Two decades of engineering excellence — from traditional fuse manufacturing to new energy vehicle innovation.
Our Story
Changzhou Terui Electronic Co., Ltd was established in 2004, beginning as a specialized manufacturer of automotive electrical fuses. Over two decades, we've built a reputation for precision manufacturing and uncompromising quality across all provinces in China and more than 30 countries worldwide.
With the global shift toward electric mobility, we established a dedicated New Energy Vehicle Division to design and manufacture high-performance EV high-voltage fuses, photovoltaic (PV) protection fuses, energy storage system (ESS) fuses, and high-performance semiconductor fuse links. Our products comply with IEC 60269, GB/T 13539, ISO 8820, and UL248 international standards.
Backed by German-imported advanced technology, an independent mold R&D center, and a team of expert engineers, we deliver products that meet the highest safety and performance benchmarks — earning IATF 16949, CE, RoHS, and TÜV Rheinland certifications.
