Product Description

Product Description

LV terminals are LV electrical connection components that comply with American electrical standards (such as IEEE). The conductors are made of tin plated copper material, and the insulation parts are made of epoxy resin. They are designed for safe and efficient wire connections and are widely used in distribution cabinets, industrial equipment, and building electrical systems. Its core features are modular structure, high current carrying capacity, and environmental adaptability.

LV terminals are modular electrical connectors designed for low-voltage systems (≤1,000V AC/1,500V DC). They ensure secure wiring in industrial, commercial, and residential applications while complying with:

Region	Key Standards	Focus Area
North America	UL 1059, IEEE 488, NEC Article 408	Safety, current ratings
Europe	IEC 60947-7-1, EN 60998	Mechanical/electrical performance
Asia-Pacific	GB/T 14048 (China), JIS C2810 (Japan)	Material & environmental tests
