Product Description
The Square D DCC C-419 is an industrial-grade, heavy-duty mechanical terminal lug engineered for reliable power distribution. Precision-machined from high-strength 6061-T6 extruded aluminum alloy, this lug is designed for use in Square D panelboards, switchgear, and neutral assemblies. It features a robust single-barrel design capable of terminating large-diameter main feeders up to 600 kcmil (MCM) or dual parallel conductors in specific configurations.
Every DCC C-419 is finished with premium electro-tin plating to ensure exceptionally low contact resistance and to provide a permanent barrier against oxidation and galvanic corrosion. As a dual-rated (AL9CU) connector, it is certified for the safe termination of both copper and aluminum conductors.

Key Features & Benefits
-
OEM Specification: Designed to meet the exact tolerances of Square D / Schneider Electric electrical equipment for seamless fit and code compliance.
-
Large Stud Capacity: The 5/8-inch mounting hole allows for much higher mechanical torque and structural security than standard 1/2-inch lugs.
-
Mechanical Efficiency: Features a rugged internal hex set-screw that provides high-pressure termination—eliminating the need for expensive hydraulic crimping tools or specialized dies.
-
Bimetallic Protection: The tin-plating allows for safe copper-to-aluminum transitions, preventing the thermal expansion failures common in untreated terminals.
-
Industrial Durability: Extruded aluminum construction offers superior structural integrity under thermal cycling compared to cast alternatives.
