In the modern era of electrification, the Dual Interlock CB Level Transfer Switch stands as a pinnacle of safety and reliability. As a leading ODM supplier and factory, we recognize that power distribution is not just about moving energy; it's about ensuring absolute continuity for hospitals, data centers, and advanced manufacturing lines. Our Dual Interlock technology provides both mechanical and electrical interlocking, preventing the simultaneous closure of two power sources—a critical fail-safe that protects millions of dollars in downstream equipment.
This whitepaper explores the technical nuances of CB-level (Circuit Breaker level) automatic transfer switches (ATS), the integration of Industry 4.0 in our Chinese manufacturing hubs, and the future roadmap of intelligent power management. By focusing on Information Gain, we provide stakeholders with the data needed to make informed procurement decisions that align with global safety standards like IEC 60947-6-1 and UL 1008.
We are transitioning from traditional switching to "Smart Switching." Future CB-level switches will utilize Digital Twin technology to simulate wear and tear, allowing operators to predict maintenance needs before a failure occurs.
Our R&D is focused on reducing the transfer gap. By utilizing advanced electromagnetic actuators, we aim to achieve transition times that exceed current CB-level benchmarks, ensuring zero-latency for sensitive electronics.
Aligned with the EU RoHS directive, our future product lines will phase out all heavy metal components, replacing them with high-conductivity composite alloys that are 100% recyclable.
Located in the Economic Development Zone of Yueqing City, Zhejiang Province, our facility sits at the heart of China’s electrical industrial cluster. We have been committed to the research, development, and production of high-end low-voltage electrical appliances, with products widely utilized in electric power, infrastructure, energy, and electronics.
Our standard workshop spans over 12,000 square meters, housing 212 employees, including 20 professional technical personnel. With 180 units of production and testing equipment, we ensure every Dual Interlock CB Level Transfer Switch meets the highest global standards.
We use Statistical Process Control (SPC) tools to improve the quality of process control, ensuring zero-defect manufacturing for our Dual Interlock systems.
From raw materials and accessories to production dates and key electrical parameters, every unit is logged in our traceability system.
Leveraging the Yueqing industrial cluster, we maintain a 98% on-time delivery rate even during global logistics fluctuations.
Dual power supply promptly switches to backup, ensuring continuous operation of pump units.
High reliability for harsh environments, providing safety in volatile industrial zones.
EU ROHS compliant switches ensuring guest safety and environmental protection.
Supporting China's rapid PV expansion with high-voltage molded case switches.
For global enterprises, procurement of a Dual Interlock CB Level Transfer Switch involves more than just price. It requires a partner who understands local electrical codes and international compliance. We provide:
PC-level switches are designed to carry and withstand short-circuit currents but do not have an integrated overcurrent protection. CB-level switches, like our Dual Interlock series, utilize circuit breakers as the switching mechanism, providing integrated short-circuit and overcurrent protection within the unit itself.
The Dual Interlock system uses a physical mechanical link and an electrical logic circuit to ensure that the secondary power source cannot be engaged until the primary source is fully disconnected. This prevents hazardous "back-feeding" or phase-to-phase short circuits.
Yes. As an ODM specialist, we can customize the electrical parameters, including rated current (up to 1600A and beyond) and voltage levels, to suit specific regional grid requirements or industrial applications.
We adhere to strict quality inspections according to incoming goods, process, and finished product standards. We use SPC tools and have established a full-process traceability system for every switch produced.
