20 Years of Expertise: Why D&T Deling Technology Is Your Go-To Smart LV Circuit Breaker ODM Partner
For nearly two decades, the global electrical industry has undergone a profound shift — from passive, hardware-focused power distribution to intelligent, connected grid systems. As smart grids, distributed photovoltaics (PV), energy storage, and EV charging infrastructure expand at an unprecedented pace, demand for customized, reliable smart low-voltage (LV) Circuit Breakers has surged. For brands, system integrators, and switchgear manufacturers worldwide, partnering with an experienced ODM provider that combines technical depth, scalable production, and strict quality control is no longer an option — it is a competitive necessity.
At D&T (Zhejiang Deling Technology Co., Ltd.), we have spent 20 years refining our craft in LV circuit breaker design and manufacturing. Today, as a national-level "Little Giant" specialized enterprise and a trusted ODM partner for top electrical brands globally, we deliver intelligent breaker solutions that power the worldwide smart energy transition.
Beyond White-Label: The New Standard for Smart Breaker ODM
Gone are the days when ODM meant simply rebranding standard hardware. Modern smart breakers integrate precision metering, IoT connectivity, remote control, auto-reclosing, and scenario-specific protection logic — all of which require expertise in mechanical design, electronic engineering, and embedded software development.
Brands today need more than a factory; they need a technical collaborator that can translate application requirements into fully optimized, compliant, and cost-effective products. This is exactly the gap D&T has been filling for years: full-stack ODM support from initial concept to mass production.
What Sets D&T Apart as Your ODM Partner
1. Two Decades of Proven Industry Legacy
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 recognized leader in intelligent LV circuit breakers.
Our operational 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 authoritative credentials including National High-Tech Enterprise certification, Zhejiang Manufacturing Certification, and ISO 9001 / 14001 / 45001 management system certifications — all reflecting our unwavering commitment to excellence.
2. Full-Stack Mechatronics R&D Capability
What truly differentiates D&T from conventional manufacturers is our end-to-end in-house R&D system. Unlike assembly-focused factories that source third-party electronic modules, we design and develop every critical layer ourselves:
- Mechanical structure and arc-extinguishing systems
- Electronic measurement and protection modules
- Embedded firmware and communication protocols
- Cloud platform compatibility and OTA upgrade functions
This integrated approach enables true primary-secondary integration design, reduces wiring complexity, improves product reliability, and allows us to respond rapidly to custom requirements. We also operate a state-of-the-art SMT workshop and a fully equipped in-house laboratory for environmental testing, EMC verification, and temperature-rise testing, ensuring every innovation is rigorously validated before mass production.
3. Quality Built Into Every Production Step
Quality is not an afterthought at D&T — it is embedded in every stage of manufacturing. Every smart breaker goes through a rigorous 5-step workflow to ensure long-term reliability:
- Precision assembly with QR-code traceability for all key components
- Initial calibration of metering and protection parameters
- Extended aging test with real-time data monitoring
- Post-aging re-calibration to guarantee long-term accuracy
- Full-function final inspection before packaging
Our products comply with IEC 60947-2 standards and carry DEKRA certification, making them suitable for global markets and high-demand industrial scenarios.
4. Comprehensive Product Portfolio for Every Application
D&T’s full product lineup covers nearly all low-voltage distribution scenarios, giving ODM clients a one-stop solution:
- CBRM5E Series Smart MCCB: Flagship all-in-one model with primary-secondary integration, Class 0.5S metering, four-remote control and fast auto-reclosing
- CBRM3EL/5EL Series: Smart MCCB with residual current protection, designed for PV grid-connection and metering box applications
- CBRB7BL Smart MCB: IoT miniature breaker with Type B DC-tolerant leakage protection, ideal for EV charging piles and DC-rich environments
- CBRW3 Series ACB: Intelligent air circuit breakers up to 4000A for heavy industry, power generation and large infrastructure
From smart grid distribution automation to rural grid renovation, from solar PV systems to data centers, our products are engineered to perform reliably in real-world conditions.
5. Trusted by Industry Leaders Worldwide
D&T is a long-term strategic 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.
Our track record of landmark deployments speaks for itself:
- 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 validate both our product reliability and our ability to deliver high-volume orders on schedule.
Our Commitment to the Future of Smart Power
As the world accelerates toward carbon neutrality and grid digitalization, D&T continues to invest heavily in next-generation smart distribution technology. Our vision is clear: to become the No.1 ODM brand for circuit breakers and a globally recognized expert in intelligent power distribution.
