The lugs are compatible with standard crimping and compression tools, allowing quick, safe field installation. They connect seamlessly with NIU Electric accessories such as distribution blocks, clamps, and connectors, forming a unified system. Suitable for power cabinets, switchgear, control panels, and outdoor feeders, the LC2-3 Solderless Terminal Lugs deliver durable performance, low maintenance needs, and long service life in modern electrical systems.
These solderless terminal lugs simplify installation while maintaining mechanical strength and electrical stability. The compression structure eliminates soldering errors and withstands vibration, thermal expansion, and heavy load cycles. The LC2-3 Solderless Terminal Lugs minimize contact resistance, enhance current flow, and prevent loosening over time—offering consistent performance in field or factory conditions.
Each LC2-3 Solderless Terminal Lug is made from high-conductivity tinned copper or aluminium alloy for excellent electrical contact and corrosion protection. The precision-formed barrel and compression body guarantee consistent pressure and firm conductor grip, reducing the risk of hot spots or current loss. The smooth surface finish improves oxidation resistance, ensuring long-term reliability in harsh or humid environments.
The NIU Electric LC2-3 Solderless Terminal Lugs are high-quality electrical connectors designed to provide secure, low-resistance terminations without the need for soldering. They ensure dependable performance for both aluminium and copper conductors in industrial, commercial, and power-distribution applications.
