Our 350A heavy duty substitute Anderson SB plug is a high-power industrial connector developed for heavy-load high-current equipment, fully compatible with the original Anderson SB350 plug in terms of specifications, structure, and performance. Rated for 350A ultra-high continuous current and 600V AC/DC voltage, this heavy-duty plug is designed for large-scale power equipment and high-load energy transmission scenarios, providing a stable and durable substitute solution for genuine Anderson SB350 connectors. It retains the classic hermaphroditic structure and anti-mismatch keying design of SB series plugs, realizing completely interchangeable installation and use.

Adopting heavy-duty reinforced design and industrial-grade raw materials, this substitute plug achieves superior load-bearing and anti-fatigue performance. The ultra-thick high-purity copper conductive terminals greatly improve current carrying capacity and heat dissipation efficiency, ensuring no overheating, no deformation, and stable power transmission under long-term 350A full-load heavy operation. The enhanced engineering plastic housing has super high mechanical strength, strong impact resistance, pressure resistance, and high-temperature resistance, which can withstand harsh working conditions such as heavy mechanical extrusion, high-temperature heat radiation, and severe environmental weathering. The optimized locking structure improves connection firmness, effectively resisting vibration and impact in heavy-duty equipment operation.

This 350A heavy-duty substitute plug is widely used in heavy engineering vehicles, large industrial energy storage systems, container power stations, heavy-duty electric forklifts, and high-power charging equipment. It undergoes strict heavy-load aging testing and mechanical performance testing before leaving the factory, with excellent durability and long service life, fully meeting the long-term stable operation requirements of heavy-duty equipment. As a cost-effective alternative to genuine Anderson SB350 plugs, it solves the problems of high cost and long delivery cycle of imported original parts, providing global industrial customers with high-quality, durable, and economical high-power connector matching solutions.
