Thomas & Betts 54516 Two-Way Copper Compression Splice Lug

Description:

The Thomas & Betts 54516 Copper Two-Way Compression Splice is used to permanently join two 400 kcmil copper conductors in power distribution and grounding systems. Commonly installed in electrical substations, switchgear, transformers, industrial facilities, utility networks, and commercial power systems, this standard-barrel compression splice is manufactured from high-conductivity wrought copper with an electro tin-plated finish to provide a reliable, low-resistance electrical connection. Maintenance teams and system integrators use this connector for repair, retrofit, expansion, and replacement of high-current copper conductor splice assemblies.

Applications:

The Thomas & Betts 54516 is designed for splicing two 400 kcmil copper conductors in electrical power distribution, grounding, and bonding applications. Its Color-Keyed® compression system ensures the correct die selection for consistent, high-quality crimps, making it ideal for switchgear, panelboards, transformers, substations, utility infrastructure, and industrial electrical installations. The splice is UL listed for 600 V applications and recommended for systems operating up to 35 kV.
