UniWave Electric
High-precision low-voltage and medium-voltage electrical components designed in compliance with major global safety standards.
In the modern era of industrial automation, smart infrastructure, and high-voltage grid stability, CE Certified Field Devices act as the indispensable foundation for safety and operation. These field devices—ranging from low-voltage circuit breakers (MCBs, MCCBs, and ACBs) to precision vacuum contactors and electromagnetic protection relays—bridge the gap between physical machinery and automated safety control networks.
As grid complexity increases due to the integration of renewable energy sources, distributed generation, and industrial IoT (IIoT), the market demands highly resilient components. These components must withstand continuous switching operations, transient voltage spikes, and harsh ambient parameters, all while maintaining rigorous compliance with safety standards such as IEC and EN directives.
CE marking stands as a fundamental gateway declaration that the manufactured equipment complies with all relevant European health, safety, and environmental protection legislations. For system integrators, panels builders, and project managers globally, selecting CE certified components ensures seamless regulatory compliance and guarantees high operating reliability under critical faults.
Strategically headquartered in Liushi, Yueqing, Wenzhou, China—world-renowned as the "Capital of Low Voltage Electrical Appliances"—Wenzhou UniWave Electric Co., Ltd. has established itself as an engineering pioneer in manufacturing high-performance power distribution, circuit protection, and automated controls.
Our expansive industrial ecosystem is supported by over 25 years of specialized experience. Over the decades, we have engineered a versatile range of solutions including:
We pride ourselves on strictly adhering to IEC international standards, securing major third-party certifications including SAA, CE, CB, and ISO9001. Our relentless drive toward continuous integration allows us to serve diverse clients across Europe, America, Southeast Asia, the Middle East, and Africa.
How Wenzhou UniWave leverages Liushi's unparalleled low-voltage industrial cluster to deliver efficiency, quality control, and global scale.
The concentration of low-voltage component manufacturers in Liushi, Wenzhou creates a localized supply chain ecosystem. Unlike isolated manufacturing centers, Wenzhou UniWave controls everything from raw material verification to advanced testing processes under one cohesive engineering architecture. This integration ensures rapid response times, optimal production planning, and protection against global supply chain disruptions.
Adapting to the future of smart, digitized, and highly integrated power distribution networks.
We are expanding our smart IoT product lines, such as WiFi-enabled Smart Miniature Circuit Breakers (MCBs). These enable real-time status monitoring, remote power switching, consumption metering, and instantaneous error notifications for predictive maintenance programs in factories and buildings.
By shifting to lead-free contacts, high-performance PA66 fire-retardant thermoplastics, and optimization of electromagnetic coils, UniWave is significantly lowering the carbon footprint and heat dissipation of high-current devices, adhering to global RoHS directives.
For applications where milliseconds mean the difference between operation and massive failure, our solid-state switches and next-gen vacuum contactors are evolving toward faster response arcs, minimizing arc duration and wear on current-carrying copper paths.
Tailored switchgear and protection components serving specific industrial environments across the globe.
Our heavy-duty AC contactors (such as the LC1d40) and dedicated 48V DC drive contactors are specifically optimized for motor control operations in machinery panels, construction machinery (e.g., JLG lifts), and production lines. They guarantee mechanical durability and protect control circuitry from transient surges under severe back-EMF conditions.
In municipal and industrial switchboards, vacuum contactors (such as the Kampa CKJ5) provide reliable switching for capacitor banks. Because capacitor switching creates transient inrush currents, vacuum contactors minimize contacts wear, helping utility operations maintain a stable power factor.
In PV distribution fields, DC/AC isolation switches, high-amperage Air Circuit Breakers (ACBs), and specialized surge protector relays ensure that localized solar installations are isolated during faults. This safety precaution protects costly string inverters from grid-side reverse current faults.
With products like the Zhaoyang ZY Outdoor 12Kv Vacuum Contactor and the ST260E Self-Powered Three Protection Relay, we support regional grid networks. Operating under standard protocols like IEC 61850, these devices prevent phase failures, ground faults, and overcurrent conditions from cascading, which minimizes downtime for localized utilities.
Miniature Circuit Breakers (MCBs) protect final branch distribution circuits in offices and residential buildings. Using standard DIN-Rail mount designs and flame-retardant housings, they protect against overloads and short circuits in high-density panels.
Operating a global distribution network means managing different compliance parameters. Wenzhou UniWave Electric addresses these requirements by building compliance into our design cycle:
Beyond certifications, we provide comprehensive OEM/ODM assistance. Our engineers collaborate directly with project designers to customize trip settings, auxiliary contact arrangements, and terminal connections. This ensures smooth integration with existing switchboards, regardless of the geographic location of the installation.
Technical answers to key inquiries regarding Field Device installation, standards, and production logistics.
A CE certified field device is an electrical component that has been assessed and verified to meet European safety, health, and environmental protection standards. In the context of low-voltage and medium-voltage electrical components, it means the product complies with the EU's Low Voltage Directive (LVD) and Electromagnetic Compatibility (EMC) Directive. This certification ensures safe operation within residential, commercial, or heavy industrial systems without causing electromagnetic interference or hazard.
Unlike standard contactors where contacts open and close in air, vacuum contactors (like the Kampa CKJ5 or ABB ConVac) encase their switching contacts inside a sealed vacuum interrupter. The vacuum extinguishes the arc almost immediately upon contact separation, reducing arc wear, eliminating external sparks, and extending electrical lifecycle. Vacuum contactors are ideal for harsh environments, high switching frequency applications, and high-voltage motor controls, capacitor bank switching, and transformer controls.
Three-phase electrical equipment, particularly induction motors and compressors, is vulnerable to phase failures (loss of a phase) or phase sequence reversals. Phase failure relays (like the CNTD CDV6-416P or FKV-14N) monitor incoming voltages. If a phase fails or the sequence changes, the protector relay trips the control circuit, shutting down the equipment before winding damage or physical damage occurs.
Liushi, Wenzhou is the core hub of China's low-voltage electrical industry. The area offers an efficient ecosystem for component sourcing, manufacturing equipment, raw material supply, and skilled labor. This cluster efficiency allows Wenzhou UniWave to shorten lead times, manage raw material costs, and access the latest testing facilities. This configuration helps us offer competitive pricing and flexible OEM/ODM terms compared to manufacturers located outside of industrial clusters.
Yes, we offer complete OEM (Original Equipment Manufacturer) and ODM (Original Design Manufacturer) services. This includes pad printing custom logos, adapting housing dimensions, adjusting specific current trip settings (Type B, C, or D curves for MCBs), modifying coil operating voltages, and providing tailored packaging options for localized distribution networks.
