Thomas & Betts 58168 Copper Compression Lug 1-Hole Barrel

Description:

The Thomas & Betts 58168 One-Hole Standard Barrel Copper Compression Lug is used to terminate 250 kcmil weld cable and flexible copper conductors in power distribution, grounding, and electrical control systems. Commonly installed in switchgear, transformers, substations, motor control centers, utility networks, and industrial electrical equipment, this standard-barrel lug features a peep hole and electro tin-plated high-conductivity copper construction for a reliable, low-resistance electrical connection. Maintenance teams and system integrators use this lug for repair, retrofit, expansion, and replacement of copper conductor terminations.

Applications:

The Thomas & Betts 58168 is designed for terminating 250 kcmil weld cable and flexible copper conductors to busbars, switchgear, transformers, panelboards, grounding systems, and other electrical equipment using a one-hole mounting configuration with a 1/2-inch stud. Its standard-barrel design provides dependable compression performance, while the peep hole allows visual verification of proper conductor insertion before crimping. The lug is suitable for commercial, industrial, utility, renewable energy, and heavy-duty power distribution applications operating on systems rated from 600 V up to 35 kV.
