UniWave Electric
In the evolving landscape of industrial automation, the demand for precision, longevity, and reliability has never been higher. As a premier **China wholesale solid state switch manufacturer**, we recognize that components like Solid State Relays (SSRs) and intelligent circuit breakers are the backbone of smart manufacturing. Unlike mechanical relays, solid-state switches provide high-speed switching without the noise, contact wear, or bounce issues, making them essential for high-frequency applications, temperature control, and sensitive industrial automation equipment.
Located in Liushi, Wenzhou—the "City of Low Voltage Electrical Appliances"—our manufacturing capabilities benefit from a mature industrial ecosystem. We have immediate access to raw material supply chains, advanced R&D talent, and specialized testing facilities that are rarely concentrated in one location elsewhere in the world. This geographical advantage allows for aggressive cost optimization without sacrificing the rigorous quality standards required by global markets.
China-based manufacturers have moved beyond simple assembly. Today, we focus on **Advanced R&D and Precision Engineering**. Our production lines utilize automated winding machines, laser marking, and computerized thermal testing to ensure that every unit meets IEC standards. By sourcing from a specialized Chinese manufacturer, global enterprises benefit from:
Our SSRs are widely used in PID temperature control systems, providing precise switching for heaters and cooling systems, essential for sustainable building energy management.
With high-load current requirements, our vacuum contactors and high-power relays are optimized for safety and durability in electric vehicle charging stations.
Wenzhou UniWave Electric Co., Ltd. is a leading manufacturer specializing in a wide range of electrical products, including Circuit Breakers (RCBO / RCCB / MCB / WiFi Smart MCB / MCCB / ACB), Isolator Switches, Change Over Switches, AC Contactors, Thermal Relays, Magnetic Starters, Solid State Relays, Distribution Boxes, Voltage Stabilizers, and Voltage Protectors. Our company is located in Liushi, Yueqing, Wenzhou, China, famously known as the “City of Low Voltage Electrical Appliances,” offering both a thriving industrial environment and a beautiful natural setting.
With over 25 years of experience in the circuit breaker and AC contactor industry, Wenzhou UniWave Electric has established a strong reputation for quality, reliability, and innovation. Our products strictly comply with IEC standards and have obtained internationally recognized certifications, including SAA, CE, CB (IEC), and ISO9001.
