Overview

The ABB 2B350W is a copper two-bolt mechanical connector with an integrated spacer, designed for secure, high-integrity electrical connections in industrial power distribution systems. Part of ABB Installation Products' Type 2BW series, this connector accommodates a main conductor range from 4/0 stranded to 350 kcmil and a tap conductor range from 4 AWG stranded to 350 kcmil, making it suitable for heavy-duty applications where reliable branching or splicing is required. Engineered for copper conductors only, the 2B350W features a single-piece construction spacer that simplifies installation by allowing the connector to swing easily over the conductor. The spacer ensures proper conductor separation and alignment, reducing the risk of short circuits or loose connections. The connector's castings and bolts are manufactured from high-strength copper alloy, while the spacer is made from ductile, high-conductivity copper alloy, ensuring both mechanical durability and optimal electrical performance. The 2B350W utilizes a 3/4" bolt size, providing substantial clamping force to maintain a stable connection under mechanical stress and thermal cycling. Key dimensions include a length (L) of 2.25 inches, height (H) of 2.5 inches, and a bolt head diameter of 0.681 inches. The connector's design supports efficient torque application and long-term reliability in demanding environments, including power distribution panels, motor control centers, and renewable energy systems. This connector is ideal for applications requiring branched conductor connections, such as in industrial machinery, commercial electrical systems, and utility installations. Its compatibility with large conductor sizes makes it particularly useful in high-current circuits where minimal voltage drop and maximum conductivity are critical. The ABB 2B350W is a practical solution for engineers and electricians seeking a durable, high-performance mechanical connector for copper conductors.
