In the rapidly evolving landscape of global power distribution and HVAC/R (Heating, Ventilation, Air Conditioning, and Refrigeration) industries, the Over Current Relay (OCR) stands as the first line of defense against catastrophic system failures. As a leading China-based supplier and manufacturer, Ningbo Taojun Refrigeration Equipment Co., Ltd. has observed a significant shift towards intelligent, sensitive, and high-reliability relay systems. These components are no longer mere switches; they are critical sensory organs of the electrical system that ensure motor longevity, prevent thermal runaway, and optimize energy consumption.
Our 38-year legacy, beginning in 1988 as the Xiangshan Refrigeration Accessories Factory of Zhejiang University, provides us with a unique vantage point. By combining theoretical academic rigor with four decades of manufacturing data, we deliver "Information Gain" to our clients—providing not just a product, but a deep understanding of how circuit protection interacts with refrigeration cycles and industrial automation.
Ningbo Taojun Refrigeration Equipment Co., Ltd. is located in Xiangshan, Ningbo, a strategic coastal hub for international trade. Founded in 1988, our company's leading products include filter driers, check valves, air conditioning valves, condensers, and advanced relay components. In 2021, we were recognized as a National High-Tech Enterprise, a testament to our commitment to innovation and process optimization.
Our partnership with domestic giants like Haier, Midea, and Gree, alongside global leaders such as Whirlpool and Electrolux, has forced us to maintain a 0.05% defect rate through our proprietary 5D quality system. With core equipment imported from Germany and R&D talent from the University of Science and Technology of China, we bridge the gap between "Made in China" and "Engineered in China."
The transition from mechanical bimetallic strips to microprocessor-based relays allows for real-time data logging and predictive maintenance, reducing downtime by up to 40%.
As industrial panels become more compact, the demand for high-capacity relays in smaller footprints has surged. Taojun’s design team focuses on heat dissipation in tight spaces.
Global regulations like RoHS, REACH, and WEEE are now mandatory. Our products use 100% recyclable packaging and lead-free soldering processes.
Our products, particularly the TAOJUN Copper Filter Driers and relay housings, are engineered for extreme environments.
Global procurement teams today face three major challenges: Supply Chain Volatility, Compliance Fragmentation, and Technical Obsolescence. Ningbo Taojun addresses these through a holistic "Partner-Centric" model:
We provide full documentation for ISO 9001:2015, UL (USA), and CE (Europe). Our team handles the complexities of international standards so your engineers don't have to. With a 24-hour complaint resolution window, we act as a local partner regardless of your time zone.
We are currently integrating AI-driven diagnosis into our AC control systems. Future over-current relays will not just "trip"; they will communicate the reason for the trip to the cloud, allowing for remote fleet management of industrial refrigeration units.
A: Unlike generic factories, we are a "Zhejiang University" spin-off with a 38-year focus on refrigeration-specific electronics. Our R&D team consists of professors and PhDs who specialize in thermodynamic and electrical synergy.
A: Yes. We offer fully customizable sizes, shapes, and trip curves. We accept MOQs as low as 500 units for specialized industrial applications.
A: We use high-purity copper and specialized protective coatings that pass a 500-hour damp heat test, making them ideal for marine or tropical refrigeration applications.
A: We offer a 72-hour global delivery for stock items and a robust MES-managed production cycle for bulk orders to ensure on-time delivery.
Innovation is the essence of our group culture. From the early days in 1988 to our current status as a global leader in refrigeration parts, we have adhered to four core values: Honesty, Innovation, Responsibility, and Cooperation. We strive to build a win-win situation with every client, integrating resources and allowing professional people to give full play to their specialty. Whether you are seeking a reliable over current relay supplier or a comprehensive OEM partner for HVAC/R components, Ningbo Taojun is your trusted ISO 9001-certified partner.
