Why Global Electrical Brands Trust D&T Deling Technology for Smart LV Circuit Breaker ODM

As the global transition to smart grids, renewable energy, and digital power distribution accelerates, electrical brands face a dual challenge: delivering intelligent, reliable breaker products while keeping development cycles short and quality consistent. For many industry leaders, the answer lies in partnering with a specialized ODM manufacturer that combines deep technical expertise, large-scale production capacity, and a track record of trusted collaboration.

For nearly 20 years, D&T (Zhejiang Deling Technology Co., Ltd.)has been that partner for top electrical brands across China and beyond. From national grid projects to photovoltaic installations and industrial distribution systems, our smart low-voltage Circuit Breakers sit at the heart of modern power infrastructure.

A Legacy Built on Specialization

Founded in 2007 and headquartered in Yueqing — China’s core electrical manufacturing hub — D&T has grown from an entrepreneurial workshop into a publicly listed NEEQ enterprise (Stock Code: 835881) and a national-level "Little Giant" enterprise specializing in intelligent breakers.

Our core strengths in numbers:

• 37,000 m² modern manufacturing facility with 21 automated production lines
• Daily mccb output exceeding 5,000 units
• 42 in-house R&D engineers across structural, electronic and software disciplines
• 162 authorized patents, including 21 invention patents
• USD 29 million annual revenue with steady year-on-year growth

We hold certifications including National High-Tech Enterprise, Zhejiang Manufacturing Certification, and ISO 9001 / 14001 / 45001 management systems — all reflecting our commitment to excellence in every product we build.

What Makes D&T a Preferred ODM Partner

1. End-to-End Mechatronics-Software R&D

Unlike many manufacturers that only assemble hardware, D&T controls the full R&D chain — from mechanical structure design and electronic module development to embedded software and cloud platform integration.

This integrated approach enables true primary-secondary integration design, simplified wiring, optimized performance, and faster custom development. We operate our own state-of-the-art SMT workshop and in-house laboratory for environmental testing, EMC verification, and temperature-rise testing, ensuring every innovation is validated before mass production.

2. Flexible Customization, Fast Time-to-Market

With 60% of our revenue from ODM projects, we have refined a customer-centric collaborative development model. Our engineering team works directly with clients to tailor products for specific standards, functions and scenarios — whether it is PV-specific islanding protection, Type B DC leakage for EV chargers, or prepaid cost-control logic for metering applications.

We maintain dedicated inventory reserves for key partners and have a proven track record of turning custom requirements into mass-produced products on tight timelines.

3. Quality Built Into Every Production Step

Quality is not an afterthought at D&T — it is embedded in our manufacturing process. Every smart breaker goes through a rigorous 5-step workflow:

1. Precision assembly with QR-code traceability for key components
2. Initial calibration of metering and protection parameters
3. Extended aging test with real-time data monitoring
4. Post-aging re-calibration for long-term accuracy
5. Final full-function testing before packaging

This systematic approach ensures consistent reliability, even in harsh operating environments.

A Complete Product Portfolio for Modern Power Systems

D&T’s product lineup covers the full spectrum of low-voltage distribution needs:

• CBRM5E Series Smart MCCB — Flagship all-in-one model with metering, remote control and auto-reclosing
• CBRM3EL/5EL Series — Smart MCCB with residual current protection for PV and metering scenarios
• CBRB7BL Smart MCB — IoT miniature breaker with Type B DC-tolerant leakage protection for EV charging
• CBRW3 Series ACB — Intelligent air circuit breakers up to 4000A for heavy industry and power generation
• CBRM5Kd Series — Compact high-breaking MCCB with DEKRA certification, ideal for export markets

Our solutions are deployed across smart grids, photovoltaic grid-connection, industrial & commercial distribution, data centers, metro systems, and rural grid modernization projects.

Trusted by Industry Leaders

D&T is a long-term ODM supplier to many of the most respected names in the electrical industry, including CHINT, DELIXI, BULL, People Electric, Schneider Electric, NARI, XJ Group and Pinggao Group.

Selected landmark deployments:

• Xiong’an Intelligent Transformer Station Project — 30,000 units
• Shandong PV Grid-Connection Upgrade Project — 65,000 units
• Xi’an Metro Project — 20,000 units
• National Type B EV Charging Pile RCD Project — 100,000 units

These projects are a testament to both our product reliability and our ability to deliver at scale.

Innovating for the Decarbonization Future

As the world accelerates toward carbon neutrality, D&T continues to invest heavily in R&D for new energy distribution, digital grid intelligence and energy efficiency management. Our vision is clear: to become the No.1 ODM brand for circuit breakers and a leading expert in intelligent power distribution technology.

For our partners, this means access to forward-thinking products that are ready for the next generation of power systems.
