operation.
