SKU CH-YGX2-6J5NE

Bare copper crimp splice connector for 10 AWG wire, CSA certified and UL listed, rated 600 V and 347 °F, pack of 50

  • TypeElectrical Connectors
  • Handles 10 AWG wires with copper crimp barrel
  • 50 connectors per pack for large wiring jobs
  • Rated to 600 V and 347 °F operating temperature
  • CSA certified and UL listed for code compliance
  • RoHS 2011/65/EU compliant for restricted-substance rules

10 AWG Splice Connector 50 Pack

This pack contains fifty 3M MU10BCX splice connectors rated for 10 AWG conductors. The crimp-style, non-insulated bodies suit electrical and industrial wiring tasks where bare copper contact is required. They are CSA certified, UL listed and compliant with RoHS 2011/65/EU for regulated installations.

Thermals Noise and Power Draw

Maximum operating temperature reaches 347 degrees Fahrenheit while the assembly handles up to 600 volts. Copper contact material provides low resistance under normal load with no active cooling or moving parts to generate noise. The butted seam and 0.135 inch barrel inside diameter maintain consistent conductivity through thermal cycling.

Build Quality and Daily Use

Each connector measures 0.56 inches overall length with a bare metal finish that exposes the copper barrel for direct crimping. Non-insulated design means installers must add separate sleeving or tape where insulation is required by code. The fifty-piece bulk pack supports repeated field terminations without individual packaging waste.

Questions about this item

How do I crimp the 3M MU10BCX splice connector onto a 10 AWG wire, and what step is often missed?

Strip the wire to match the 0.56 in barrel length, insert fully into the 0.135 in inside diameter, and crimp with a die rated for 10 AWG; the step often missed is verifying full insertion before crimping.

What maintenance or replacement will the 3M MU10BCX splice connector need over time?

The bare copper barrel has no insulation to degrade, so inspect periodically for corrosion or loosening at the butted seam; replace any connector showing discoloration or heat damage.

What is the first limit reached on the 3M MU10BCX splice connector under sustained load?

The 347 degrees F maximum operating temperature is the primary thermal limit; sustained current that drives the copper barrel above this temperature risks annealing and connection failure.
