Overview

The ABB UB4K Insulated Connector Kit is a 4-terminal set screw type connector designed for high-current applications up to 750 amperes at 600 volts. This kit includes one UB4 connector rated for conductor sizes from #2 AWG to 350 kcmil, along with four WB20P insulating sleeves pre-installed for immediate use. The set screw design ensures a secure, vibration-resistant connection while the insulated sleeves provide dielectric protection and simplify installation in confined spaces. Typical applications include motor control centers, panelboards, switchgear, and industrial distribution systems where reliable, high-current terminations are required. The UB4 connector body is constructed from durable copper alloy, offering excellent conductivity and corrosion resistance. The WB20P sleeves are color-coded for easy identification of conductor sizes and meet UL 486A-B standards for insulation integrity. This kit is ideal for new installations or maintenance upgrades where code compliance and long-term reliability are priorities. The wide conductor range eliminates the need for multiple connector sizes, reducing inventory requirements and simplifying procurement. Installation requires only standard tools—no special crimping equipment is needed—accelerating deployment in time-sensitive projects.
