Shearbolt Connector Description
3M Mechanical Shearbolt Connectors, QCI Series are designed to cover a wide range of conductor sizes from 2 AWG to 1250 kcmil. This shearbolt connector design provides excellent performance and features not found in many other shearbolt connectors. No dies are needed for installation: following cable preparation, simply slide the connector over the conductor and tighten the bolts until they shear. The 3M QCI connectors are designed to connect either aluminum and/or copper conductors. The connectors are tin plated to resist corrosion. Individual sizes cover ranges from 2 AWG–250 kcmil, 1/0 AWG– 350 kcmil, 4/0 AWG–600 kcmil, 350–750 kcmil, 500–1000 kcmil and 1000-1250 kcmil.
QCI 500-1000 Kit Contents
Each kit includes the following materials:
• Connector with centering rings, if needed (no centering rings included/required with
1000-1250 kcmil connector)
• Aluminum Foil Tape Pad with Conductive Adhesive
• Instruction sheet
NOTE: A 3M Shearbolt Holding Tool is not included in the 3M Mechanical Shearbolt QCI Series, kits and must be purchased separately. This is highly recommended in order to provide physical support for the Shearbolt Connector during shearing of the bolts during installation on the cable conductor. See Shearbolt Holding Tool Selection Table section for appropriately sized holding tool.
Applications
• To connect aluminum and/or copper conductors from 2 AWG through 1250 kcmil
(MCM)
• For low and medium voltage up to 46 kV (Contact 3M for 69 kV and higher voltage
applications. We offer splice kits that utilize shearbolt connectors specifically designed
for these voltage classes.
