  • 3/case
  • Meets ANSI C119.4, class 2 and RoHS 2011/65/EU Compliant
  • Withstands a maximum temperature of 221 degrees F (105 degrees C)
  • Accommodates wire size of 2 AWG to 250 kcmil (stranded)
  • Stepless shearbolt barrel and contact pad ensures optimun contract pressure for reliable performance and mechanical pull-out strength
  • Rated for 35 kV voltage applications
  • Made of aluminum for good conductivity and has corrosion-resistant tin plating
  • Size 4.41-in x 1.1-in O.D.
  • Ideal for connecting copper, aluminum or transition from copper to aluminum conductors
  • Built-in center stop enables correct positioning
  • 3M™ QCI Shearbolt Splice Connector is ideal for connecting aluminum, copper and aluminum to copper conductors. Its aluminum construction offers high conductivity and an electro-tin-plated finish resists corrosion. Tapered ends enable smooth splice body transition from the connector to the cable. For applications up to 69 kV and withstands temperatures of 221 degrees F (105 degrees C).
  • 3M™ QCI Shearbolt Splice 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 compatable for use with 3M Cold Shrink QSIII and QS4 Medium Voltate Splices. Its built-in center stop allows for correct positioning. The connector meets the requirements of ANSI 199.4, class 2 pull-out and RoHS 2011/65/EU Compliant.
