3M™ Mechanical Shearbolt Connectors QCI Series offer easy installation without crimp tools or dies. This connector covers a large range of sizes, from 2 AWG to 250 kcmil. It can be used with copper or aluminum conductors. Centering rings are provided for smaller conductors. 3M™ Shearbolt Connectors are designed to shear off just below the outer surface of the connector body to eliminate the need to file. These connectors can be used for applications up to 46 kV and can be packed in a kit with 3M™ Splices QS-III or purchased separately.
The 3M™ Mechanical Shearbolt Connector is a mechanical screw connector with stepless shear bolts. The stepless shear bolt shears at the same location regardless of AWG or metric conductor and comes with a centering ring for smaller conductors. In addition to the stepless shear, the bolt employs a contact disk end which avoids damage to the conductor strands while providing increased contact force. The connector is compatible for use with 3M™ Cold Shrink QSIII and QS4 Medium Voltage Splices. Its built-in centre stop allows for correct positioning. The connector meets the requirements of ANSI 199.4, class 2 pull out and RoHS 2011/65/EU Compliant.
