Overview

ABB BA 400-332 is a CSA-listed tin-plated aluminum mechanical splice designed for copper and aluminum conductors rated up to 75°C. This dual-rated connector accommodates #4 AWG to 400 kcmil conductors, making it ideal for heavy-duty industrial, commercial, and utility applications where reliable splicing is critical. The connector measures 1-1/8 inches in length and width, with a depth of 1-1/4 inches, including a .093-inch anti-rotation bar to prevent conductor slippage during installation or operation. The set screw is 11/16-16 UNS-2B with a 3/8-inch hex socket head and measures .937 inches in length, ensuring secure torque retention. The tin plating provides corrosion resistance in harsh environments, while the aluminum construction offers lightweight durability. This splice is CSA certified for use in wet or dry locations, meeting NEC and CEC standards. Common applications include power distribution panels, motor control centers, and renewable energy systems where copper-to-aluminum transitions are required. The break-thru tap feature allows for easy installation without pre-drilling, reducing labor time. Order SKU BA 400-332 for a reliable, code-compliant splicing solution.
