3M Shearbolt Connector QCI Series 2-250, up to 35 kV, 2 AWG

3M Shearbolt Connector QCI Series 2-250, up to 35 kV - Electrical Connectors The 3M Shearbolt Connector QCI Series 2-250 is designed for connecting copper or aluminum conductors ranging from 2 AWG to 250 kcmil. This connector series offers a reliable mechanical connection without the need for crimp tools or dies, making installation efficient and straightforward. It is suitable for use in electrical distribution and wire and cable applications, supporting low and medium voltage systems up to 35 kV. The QCI Series connectors meet or exceed ANSI C119.4 Class 2 mechanical pullout strength requirements, making them a dependable choice for electrical distributors and switchgear suppliers. Specifications Conductor Size: 2 American Wire Gauge (AWG) Voltage Rating: Up to 35 kV Conductor Range Accommodation: 2 AWG to 250 kcmil Material Compatibility: Copper or Aluminum Conductors Connector Outer Diameter: 1.10 inches (27.9 mm) Connector Length with Centering Rings: 4.41 inches (112.0 mm) Connector Inner Diameter: 0.64 inches (16.3 mm) Product Weight: 2.0 lbs Meets ANSI C119.4, Class 2 (40% Mechanical Pullout Strength) Features No dies or specialty tools required for installation; bolts shear below the connector surface to ensure proper torque. Greater contact force compared to standard shearbolt connectors for improved electrical and mechanical performance. Contact disk (friction plate) on bolt end prevents conductor damage, suitable for fine strand conductors. Tapered ends allow smooth splice body transition from connector to cable. Tin plated to resist corrosion. Includes centering rings for smaller conductors to ensure proper alignment. Designed to fit 3M Cold Shrink Splices QS-III and QS4 Integrated Splices. Downloads & Links
