A wide selection of cable lugs and cable connectors ERKO is a guarantee of a reliable connection. In addition to tubular connectors Cu, Al and Al-Cu we also have shear off screw connectors and medium voltage connectors. Learn about their features.
Shear off screw connectors are an alternative for traditional crimping .Properly selected shear off screw connectors provide versatility and speed of connection. Shear off screw connectors from ERKO can be used on wires with different structure and for a wide range of cross-sections.
An example of the SZS shear off screw connector is the connector , that is used with the voltage between 1-36 kV. SZN shear off screw connector is also made of aluminum . The standard version of this connector is tinned, but the non-tinned version is available on request
