4/0 AWG Copper Compression Lug

The 3M MC4/0-38RX is a straight-barrel compression connector built for 4/0 AWG copper conductors. It suits electricians and maintenance crews terminating heavy-gauge cable in panels, switchgear or motor leads. The one-hole ring tongue accepts a 3/8 in stud for secure bolt-down mounting. Each pack supplies 60 pieces for volume jobs.

Purple Die Code 15 Thermal Performance

Copper construction with tin plating provides low-resistance paths that run cool under rated current. The short barrel and purple colour code match die code 15 tooling for consistent crimps that resist heating. No peep hole means a solid barrel wall, reducing hot-spot risk during sustained loads. CSA and UL listings confirm compliance with temperature-rise tests.

Tin-Plated Copper Build and Mounting

The tin-plated copper barrel resists oxidation in damp or industrial environments. A 1.0 in tongue width and 2.35 in overall length fit standard lug pads without crowding adjacent terminals. The 3/8 in stud hole aligns with common bus-bar hardware, so installers can torque directly without adapters. Sixty connectors per pack support repeated service calls or panel build-outs.

Questions about this item

How do I install the 3M MC4/0-38RX lug, and which die code must I use?

Strip the 4/0 AWG cable, insert it fully into the short barrel, and crimp with a die code 15 tool; the purple colour code confirms the correct die.

What maintenance or replacement will the connector need over time?

The tin-plated copper lug is maintenance-free; inspect periodically for corrosion or loose hardware and replace only if the barrel shows damage or overheating signs.

What limit appears first under sustained high-current use?

The 3/8 in stud and 1.0 in width set the mechanical and contact-area limits; sustained loads beyond the lug's rated ampacity will cause heating at the stud interface first.
